What kinds of cockroaches live in Indiana?
Well, you may be surprised at how many different types there actually are! These nocturnal insects are common but can be hard to find.
Cockroaches prefer to stay hidden during the day and can sense our vibrations at night. So they quickly dash away before they are even discovered. Cockroaches can run really fast, up to 11 inches per second! That would be like a human running 93 miles an hour!
One tip to know, if you see a cockroach during the day, there may be more that you don’t see and you may have an infestation. So please call an exterminator for help.
This article will be looking at 6 COMMON cockroaches in Indiana.
#1. German Cockroach
- Blattella germanica
- Males are tan or pale brown, with two dark streaks on their heads.
- The abdomen is slender and tapers down, with a yellowish underside.
- Females are darker brown, and their abdomens are broader.
These cockroaches are significant year-round pests in Indiana.
You would think from its name that the German Cockroach is from Germany; however, it actually came here from Southeast China. These cockroaches are sensitive to the cold, which is probably from their origin in warm climates.

The German Cockroach comes out at night to search for food and water and will quickly dash away if you turn on a light or disturb them. They are plant and meat scavengers. This cockroach is attracted to meats, starches, sugars, and fatty foods. Unfortunately, if they can’t find food, they may eat household items such as soap, glue, and toothpaste.
They will invade houses, apartments, restaurants, hotels, hospitals, and other institutions. During the day, this cockroach hides out and occupies tight spaces around refrigerators, stoves, sinks, and in the walls. So it is difficult to know if you have a cockroach problem.
If you EVER see a German Cockroach during the day, this may indicate that you have a severe infestation.

#2. American Cockroach
- Periplaneta americana
- Shiny, reddish-brown wings, paler neck with two darker reddish-brown blotches in the center.
- Short wings, males’ wings extend beyond their abdomen.
- Also known as the Ship Cockroach, Kakerlac, and Bombay Canary.
The American Cockroach has one of the largest body sizes of ANY cockroach in Indiana. It is also considered one of the fastest running insects. Surprisingly, they are weak fliers.
Believe it or not, American Cockroaches are native to Africa and the Middle East. These cockroaches were brought over hundreds of years ago on ships.
Adults are active all year-round in moist and warm locations, like inside your house! These cockroaches are mostly commercial pests, infesting restaurants, supermarkets, bakeries, warehouses, and shipyards.

Unfortunately, they don’t stop there. These cockroaches are frequently found in homes and apartments because they come up through the sewage and plumbing systems or air ducts. You can find them in basements, crawl spaces, and cracks in foundations.
These cockroaches are not picky eaters. This species will eat beer, leather, hair, flakes of dry skin, fermenting foods, starch from book bindings, and dead animals, including other cockroaches. They eat almost anything they walk on!
The American Cockroach has odorous secretions that can alter the flavor of food, and if there is a high population of them, you will be able to smell it.
This cockroach can also pick up disease-causing bacteria like Salmonella on their legs and deposit it on other food that they walk on. This can cause food poisoning or infections. In addition, house dust that contains cockroach parts or feces can trigger an allergic reaction and asthma in certain people.

#3. Oriental Cockroach
- Blatta orientalis
- Shiny dark reddish-brown to blackish-brown.
- Males’ wings cover three-fourths of their abdomen while females have short, almost non-existent wings.
- Also known as the Waterbug or Black Beetle.
Oriental Cockroaches are also called Waterbugs because they prefer dark, moist places. They are sluggish, flightless, and are poor climbers.

This species is often found in sewers, drains, damp basements, porches, or other damp locations. Outside they are typically located under mulch, bushes, leaf litter, and woodpiles. Look for them eating decaying plants, starchy human scraps, and animal matter.
The Oriental Cockroach is a major household pest. This species creates a strong smell and is considered one of the dirtiest cockroaches in Indiana.
The Oriental Cockroach can transfer bacteria and viruses from their legs to food, dishes, utensils, and countertops. This species spreads Salmonella, E. Coli, Dysentery, and food poisoning. So if you see them in your house, call an exterminator right away!
#4. Brown-Banded Cockroach
- Supella longipalpa
- Tan to light brown and has two light-colored bands across the wings and abdomen (which makes them look broken.)
- Males’ wings cover the abdomen and are more slender.
- Females are darker with shorter wings, and they have broader abdomens.
The Brown-banded Cockroach is the smallest in Indiana.
Interestingly, this species doesn’t need as much moisture as the other cockroaches. This fact is important because it means that they can inhabit places in your house that other cockroaches don’t dare enter. Typically, you can find them hiding in appliances and cabinets, but they can be anywhere in your home, such as the living room or the bedroom.
These cockroaches tend not to be found in the daytime because they avoid the light. So think of them as little gremlins!

The Brown-banded Cockroach will eat anything and everything, including any foods, sewage, boxes, drapes, books, and wallpapers. So basically, they have a seafood diet; if they see it, they eat it. : )
Unfortunately, this insect can cause many challenges for humans because they carry microorganisms and spread pathogens.

#5. Pennsylvania Wood Cockroach
- Parcoblatta pensylvanica
- Males are dark brown, sides of the thorax (between head and abdomen) and front half of wings are yellowish. Wings are fully developed and longer than the abdomen.
- Females are dark brown, with short and useless wings.
- Also known as the Pennsylvanian Cockroach.
After dark, you can usually find this cockroach in timbered-covered areas, on tree trunks, and in lower branches of oaks and elms. They are also found in piles of wood, tree stumps, and hollow trees.

The Pennsylvania Wood Cockroach gets inside your house typically from hitching a ride inside the firewood you brought into your home.
Fortunately, this species does not like to live with other cockroaches. Therefore, they are not contaminated and usually will not make you sick.
Pennsylvania Wood Cockroaches like cooler temperatures!
In addition, this species can only survive indoors for a few weeks because it is too dry and they prefer to eat decaying organic matter such as compost, dead plants, or manure. A cockroach that has to stay outside is the best cockroach in my opinion!
However, check out this video where these cockroaches can be pets if you want to provide food and water for them.
#6. Smoky Brown Cockroach
- Periplaneta fuliginosa
- Shiny and dark brown mahogany all over.
- In both sexes, their wings extend past their abdomens.
The Smoky Brown Cockroach prefers to live outdoors in piles of leaves and by drains or sewers. They eat a wide variety of organic or decaying matter, but like other cockroaches, they are scavengers. So that means they will eat whatever they can find to survive.

This species tends to lose moisture faster than other cockroaches in Indiana.
As a result, they require water every two to three days.
The Smoky Brown Cockroach prefers warmer climates and can’t tolerate the cold. Unfortunately, they may come indoors to look for food during cooler weather.
