Welcome to Fox Pest Control’s ultimate guide on cockroaches! Whether you’re facing a cockroach problem or just want to learn more about these creepy crawlers, we’ve got you covered. This guide dives into everything from fascinating facts and species types to their behaviors and how to get rid of cockroaches. Let’s dive in!
What Do Cockroaches Look Like?
How Many Cockroaches are There in the World?
It is estimated that there are trillions of cockroaches all over the world—yep, trillions! But that’s just an estimate – we really don’t know how many cockroaches are on earth. With over 4,500 species out there, they can be found pretty much everywhere except Antarctica. Even though most of them don’t like to hang out near humans, they’re still one of the most common bugs on the planet.
Cockroaches love warm, humid places, so tropical and subtropical regions are their favorite hangouts. Countries in South America, Africa, and Southeast Asia are crawling with them because the weather is just right. Because cockroaches hate the cold, you won’t find many of them in super chilly places. Antarctica is completely cockroach-free because it’s way too cold and there’s nothing to eat. Even in freezing spots like parts of Canada, Scandinavia, or Siberia, cockroaches are pretty rare—though they can still survive indoors where it’s warm and cozy.
Cities are like cockroach heaven—they’ve got everything roaches need: food, water, and tons of places to hide. You won’t find them as much in rural areas, unless there’s a lot of human activity or waste for them to feed on.
Cockroaches Have Been Around for a Really, Really Long Time…
Like since dinosaurs were stomping around! Scientists agree that cockroaches have been scuttling across the Earth for a very long time, but there’s some debate about exactly how long. Estimates range between 300 million and 125 million years. Either way, one thing’s clear—cockroaches have been here long enough to witness some serious history, from the age of dinosaurs to today! That makes them one of the oldest creatures still hanging out with us today. They’ve seen ice ages, survived mass extinctions, and adapted to pretty much everything the world has thrown at them. Honestly, it’s like they’ve got a VIP survival pass.
How have they lasted so long, when so many other species have gone extinct? Cockroaches would totally win any Survivor competition they entered – they’ve got mad survival skills! They can live without food for a month, survive on just a drop of water a day, and even hold their breath for 40 minutes. Plus, they’re super sneaky and fast, so catching one feels like a victory in itself. These little critters might be ancient, but they’re definitely built for modern-day life too!
We said above that there are over 4,500 different species of cockroaches around the world, but only about 30 live where people are. The rest are doing their own thing in forests, deserts, and other natural habitats. So, which ones are the cockroach MVPs in our homes? The American, Australian, brown-banded, German, and Oriental cockroaches. These miscreants are the ones that give the whole roach family its bad reputation!
If cockroaches have taken up residence in your home, don’t worry—we’ve got you covered. With a little help from the Fox Pest Control pros, we can stop them from living rent-free in your space. After all, just because they’ve been around forever doesn’t mean you have to share your home with them! We’ve got some great tips to make your home less inviting to these insects, so stay with us!
Do Cockroaches Bite, Sting, Damage Property, or Spread Disease?
When it comes to cockroaches, people have a lot of questions—and for good reason! These little critters may not look all that intimidating, but they can cause plenty of headaches. So, let’s break it down and answer your most burning questions.
Are Cockroaches Harmful to Humans?
When it comes to cockroaches, people often wonder just how dangerous they really are. The truth? While they don’t sting and rarely bite, cockroaches are far from harmless. These pests are known to spread bacteria, trigger allergies, and contaminate surfaces they crawl across. In other words, even though they aren’t aggressive, cockroaches are still a health hazard you don’t want in your home.
First off, cockroaches can bite, but it’s pretty rare. They’re not aggressive like some pests, and they’d much rather scurry away than confront you. If they do bite, it’s usually because they’re desperate for food, which doesn’t happen often in homes where they have access to crumbs, garbage, or other snacks. Their bites might cause minor irritation, but nothing serious.
Stinging? Nope, not a thing. Cockroaches don’t have stingers, so you don’t have to worry about them delivering a painful jab like a bee or wasp. However, don’t breathe a sigh of relief just yet, because cockroaches can still cause trouble in other ways.
When it comes to property damage, cockroaches are sneaky culprits. They love munching on things like paper, glue, and even fabric. That means they can ruin your books, wallpaper, clothing, or even cardboard boxes if they’re left unchecked. They also leave droppings and stains behind, which can be tough to clean up.
