Physical Characteristics

Cockroaches vary slightly in appearance depending on the species, but they share a few defining traits. Most cockroaches are oval-shaped with a flat body, long antennae, and six legs that allow them to move quickly. They are also characterized by prominent cerci, tail-like appendages located at the rear of their bodies. Many species range in color from light brown to black, though some species have unique markings or patterns.

Common Species of Cockroaches in Georgia:

German Cockroach (Blattella germanica)

German cockroaches are one of the most common household pests. They are typically light brown or tan with two dark parallel stripes running lengthwise down their thorax. Measuring between ½ to ⅝ inches in length, German cockroaches prefer warm, humid environments and are largely found in kitchens and bathrooms.

American Cockroach (Periplaneta americana

American cockroaches are the largest of the common indoor species, growing up to 2 inches in length. They are reddish-brown with a yellowish border around their head. Unlike other cockroaches, this species is often found in basements, crawl spaces, and sewer systems.

Oriental Cockroach (Blatta orientalis)

Also known as water bugs, Oriental cockroaches are dark brown or black and have a shiny, almost greasy appearance. They are slightly smaller, averaging about 1 inch long, and are often found in damp areas like basements, drains, and leaky pipes.

Brown-Banded Cockroach (Supella longipalpa)

This smaller species is only about ½ inch long and is easily identified by the light brown bands that run across their wings and abdomen. Brown-banded cockroaches are less dependent on moisture and can be found throughout the home, especially in living rooms and bedrooms where they hide in furniture or behind picture frames.

Signs of a Cockroach problem

Even if you don’t spot cockroaches directly, there are several signs that can indicate their presence in your home. These include droppings that resemble coffee grounds or black pepper, a musty or oily odor, shed skins, egg casings, and smear marks along walls or surfaces. Pay attention to these clues, as they often reveal hidden infestations.

Cockroach droppings resemble coffee grounds or black pepper. Larger species, like the American cockroach, leave cylindrical droppings with ridges.

Cockroach egg cases, or oothecae, are capsule-shaped and vary in color from light brown to dark brown. They are usually found near food sources or hidden away in cracks and crevices.

Cockroaches emit an unpleasant, musty odor that becomes more pronounced with larger infestations.

Cockroaches molt several times as they grow, leaving behind discarded skins that may collect in concealed areas.

You may notice smear marks on walls, floors, and other surfaces, especially near water sources, left by cockroaches scurrying through damp areas.
