Cockroaches in Air-Conditioned and Cool Rooms: Why They Linger

Cool rooms don't stop cockroaches. They look for warmth, moisture and food nearby.

Cabinets, appliances and drains are common hideouts.

The short answer

In air-conditioned spaces, cockroaches shelter near warm motors, electrical equipment, condensation lines and kitchen areas. Seal gaps, clean spills, fix leaks, keep food covered and use gel baits placed by a professional. Check around AC drain pipes and behind appliances.

Where they linger

• Behind fridges and microwaves.
• Around AC drain pipes and condensation.
• In cupboards under sinks.
• Near electrical panels.
