When you find bed bugs in your mattress, the first instinct is often: throw it out! But dragging an infested mattress through the corridor and dumping it at the refuse collection point lets bed bugs drop off along the way — infesting your entire floor or even the whole building. You won’t just fail to solve your own problem; you’ll drag your neighbours into it too.
Before dumping: Do you really need to?
Often the mattress doesn’t need to go: a light infestation can be handled by encasing the mattress in a bed bug cover, trapping the bugs inside (the cover must stay on for over a year); high-temperature steam treatment of the mattress surface and seams, combined with vacuuming, resolves many cases; dumping the mattress doesn’t solve the problem — if bed bugs remain in the bed frame and wall cracks, a brand-new mattress will get infested too.
Correct disposal in 5 steps
1. Vacuum first to reduce live insects, then immediately seal the vacuum bag and take it outside. 2. Seal and wrap the whole mattress — use large plastic bags, a mattress disposal bag, or stretch wrap to completely seal it, taping all openings shut. This is the most important step. 3. Label it: stick a note saying “Bed bugs — do not take” so nobody picks it up. 4. Take the shortest route from your flat to the refuse point; coordinate with building management. 5. Contact building management — in Hong Kong, bulky furniture disposal normally requires arranging a time at the designated bulky waste collection point; don’t leave it in the corridor.
Before bringing in a new mattress
Thoroughly inspect the bed frame — take it apart and check joints and crevices; check wall and floor cracks and steam-treat if needed; encase the new mattress in a bed bug cover right away; monitor for 2–4 weeks to confirm no new bites.
Never do these
Don’t drag an unwrapped infested mattress through the corridor; don’t leave it next to the refuse point for someone to pick up; don’t assume dumping ends the problem without inspecting the room; don’t spray insecticide in the corridor or stairwell (it scatters bed bugs into neighbours’ flats).