Here’s a fun fact for you – cockroaches can bite with a force 50 times greater than their body weight! About ten years ago, scientists from the UK and Germany wanted to know how insect jaws work. They started with ten American cockroaches and put them something that looked like a medieval torture device to measure their bite force. What they found was that, if comparing bite force to body weight, a cockroach bite packs about five times more force than a human bite. Crazy, right? It’s a good thing they don’t have a taste for people!
Can Cockroaches Make You Sick?
Absolutely. Cockroaches spend their time in some of the filthiest places—garbage, drains, and even sewage systems—picking up bacteria and pathogens as they go. When they invade your home, they track these germs across your floors, counters, and food prep areas. This can lead to food poisoning, stomach issues, and other infections. So if you’ve been wondering, “Can cockroaches make you sick?” the answer is yes.
What Diseases Do Cockroaches Carry?
These pests aren’t just creepy—they’re crawling germ factories. According to research, diseases caused by cockroaches include Salmonella, E. coli, and even parasitic worms. They can also spread bacteria that lead to food poisoning and gastrointestinal illnesses. This type of cockroach disease transmission happens when their droppings, saliva, or even shed skins contaminate your home.

Cockroaches and Allergies
Here’s a lesser-known fact: cockroaches are a major source of indoor allergens. Their droppings, saliva, and shed skins release proteins that can trigger allergic reactions in sensitive people. Cockroach allergy symptoms can range from sneezing and skin rashes to coughing and even asthma attacks. In fact, according to the National Library of Medicine, cockroaches and asthma are closely linked—between 40% and 60% of people with asthma in urban areas are sensitive to cockroach allergens.
How Dangerous Are Cockroaches Compared to Other Pests?
You may be relieved to know that cockroaches aren’t deadly in the same way venomous pests are—there aren’t really “deadly kinds of cockroach.” But don’t let that fool you. Their ability to spread bacteria, worsen asthma, and cause allergic reactions makes them one of the most persistent cockroach health hazards around. Even their droppings can be risky; are cockroach droppings dangerous? Yes—especially for kids, elderly adults, and anyone with respiratory issues.
Cockroaches may not bite often or have venom like some insects, but they’re still dangerous houseguests. They can damage your property, contaminate your food, and put your health at risk. If you’ve spotted these pests—or signs like droppings or egg cases—it’s time to act fast. Fox Pest Control can help eliminate the infestation and keep it from coming back.
Life Cycle of Cockroaches
Cockroaches go through a few main stages in their lives, and while they all have a similar life cycle, there are a few differences between species. Let’s break it down!
1. Egg Stage: It all starts when a female cockroach lays her eggs in a special case called an ootheca. The number of eggs in each case depends on the species, but there are usually between 10 and 40 eggs inside. For example, an American cockroach might lay around 16 eggs in one case, while a German cockroach can lay up to 30. These egg cases are usually tucked away in dark, hidden spots, like cracks or behind furniture, where they’re safe.
After about 2 to 6 weeks, the eggs hatch, but how fast depends on the temperature and humidity. Warm, humid places speed up the process. Some species, like the German cockroach, even carry the egg case with them until the eggs are ready to hatch!
2. Nymph Stage: When the eggs hatch, little cockroaches called nymphs come out. These tiny critters look like mini adult cockroaches but without wings. They’re also light in color and kind of squishy. Nymphs will molt, or shed their skin, several times as they grow. This stage can take anywhere from a few months to a year, depending on the species.
For example, American cockroach nymphs take about 6 to 12 months to fully grow up, while German cockroaches mature much faster, usually in about 2 to 3 months. Nymphs typically molt about 6 to 8 times before becoming full-grown adults.
3. Adult Stage: Once nymphs finish their molts, they reach adulthood. At this point, they have fully developed wings. But don’t expect all cockroaches to be great fliers. For example, while the American cockroach can fly short distances, species like the German cockroach and Oriental cockroach prefer running to flying.
As adults, cockroaches can live anywhere from a few months to a year. The American cockroach can live for up to 1 year, while the German cockroach usually only lasts about 3 to 6 months.
Female cockroaches can start laying eggs soon after they reach adulthood. Since they reproduce so quickly, cockroach populations can grow out of control if you don’t stay on top of it.
Differences Between Species
While most cockroaches follow a similar life cycle, there are a few differences:
- Speed of Growth: Some species grow faster than others. German cockroaches are speedy, maturing in just 2 to 3 months, while American cockroaches take 6 to 12 months to grow up.
