American Roaches Identification Guide

Physical Characteristics

American roaches are reddish-brown in color with a yellowish figure-eight pattern behind their heads. They are the largest common roach species found in homes, often reaching up to 2 inches in length. Their long antennae and fully developed wings allow them to glide short distances, though they are more commonly seen running. These roaches prefer warm, humid environments and are often found in basements, crawl spaces, and kitchens.

Common Species

Periplaneta americana (American Cockroach)

American Roaches Behavior and Biology

American roaches thrive in warm, damp areas such as sewers, drains, and basements. They are omnivorous scavengers, feeding on decaying organic matter, food scraps, and even paper or fabric in extreme cases. These pests reproduce quickly, with a single female capable of producing over 150 offspring in her lifetime. Their nocturnal nature makes them more active at night, when they search for food and moisture sources.

How We Treat for American Roaches

When treating for American roaches, our technicians focus on inspecting basements, crawl spaces, and other damp areas for signs of activity such as droppings or live roaches. Our process includes:

  • Inspection: Identifying entry points, moisture issues, and harborage areas.

  • Treatment: Applying repellent and non-repellent insecticides inside and outside the home, targeting cracks, crevices, baseboards, and potential entry points.

  • Moisture Control: Recommending steps to reduce humidity, fix leaks, and seal cracks around pipes and drains.

  • Ongoing Prevention: Regular maintenance and preventative treatments to keep American roach populations under control.
