Seal cracks and other openings to the outside.
Use weather stripping on doors and windows.
Look for other methods of entry, such as from items being brought into the building, especially appliances, furniture, and items that were recently in storage. Inspect food deliveries before putting them in kitchens.
Look for egg cases (oothecae) glued to undersides of furniture, in refrigerator and other appliance motors, boxes, and other items. Remove and destroy any that you find.
Locate and seal cracks inside the treatment area where cockroaches can hide.
Trim shrubbery around buildings to increase light and air circulation, especially near vents, and eliminate ivy or other dense ground covers near the house, as these may harbor cockroaches.
From around the outside of buildings remove trash and stored items such as stacks of lumber or firewood that provide hiding places for cockroaches.
Consider keeping a layer of gravel about 6 to 12 inches wide around the perimeter of buildings.