- Egg Production: Different cockroach species lay different amounts of eggs. For example, the German cockroach lays 30 eggs in one case, while the American cockroach lays around 16.
- Lifespan: German cockroaches live around 3 to 6 months as adults, while American cockroaches can live up to 1 year.
- Where They Live: Some cockroaches, like the German cockroach, love to hang out indoors, while others, like the American cockroach, prefer living outside but might wander inside if they’re hungry or looking for warmth.
Knowing about the life cycle of cockroaches can help you understand why they’re so hard to get rid of. With their fast growth, high reproduction rates, and ability to hide in tiny spaces, they can take over if you’re not careful. Check out the information below to understand a few more differences between the most common species:
The Most Common Cockroach Species in Homes
Think all cockroaches are the same? Think again. If you’ve spotted one scurrying across your kitchen floor, it’s probably one of just a few usual suspects. Knowing the type of roach you’re dealing with can make all the difference when it comes to control. While there are thousands of cockroach species out there, only a handful are known for invading homes. Let’s break down the most common species, what sets them apart, and how to identify them in your home.
- German Cockroach: Tiny, tan, and fast. These roaches are the top culprit in most indoor infestations, especially in kitchens and bathrooms.
- American Cockroach: Much larger than most cockroaches. You might hear them called “palmetto bugs” in the South.
- Oriental Cockroach: Dark, shiny, and slow-moving, often found in damp areas like basements and drains.
- Brown-Banded Cockroach: Smaller than American roaches, with light bands across their wings. They prefer drier spots—think closets and electronics.
These roaches aren’t just creepy. They’re also tough. Knowing which species is camping out in your cabinets can help you tackle the problem more effectively.
American vs. German Cockroach: How to Tell the Difference
This is the match-up most people are curious about. So, what’s the difference between a German and an American cockroach?
- Size
- German Cockroach: About ½ inch long
- American Cockroach: Up to 2 inches long
That’s a big size gap, and it’s usually the easiest way to tell them apart.
- Color
- German Roaches are light brown or tan with two dark stripes running down their backs.
- American Roaches are reddish-brown with a yellowish halo behind the head.
- Where They Hide
- German cockroaches love kitchens and bathrooms, especially near heat and moisture.
- American cockroaches prefer basements, crawlspaces, and drains, but they can make their way inside.
- Behavior
- German cockroaches breed quickly. Like, really quickly. If you’ve seen one, there are likely dozens more hiding.
- American cockroaches reproduce more slowly but are harder to kill due to their size and strength.
Still wondering how to tell if it’s a German cockroach vs. an American cockroach? Size is your best clue, followed by where you find them.

Oriental, Brown-Banded, and Other Cockroach Lookalikes
It’s not just American and German roaches that sneak into homes. Here’s how a few other species compare:
- Oriental Cockroach vs. American Cockroach
Oriental roaches are darker—almost black—and a bit smaller than Americans. They move more slowly and are usually found near water sources. - Brown-Banded vs. German Cockroach
Brown-banded roaches have light stripes across their wings, not on their heads like Germans. Plus, they hang out in drier areas like closets and ceiling corners. - German vs. Oriental Cockroach
- German roaches are smaller, lighter, and more common indoors. Oriental roaches stick to damp places and are much less likely to be in your kitchen.
Even among roaches, looks can be deceiving. But don’t worry—there’s a cheat sheet coming up next. This quick reference should help with cockroach species identification if you’re unsure what you’re seeing.
Identifying Cockroaches in Your Kitchen
If there are cockroaches in your kitchen, chances are high you’re dealing with German cockroaches. These pests love:
- Warmth from appliances like dishwashers and microwaves
- Moisture from sinks and leaks
- Food crumbs and grease splatters
They’re tiny, fast, and often hide behind cabinets or inside drawers. Spotting even one during the day could mean there’s a much larger infestation hidden away.
Wondering how to identify cockroach species without getting too close? Look for size, coloring, and location. If they’re small and running around your kitchen, they’re probably German. If they’re big and popping up in your basement or near drains, American or Oriental cockroaches could be to blame.
If you’re spotting roaches in your kitchen, bathroom, or basement, it helps to know which type you’re dealing with—but you don’t have to play pest detective on your own. Whether it’s German, American, Oriental, or brown-banded cockroaches, Fox Pest Control has the experience to help you feel comfortable in your home again. Call today for a free inspection and customized treatment plan that fits your needs.
