Allow the spray application to dry before replacing the food items. Be sure to remove and spray all drawers as well as the inside of the cabinets. Use prevention recommendations to prevent further infestations. Consult the County Extension Office for recommended chemical controls. Some insects, like flies , do not normally infest a food, but can still carry bacteria to the food by coming in contact with it.
Flies are an even greater threat to human health than cockroaches.
Control flies by making sure windows and doors are properly closed or screened. Keep flies away from garbage or other things that are close to the kitchen or food preparation area. Some types of ants are drawn to sweet foods, while others prefer greasy foods. Control ants by immediately cleaning up all food scraps and spills, storing food in sealed containers, keeping fruit in the refrigerator, washing dirty dishes and keeping countertops clean. It may be necessary to caulk around windows and doors, provide adequate screening, and reduce outdoor sites where ants have colonies.
