China Four Pests Prevention Checklist

Mosquito: Tip over and drain all standing water containers — plant pot saucers, buckets, old tires, discarded bottles — inspect weekly

Mosquito: Install window screens and screen doors, check for holes; use bed nets at night — physical protection before chemical control

Mosquito: For unavoidable standing water (rain wells, water features), add Bti granules — safe for people and pets, kills only mosquito larvae

Cockroach: Wipe kitchen counters daily, remove all food residue and grease; take out trash every night; store all food in sealed containers — denying food is step one of cockroach control

Cockroach: Seal plumbing penetrations, baseboard gaps, and cabinet bottom cracks with caulk or steel wool — block cockroach entry and travel routes

Cockroach: Apply cockroach gel bait in pea-sized dots under cabinets, behind appliances, along baseboards — 3-4 dots per meter, use continuously for 2-3 weeks

Rodent: Inspect exterior walls for all gaps larger than 6mm (pencil thickness admits mice) — stuff with steel wool first then seal with caulk — the single most critical rodent prevention step

Rodent: Install door sweeps keeping gaps under 6mm; store all food including pet food in sealed hard plastic or metal containers

Rodent: Place glue boards or snap traps along wall edges, under cabinets, and in garage corners — rodent runways follow walls; peanut butter is the best bait

Fly: Take out kitchen waste daily with tightly sealed bins and wash bin interiors regularly — flies lay eggs on garbage, hatching within 24 hours

Fly: Install window screens and screen doors; commercial kitchens can add air curtains or UV fly traps — physical barriers are ten times more effective than spraying

Fly: Clean up outdoor pet waste and fallen rotting fruit promptly; keep drainage ditches and septic tanks sealed — these are the primary fly breeding sites