The Roles of Adult Cockroaches
Cockroaches don’t run a tight ship like ants or bees—they’re way more laid-back. While ants and bees have organized colonies with workers, soldiers, and a queen calling the shots, cockroaches are independent operators. They don’t have queens, jobs, or assigned duties. Each cockroach is out there on its own mission to find food, water, and shelter.
Sometimes you’ll see groups of cockroaches hanging out, but that’s more about convenience than teamwork—like crashing the same buffet. They’ll gather in spots with plenty of food or moisture because it’s practical, not because they’re planning anything together. In some species, you might find a bunch of them sharing damp, dark spaces like garbage piles, but it’s all about survival, not cooperation. Cockroaches are basically the lone wolves of the pest world—they just happen to party together when the conditions are right!
Behavior, Diet, and Living Conditions of Cockroaches
Okay, so we’ve learned a lot about cockroaches, their life cycle, and a few cool things about them. But as we shared a bit earlier, there are differences between each species, and there are things to know about each of them. We’re going to go into a little more detail about the top five species so you can know more about what you might be dealing with.

American Cockroach
Also known as: Periplaneta americana
American cockroaches are the largest and fastest roaches you’ll come across. You’ve probably seen them in kitchens, basements, or even restaurants. They’re usually the ones that come to mind when we think “cockroach.” Here’s what you should know about these big guys:
Where did American Cockroaches Come From?
Given their name, you might think American cockroaches would be from the United States, but you’d be wrong. American cockroaches are originally from Africa and were introduced to the U.S. around 1625. Because of global trading, they are now spread worldwide. Even though they’re mostly found in basements, sewers, and large commercial buildings like restaurants and grocery stores, sometimes they invade homes, especially after heavy rain. In places like sewers, their populations can grow to huge numbers—sometimes over 5,000 in a single manhole!
Size and Appearance of American Cockroaches
American cockroaches are pretty big—around 1.5 to 2 inches long, or about the size of a thumb. They can even have a wingspan of up to 3 inches! They’re reddish-brown with a light yellowish, figure-eight pattern on the back of their head. These roaches are fast, able to run up to 3 miles per hour, and they’re good at flying short distances when needed. So, don’t be surprised when they take off!
Habitat and Behavior of American Cockroaches
American cockroaches love warm, humid spots like kitchens, basements, and attics, but their favorite is the sewers. Of course, they hang out in places with food and water, especially at night when they’re most active. While you’ll often find them indoors, they’re not picky—they also like to chill in garbage piles, trees, and mulch outside. They prefer to stay hidden during the day, so they’ll slip into cracks and dark corners until it’s time to come out.
What do American Cockroaches Eat?
These roaches are omnivores, meaning they’ll eat just about anything. Whether it’s food scraps, garbage, glue, cardboard, or even fabric, they’re not picky eaters. This is where that bite force comes in handy! Even though they eat just about anything, they can go for a month without food. They can’t survive long without water though—only about a week! So, you can bet they’re always on the lookout for a water source.
Life Cycle of American Cockroaches
The American cockroach’s life cycle is a bit slower than other roaches, but they make up for it with their long lifespan. Female American cockroaches lay egg cases (oothecae) with up to 16 eggs each and produce about 8 cases in their lifetime, adding up to around 128 offspring.
It takes American cockroaches 6 to 12 months to grow from nymph to adult, which is much longer than other roach species. As adults, American cockroaches live up to a year, longer than most other roaches. Of course, that all comes down to whether a predator catches up to them or not. Their growth and reproduction are influenced by the environment—warm, humid places speed things up, while cooler spots slow them down.
Mistaken Identity
It’s easy to mistake American cockroaches for other big roaches because they look so much alike. Australian cockroaches are often mistaken for American ones, but they’re smaller and have yellow markings on their wings. American roaches are also mistaken for Smokybrown cockroaches, which are just as big but solid dark brown or black.
American cockroaches are often mistaken for palmetto bugs or waterbugs, but these are actually different pests. The term palmetto bug is often used as a nickname for several types of roaches and even beetles, especially in the southeastern U.S. American cockroaches are just one type of roach that’s earned this nickname. Water bugs are aquatic insects which are unrelated to but look a lot like a roach. If you’re not sure which one you’re dealing with, take a closer look at their color and markings—this can help you figure it out. Or, even better, call Fox to figure it out for you!
