Clean stoves and ovens after use. Wipe counters clean with soap and water or a disinfectant, according to school policy. Make sure trash is removed daily. Fix plumbing leaks and other moisture problems. Do not let water stand in air conditioning or refrigerator drip pans.
Place dumpsters away from the building to minimize opportunities for pests to enter the building.
Block possible entry points for rodents and other pests. Track cockroach populations by using small sticky traps or monitoring traps which contain no pesticide. Rats and mice should be trapped rather than baited. Pesticide sprays should only be used in classrooms as a last resort. Schedule pesticide applications for unoccupied periods so that the affected area can be well ventilated before occupants return.
