German cockroach (Blattella germanica)
German cockroaches are the main indoor kitchen and bathroom species in Central Florida homes and multifamily buildings. They stay close to food, water, and warm appliances, and populations can build quickly once a few hitchhikers settle in cabinets or wall voids. UF/IFAS treats this species as the structural cockroach of greatest concern statewide.
- Where found
- Kitchens, bathrooms, break rooms, and other warm indoor spaces with crumbs, grease, or moisture. Common under sinks, behind dishwashers and refrigerators, inside cabinet hinges, and along appliance kickplates.
- How to recognize
- Adults are about 1/2 to 5/8 inch long, light brown to tan, with two dark parallel stripes on the pronotum (the shield behind the head). They rarely fly. Egg cases are carried by the female until near hatch.
