Cockroaches do not need large amounts of food to survive, especially in the presence of water. Furthermore, food sources can compete with cockroach baits, decreasing their effectiveness. Elimination of food sources includes:
• Store and dispose of garbage properly. The highest concentration of cockroaches in a home is usually around the garbage can and around the refrigerator.
• Seal garbage can lids to prevent cockroaches from accessing food sources. Also, keep garbage areas clean by disinfecting and removing debris frequently.
• Dump sink strainers frequently to prevent food build up.
• Wash dishes immediately after use. Dishes left unwashed are a major source of food for a kitchen infestation.
• Keep kitchen appliances such as toasters, toaster ovens, microwaves, stoves, ovens, and refrigerators free of crumbs and other food debris. In addition, clean the areas around these appliances.
• Reseal all food after opening or store in the refrigerator.
• Seal pet food tightly. Do not leave food and water out all the time. Train dogs to eat food when it is first placed in the bowl.
• Regularly vacuum or sweep under and around furniture where people eat, such as the dining room table. Vacuuming can also remove cockroach egg cases that will not be killed by insecticides. Remember to promptly dispose of the vacuum cleaner bag in an outdoor container.
