Use this guide on the types of cockroaches found in PA to help you identify your invader.

Types of Cockroaches in PA

German CockroachesGerman cockroach

German cockroaches are approximately 1/2″ to 5/8″ long. They have wings but rarely fly as they prefer to run. They have oval-shaped bodies with six legs.

German cockroaches tend to crowd together, so you might see brown spotting left in areas where they congregate. This type of cockroach protects its egg cases, and the females carry the eggs until right before they hatch. During this time, the females tend to stay hidden, so don’t rely on spotting one to identify your infestation.

Oriental CockroachOriental Cockroach

This type of cockroach ranges from 1″ to 1-1/4″ in length—nearly double a German cockroach! They are dark brown to reddish-brown. The males have wings but are unable to fly.

You are most likely to find this type of cockroach outside in May, June, and July when the adults are most active. They tend to be much slower than other types of cockroaches.

American CockroachTypes of Cockroaches in PA: Adult American Cockroach

You won’t miss an American cockroach! Growing 1-1/2″ to 2″ in length, this is one big bug. They have reddish-brown wings and figure-eight markings on their thoraxes. This cockroach is also called a water bug or palmetto bug.

This cockroach is quick, so don’t be surprised if you see one scurrying into the dark. They leave behind droppings that are often mistaken as mouse droppings, so you might not know at first which unwelcomed pest is infiltrating your space. Another clue to an American cockroach infestation is a musty smell caused by pheromones. If you have a sensitive nose, you might pick out the unpleasant odor.

Brown-banded CockroachJuvenile brown banded cockroach isolated on white floor.

These light brown cockroaches grow to be approximately 1/2″ in length (smaller than other varieties) and have fully developed wings. As the name suggests, they have two distinctive brown bands along their wings and abdomens.

This type of cockroach is often found lurking in your kitchen cabinets and bathrooms. It has a long lifespan of 206 days, allowing the pest to reproduce nearly exponentially. Because of its small stature, the brown-banded cockroach can be harder to spot.

An Occasional Visitor: The Smokybrown Cockroachsmokybrown cockroach

While typically found in southeastern states, the smokybrown cockroach sometimes makes its appearance in Pennsylvania. This cockroach grows to be 1-1/2″ in length. They are a dark mahogany brown color. This type of cockroach is a strong flier with wings that extend beyond its body.

This cockroach is often found outdoors, searching for food at night. If they come inside, you are most likely to find them in your basement.
