Household sprays when applied directly to hiding places will flush and kill cockroaches. Insecticide basit stations can also kill cockroaches. For severe or persistent infestations, a pest control professional will provide the most cost effective control. In rare cases German cockroaches will move from one building to another, however, infestations are usually initiated through the introduction of infested materials. Inspect for cockroaches and their egg cases in sacks, cartons, boxes, used appliances and furniture, etc., brought into the home.
Sanitation is critical in cockroach control.
Thoroughly clean areas beneath cabinets, sinks, stoves, refrigerators, etc. as well as cupboards, pantry shelves and food storage bins. Clean up spilled foods and liquids. Avoid leaving scraps of food on unwashed dishes and counter tops overnight. Keep food in tightly sealed containers, rinse cans and bottles before putting in the trash, and transfer garbage outdoors into cockroach-proof receptacles away from the house. Leftover pet foods should not remain in the feeding dish overnight.
