German Cockroaches
Light brown, about half an inch long, with two parallel dark stripes behind the head. The most problematic species — they live and breed inside, prefer kitchens and bathrooms, and reproduce rapidly. A small German roach problem can escalate quickly.
American Cockroaches
Reddish-brown, 1.5–2 inches long, with a yellowish figure-eight marking behind the head — also called palmetto bugs. They prefer moist environments such as sewers, drain areas, and utility spaces. They come inside when outdoor conditions are hot or wet.
Smoky Brown Cockroaches
Dark brown to mahogany, about 1.5 inches long, with uniform dark coloring. Primarily an outdoor and perimeter species in Central Texas. They enter through gaps in rooflines, soffits, and attic vents and are often found in garages.
Homeowner Steps
For German roaches: eliminate moisture under sinks, clean behind appliances, and use bait gel at active sites. For American and Smoky Brown: address outdoor conditions and seal entry points. Both benefit from professional service.
