A
Spray insecticide daily
-
B
Maintain the physical integrity of the facility — seal all gaps, cracks, and openings 1/4 inch or larger; ensure doors self-close and door sweeps seal completely; maintain window screens; keep dumpster areas clean; this physical exclusion approach prevents entry without relying on pesticides in food areas

C
Place poison bait in food prep areas

D
Allow a facility cat to roam the kitchen
Why this is the answer
INTEGRATED PEST MANAGEMENT (IPM) prioritizes PREVENTION over chemical treatment: PHYSICAL EXCLUSION: Seal cracks and gaps (cockroaches enter through gaps as small as 1/16 inch; rodents through 1/4 inch); door sweeps on all exterior doors; self-closing doors; screens on windows and vents; steel wool or cement in pipe openings; SANITATION: Eliminate food and water sources — clean up spills immediately; store food in sealed containers; empty trash frequently; clean under and around equipment; DUMPSTER MANAGEMENT: Dumpsters away from building; lids closed; area clean; PESTICIDE LAST RESORT: Only licensed pest control operators should apply pesticides in food facilities; no pesticides in food areas; targeted baits in enclosed bait stations; document all pest control services. Detecting and addressing entry points is more effective than responding to infestations with chemical treatment.