How American Cockroaches Affect You
So, roaches….these guys are more than just creepy—they can actually carry germs from the trash and sewers, and spread them to your food and kitchen surfaces. They’ve been linked to illnesses like salmonella and E. coli. Plus, their droppings, saliva, and shed skin can make people with asthma or allergies feel worse, especially kids.
Next up, let’s learn about the roaches from down under.
Australian Cockroach
Also known as: Periplaneta Australasiae
Have you ever spotted a big, fast cockroach with yellow on its wings? If so, you might have bumped into an Australian cockroach, also nicknamed “shad roach”. Even though their name makes them sound like they’re only from Australia, they’ve actually spread to warm places all over the world. Let’s take a closer look at what makes these roaches tick, from what they look like to where they like to hang out, and how they could affect your home.
Where Did Australian Cockroaches Come From?
It was previously thought Australian cockroaches originally came from Australia, but now scientists think they came from Africa by hitching a ride on ships carrying slaves. These days, they’ve spread to many warm places around the world, like the U.S., Caribbean, and parts of Asia. They likely traveled with people through trade and travel, making them a common pest in tropical and subtropical areas.
Size and Appearance of Australian Cockroaches
Australian cockroaches are about 1.5 inches long and are reddish-brown with distinct yellow markings on their wings and thorax, which set them apart from other roaches. They also have long, slender bodies and long antennae. Their wings allow them to fly short distances, and they can move pretty quickly on the ground too!
Habitat and Behavior of Australian Cockroaches
These cockroaches love warm, humid places, so you’ll often find them in kitchens, bathrooms, and basements—especially in tropical or subtropical regions. They’re active mostly at night and like to hide in dark, damp spots during the day. If you’re in a warm climate, Australian cockroaches can also be found outdoors, around gardens, garbage piles, or under mulch.
What Do Australian Cockroaches Eat?
Australian cockroaches are omnivores, meaning they’ll eat just about anything! They prefer things like food scraps, decaying organic matter, and plants. They’re especially attracted to sugary or starchy foods, so they might hang out in your kitchen or pantry if there’s a food source. Like other cockroaches, they need water to survive, so they’ll also be drawn to leaky pipes or standing water.
Life Cycle of Australian Cockroaches
The life cycle of an Australian cockroach involves three main stages: egg, nymph, and adult. Females lay their eggs in a protective case called an ootheca, which can hold about 24 eggs. The eggs hatch in about two months, and the nymphs go through several molts as they grow, which can take around 6 months to a year. Once they reach adulthood, they can live for about 1-2 years. Females can lay multiple egg cases in their lifetime, leading to fast population growth in the right conditions.
Mistaken Identity
As we mentioned before, Australian cockroaches are often confused with American cockroaches because they look similar. They’re both large, reddish-brown, and fast movers, but Australian cockroaches have yellow markings on their wings that American cockroaches lack.
Australian roaches are also frequently mistaken for water bugs.
How Australian Cockroaches Affect You
While Australian cockroaches aren’t known for biting, they can still cause problems. Like other cockroaches, they can carry germs and spread diseases like salmonella and E. coli by contaminating food or surfaces. They can also trigger allergies or asthma, especially in kids. So, even though they’re not dangerous in the traditional sense, it’s still a good idea to keep them out of your home!
In short, Australian cockroaches are tough pests that thrive in warm, humid areas. They can be a bit tricky to get rid of, but keeping your home clean and sealing up entry points can help keep them away!

Brown-banded Cockroach
Also known as: Supella longipalpa
Meet the brown-banded cockroach, a tiny indoor pest that spends its whole life inside homes and buildings. Named for the two light bands on their bodies, these roaches are easy to spot if you know what to look for. Let’s dive into what makes these little critters unique and how they might affect your home.
Where Did Brown-banded Cockroaches Come From?
Brown-banded cockroaches are thought to have originated in Africa but they may have come to the US from Cuba, making their home first in Florida around 1903. These little buggers have since spread worldwide, especially to warmer regions. Unlike some roaches that prefer damp areas, these little pests have adapted to drier environments, making them a common nuisance in homes and apartments.
Size and Appearance of Brown-banded Cockroaches
Adult male brown-banded cockroaches are about ½ inch long and have a light brown color with fully developed wings, making them capable of short flights when disturbed or searching for a mate. Females, on the other hand, are a bit shorter and stockier than males. Unlike the males, the females’ wings don’t completely cover their abdomen, which gives them a slightly different appearance. This difference in size and wing length makes it easier to tell males and females apart if you happen to spot them. Despite their small size, both males and females are quick movers and skilled at hiding in tight spaces.
