Key point in one sentence: The most direct way to stop bed bugs hitching a ride home in your luggage is to follow the Food and Environmental Hygiene Department’s public guidance: hot washing, freezing, vacuuming and sealing cracks.
To reduce the chance of bed bugs (commonly called “stink bugs” or woodlice) following your luggage home, the most direct approach is to follow the Food and Environmental Hygiene Department (FEHD) and Centre for Health Protection (CHP) public guidance: use hot washing, freezing, vacuuming and sealing cracks for physical control, and inspect your luggage carefully when you return to Hong Kong. This site does not exaggerate a “city-wide outbreak” and does not promote any particular pest control company.
The official “ten tips”: actionable points (based on the FEHD PDF)
1. Wash bedding and clothing in hot water at 60°C, then dry them or iron them at high temperature. 2. For babies’ bedding, rely mainly on physical control. 3. Items that cannot take high temperatures should be sealed and placed in a freezer at about −18°C for about 24 hours. 4. Use hot air or steam into cracks (beware of burns). 5. Diatomaceous earth must be used with a mask, goggles and gloves, and cleaned up afterwards. 6. Clean and vacuum regularly. 7. Inspect bedding and clothing. 8. Keep things dry. 9. Avoid second-hand furniture. 10. Fill gaps in wallpaper and furniture.
Travelling and airport publicity: how to reduce the risk of bringing bed bugs home in your luggage
The FEHD has handed out bed bug prevention leaflets to travellers at Hong Kong International Airport, and reminded airlines and the Airport Authority to pay attention to environmental hygiene. When travelling, use sealed bags; when checking in, inspect mattress seams and keep luggage off the floor; when returning to Hong Kong, check the compartments of your luggage, and wash any suspect clothing in 60°C hot water according to how heat-resistant it is.
Physical egg removal and sealing cracks
Bed bug eggs are often stuck in cracks. The effective approach is to seal cracks, use heat or freezing on textiles, vacuum, and apply steam into cracks, then assess whether professional help is needed. Bug bombs or foggers are not recommended as the main method, as they can drive the bugs to scatter.
For Hong Kong readers
Treat landing at the airport as the start of a “return check”: keep luggage off the floor, check the compartments, and wash clothes at the official temperatures. In public housing and subdivided flats, where there are many cracks, sealing cracks and not dumping second-hand mattresses carelessly often matter more than spraying a few more times. For bite symptoms, see the bed bug bite symptoms guide; for prices, see the bed bug extermination price guide. Airport leaflet distribution is preventive education — it does not mean there is a city-wide outbreak right now.
