Summer is Peak Pest Season! Hong Kong's Guide to Pre-Summer Pest Prevention
Hong Kong's summer (May to October) sees temperatures of 30–35°C with relative humidity exceeding 80% — ideal breeding conditions for pests. Preparing prevention measures before summer begins can significantly reduce the chance of pest problems.
April to May: Pre-Summer Preparation
Full house spring clean: Clean all kitchen corners and behind the refrigerator; clear clutter and cardboard boxes from under kitchen counters (cockroach hiding spots); clean all gaps in kitchen and bathroom. Structural inspection: Check and seal pipe gaps under the kitchen sink with silicone; check window frame and door frame seals; ensure all drain openings have pest screens. Preventive pest treatment: Booking a whole-home preventive pest treatment before summer offers the best value for money of any time of year.
During Summer: Ongoing Prevention Measures
Kitchen: Clean hob and countertops every evening; store food in sealed containers; dispose of kitchen waste daily. Mosquitoes: Inspect and clear standing water weekly; change water in plant saucers regularly; check window screens for damage before bed. General hygiene: Wash bins weekly; avoid eating outside the kitchen; clean air conditioner filters regularly.