Habitat and Behavior of Brown-banded Cockroaches
Brown-banded cockroaches are unique because they prefer dry, warm areas – preferring temperatures over 80 degrees. They’re sometimes called the “furniture cockroach” because it’s likely you’ll find them in bedrooms, closets, or even inside furniture. They’ll hide during the day in cracks, behind picture frames, or inside electronics (especially when they’re warm!). They’re nocturnal, which means they’re way more active at night, but don’t think that means you won’t see them during the day. When they are out and about, they don’t like light and will scurry away as soon as you flip the switch.
Diet of Brown-banded Cockroaches
These little roaches are omnivores, meaning they’ll eat pretty much anything they can find, including other cockroaches. They’re especially drawn to starchy or sugary foods, but they won’t stop there—they’ll also nibble on things like boxes, drapes, wallpaper, book bindings, and even the adhesive on stamps. If it’s edible to them, it’s fair game!
Life Cycle of Brown-banded Cockroaches
Brown-banded cockroaches have a typical cockroach life cycle: egg, nymph, and adult. Females lay egg cases (oothecae) that hold around 14-18 eggs each, and they’ll glue these cases to hidden surfaces like furniture or walls. It takes about 3-6 months for the eggs to hatch and for the nymphs to grow into adults. Once they’re fully grown, adults live 5-6 months, and each female can produce up to 13 egg cases with 10-18 eggs in each…that’s a lot of baby roaches! This is why a few unchecked cockroaches in your home can become an infestation in no time.
Mistaken Identity
Brown-banded cockroaches are often confused with German cockroaches because of their small size. The easiest way to tell them apart is by looking for those distinct light bands on their bodies, which German cockroaches don’t have.
How Brown-banded Cockroaches Affect You
How They Affect You
While they might be small, brown-banded cockroaches can cause big problems. They can spread germs and bacteria, contaminating food and surfaces. Their droppings, shed skin, and saliva can also trigger allergies and asthma symptoms, especially in sensitive individuals. Plus, their habit of hiding in furniture and electronics makes them tricky to track down and even harder to get rid of.
So, now you know that brown-banded cockroaches are sneaky little pests that prefer dry, warm spots in your home. Keeping things clean, sealing up cracks, and calling in professional cockroach pest control can help keep them out!
German Cockroach
Also known as: Blatella germanica
German cockroaches are considered the most common cockroach species found in homes and buildings worldwide. These pests are small but mighty when it comes to causing trouble. With their quick reproduction and sneaky hiding spots, German cockroaches are experts at making themselves right at home—whether you invited them or not! Let’s dive into what makes these roaches tick and why they’re such a nuisance.
Where Did German Cockroaches Come From?
Despite their name, German cockroaches didn’t necessarily come from Germany. They’re thought to have originated in Southeast Asia, on a tropical island called Borneo and spread through shipping in the spice trade. Because of that, you can find them just about anywhere humans live.
Size and Appearance of German Cockroaches
German cockroaches are small, growing to about ½ to ⅝ of an inch long, and are light brown to tan. They do have fully developed wings, but oddly enough, they don’t use them at all. One of their most recognizable features is the two dark, parallel stripes running down their back, just behind their head. These stripes make them easy to identify compared to other roach species.
Habitat and Behavior of German Cockroaches
German cockroaches love warm, humid places and will eat just about anything they can find. These little scavengers are mostly active at night, sneaking around to look for food, water, and mates. During the day, they hide in cracks, crevices, or other dark, cozy spots. Their flat bodies make it super easy for them to squeeze into tight spaces. If you see them out during the day, it usually means there are a lot of them, or they’re stressed out from things like a lack of food or water.
What makes German cockroaches such a nightmare to deal with? They’re the speed pros at reproducing! Females lay a ton of eggs and even carry them around until they hatch, so most of the baby roaches survive. Plus, these pests grow up fast, and their small size means they can hide just about anywhere. That’s why they’re so good at infesting buildings and tough to get rid of.
There is one thing that keeps German cockroaches from taking over the world, and that is the cold. While they can survive below 59 degrees Fahrenheit, roaches cannot develop from nymphs to adults. However, don’t let that make you complacent. They can hitch a ride into your home on items brought in from other places, especially secondhand or used goods. And most people don’t keep their homes below 59 degrees, so if they do get inside, they will be able to survive and reproduce.
