German cockroaches
The German cockroach (Blattella germanica) cannot survive away from people, which makes it the roach of kitchens and bathrooms. UF/IFAS calls it the most serious structure-invading cockroach of apartment buildings, condominiums, restaurants and single-family homes. It rides in with boxes, backpacks and purses from infested places. Each egg case holds 30 to 40 eggs and the life cycle takes about 100 days. Spraying alone is the least effective response; baits and sanitation work together.
