Eliminate food sources by keeping the kitchen and other areas of the home free of food scraps. Clean up the kitchen after each meal and store food in tightly sealed metal, glass, or heavy plastic containers. Empty household garbage and pet litter regularly. Clean up water puddles or moist areas around the kitchen, basement, and other infested areas. Plug cracks around baseboards, shelves, cupboards, sinks, and pipes with putty or caulk.