What Do German Cockroaches Eat?
When it comes to food, German cockroaches aren’t picky eaters. They’ll chow down on crumbs, grease, garbage, and even things like soap, toothpaste, and book bindings. They also feed on dead cockroaches and droppings. They prefer dark, hidden spots like cracks and crevices and are most active at night when they search for food. In homes, they’re usually found in kitchens and bathrooms, especially around stoves and refrigerators where food and water are easily accessible. Their ability to survive on almost anything is one reason they’re so hard to eliminate.
Life Cycle of German Cockroaches
German cockroaches reproduce fast—really fast. A single female can lay up to 50 eggs at a time, and those eggs hatch in just a few weeks. The nymphs (baby roaches) mature quickly, reaching adulthood in about 6 weeks. German roaches breed repeatedly, without breaks, and there may be several generations living together at the same time. With this rapid life cycle, a small infestation can turn into a big problem in no time. That’s why it’s so important to tackle cockroaches early before they multiply out of control.
Mistaken Identity
German cockroaches are often confused with Asian and brown-banded cockroaches because of their size. However, brown-banded roaches have light bands across their bodies and don’t have the signature dark stripes that German cockroaches do. Asian cockroaches are strong fliers and have longer, more narrow wings. Also, Asian roaches prefer outdoor banquets, feeding on dead leaves and such.
How German Cockroaches Affect You
German cockroaches are more than just creepy—they can also be harmful. They carry bacteria that can spread diseases like salmonella and E. coli. Plus, their droppings, shed skins, and saliva can trigger allergies and asthma, especially in children. If you see one, it’s important to act fast to keep them from multiplying and causing more problems.
German cockroaches are small but persistent pests that can quickly overrun your home if left unchecked. Keeping things clean, sealing up cracks, and calling in a professional can help keep out these unwelcome guests!

Oriental Cockroach
Also known as: Blatta orientalis
Oriental cockroaches, often called water bugs, are one of the more mysterious members of the cockroach family. Known for their shiny, dark appearance and love of damp places, these pests can cause trouble in homes and businesses alike. While they might not be as speedy or daring as some of their roach relatives, they’ve got their own unique quirks that make them worth learning about.
Where Did Oriental Cockroaches Come From?
Despite their name, Oriental cockroaches didn’t originate in the Orient. They likely came to North America from Russia or North Africa, hitching rides on trade ships centuries ago. Today, they can be found in many parts of the world, thriving in areas with mild, wet climates.
Size and Appearance of Oriental Cockroaches
Oriental cockroaches are easy to recognize with their glossy, black or dark brown bodies. Males have wings that cover about three-quarters of their body, while females have tiny, non-functional wings. The inner part of the wing is thin and fan-like, while the outer part is thicker and leathery. Despite having wings, neither males nor females can fly. Males can also be identified by the styli, small appendages located between their pair of jointed cerci. Their shiny bodies give them a distinct, almost beetle-like look.
Habitat and Behavior of Oriental Cockroaches
True to their nickname “water bugs,” Oriental cockroaches love damp, cool places. Unlike other roaches, they’re not great climbers, so they stick close to the ground. Oriental cockroaches often travel through plumbing pipes inside homes and gather near garbage cans outside, thriving in temperatures between 68 and 84 degrees. They’re more active in spring and summer, and adults are most common during these seasons.
If there gets to be too many of them, overcrowding can push them to migrate to a new, less crowded place. They’re less active indoors than species like German or American cockroaches, but when they do come inside, it’s usually in search of moisture.
What do Oriental Cockroaches Eat?
These roaches aren’t picky eaters. They’ll feed on anything from garbage and decaying organic matter to food crumbs and pet food. They’re scavengers, drawn to moist and decaying environments where food is easy to get to.
Life Cycle of Oriental Cockroaches
Oriental cockroaches begin life as tiny eggs packed into small capsules, each holding about 16 eggs. After about two months, the nymphs hatch and start growing, shedding their skins 7 to 10 times before they become adults. It takes them anywhere from six months to a year to grow up, depending on how warm and humid it is. Once they’re adults, they live for around six months, which gives them plenty of time to multiply and grow their colony.
Unlike other cockroaches, Oriental cockroaches follow a seasonal cycle. Most adults appear in late spring or early summer, but by late summer and fall, their numbers drop due to natural death and new nymphs hatching.
Mistaken Identity
Oriental cockroaches are sometimes confused with other insects because of their dark color and shape. People often mix them up with American cockroaches, but the American ones are bigger and have longer wings. Oriental cockroaches can’t fly and have shorter wings.
They might also be mistaken for water bugs, which are larger and have a more pointed body, but they both like wet areas. Finally, some beetles look similar too, but they’re usually smaller and don’t have the same long antennae or fast movement as cockroaches.
How Oriental Cockroaches Affect You
Oriental cockroaches aren’t just a nuisance—they can pose health risks, too. They’re known to spread bacteria and contaminate food, surfaces, and water with germs picked up from dirty places like sewers and drains. They can also trigger allergies and asthma, especially in children.
Oriental cockroaches might not be as bold or fast as some other species, but their love for damp, dark spots makes them a potential problem in any home or building. Keeping your space dry, clean, and sealed up tight is key to keeping these shiny scavengers at bay!
So now you know a little more about the top five species of cockroaches that you might find in your house. But really, do you want them bunking over, eating your snacks, and giving you the heebie-jeebies? Yeah, not so much. We’re going to get into what signs you need to watch for and how to keep them out, but first, how do they know how to find each other when they’ve found a good place to live?
How Do Cockroaches Communicate?
Well, it’s really gross, but one way cockroaches communicate with each other is by using their feces to send a message. When they leave droppings, they release special chemicals that attract other cockroaches. These chemicals are produced by bacteria living in their guts. So, when a cockroach poops, it’s not just waste—it’s also sending out a signal to others. Here are a few other ways they stay in touch:
Pheromones: These are special chemicals cockroaches release to communicate. When one finds food or something important, it leaves a trail of these chemicals to help other cockroaches find it too. They can also use pheromones to warn others about danger.
Touching with Antennae: Cockroaches have long antennae that they use like little feelers. They’ll tap each other or touch with their antennae to share information, like “there’s food over here” or “let’s go this way.”
Making Sounds: Some cockroaches can make noises, especially when they’re scared or need to warn others. For example, Madagascar hissing cockroaches can make a hissing sound by pushing air through tiny openings in their body. It’s like a little cockroach alarm!
Body Language: They can also use body language, like moving their wings in certain ways to communicate with other cockroaches. This can be part of their mating ritual or a way to show they’re feeling threatened.
So, while cockroaches may not talk the way we do, they’ve got plenty of ways to share info and stay in touch with each other!
Signs of a Cockroach Infestation
If you’re wondering whether you have a cockroach problem, here are some signs to look out for:
Seeing Roaches: The most obvious sign! If you spot cockroaches during the day, it could mean you have a larger infestation, since they tend to come out at night. German cockroaches, in particular, are nocturnal but might be spotted in the light if their numbers are high.
Droppings: Cockroach droppings look like tiny, dark pepper-like specks. You might find them in places like behind appliances, in cabinets, or along walls. A lot of droppings could mean there’s a lot of roaches around.
Unpleasant Odor: Cockroaches can give off a musty, oily smell, especially if there’s a large population. If you start noticing an odd, stale smell in your home, roaches might be the cause.
Egg Casings: Roaches lay eggs in brown, capsule-shaped cases called oothecae. If you find these, especially in hidden or dark places like cabinets or cracks, it’s a sure sign they’re living nearby.
Damaged Items: Cockroaches sometimes nibble on food, paper, leather, and even fabric. If you notice unusual damage to stored items or food packaging, it could be the work of these pests.
These are just a few of the signs of a cockroach problem. Learn more about the signs and what you can do about them here.

What You Can Do About Cockroaches
Along with professional cockroach control, there are plenty of ways you can help reduce the cockroach population in your home. Start by cutting off their access to water, food, and shelter. Seal cracks in floors and walls where roaches can sneak in and fix any leaky pipes and keep damp areas as dry as possible.
Next, tackle their food sources. Store all food, even in cabinets, in airtight containers, and make sure trash cans have tight-fitting lids. Clean up dirty dishes right away, wipe up spills, and sweep up crumbs from counters, tables, and floors. Don’t forget about your pets—avoid leaving pet food out and clean their bowls regularly.
Finally, focus on cleaning and organization. Vacuum and mop floors often, and don’t neglect those hidden spots around and under furniture you rarely move—give those areas a good cleaning at least once a year. Declutter storage spaces like closets, shelves, and drawers to eliminate hiding spots. By following these steps, you can make your home way less inviting for these pesky intruders!
