Key point in one sentence: In public housing and tenement buildings, bed bugs crawl between flats, so treating a single flat can never finish the job; the real solution is building-wide integrated control: report it to the estate office and treat neighbouring flats at the same time.
Once bed bugs (also called “stink bugs” or woodlice) appear in public housing, tenement buildings or old subdivided flats, relying on one household to spray on its own or hiring pest control once is often not enough: the bugs can move back and forth through luggage, second-hand furniture, discarded mattresses and corridor cracks. This article draws on reporting from 2023 and does not present this as a new 2026 policy or a city-wide outbreak.
Earlier reporting: why they come back after you treat your own flat
Ta Kung Wen Wei reported that a public housing resident suspected a neighbouring flat of hoarding clutter and luggage, after which nearby flats were bitten one after another; scholars said a bed bug problem is not only a matter of personal hygiene, but also a matter of building-wide public hygiene. The above reflects reporting and proposals at the time; Hong Kong has no equivalent law requiring the whole building to be notified.
The Housing Department’s public response: how to seek help
When a resident seeks help, the estate office will look into the situation, remind residents about hygiene, and hand out FEHD leaflets; where a resident cannot handle the problem alone, the office may help or make a referral depending on the circumstances. Bed bugs on their own do not automatically mean points will be deducted; do not dump a suspected mattress in the corridor uncovered. In tenement buildings, notify the owners’ corporation or management office and keep a record.
Building-wide integrated control: a coordination checklist you can act on now
1. Notify the estate office or management office immediately. 2. Neighbours on the same floor voluntarily check mattress seams and rust-coloured spots together. 3. Wash bedding in 60°C hot water, seal and freeze items, vacuum and seal cracks. 4. Seal furniture before discarding it; don’t dump it uncovered. 5. If several flats have recurring infestations, consider a professional assessment and compare written quotations from more than one company.
For Hong Kong readers
If you live in public housing and suspect a neighbouring flat or the corridor has bed bugs, go to the estate office and leave a record as soon as possible, and treat your own bed at the same time. If you live in a tenement building or subdivided flat, notify the management office or owners’ corporation, and never throw a mattress into the corridor. This article is based on earlier reporting plus steps you can take now; it does not mean there is a new statutory building-wide control regime in 2026.
Frequently asked questions
Is treating only my own flat enough? In high-density buildings, bed bugs are more easily brought back in, so you should notify the management.
Will one fogger do the job? Foggers are not recommended as the main method; they should be combined with washing, vacuuming and sealing cracks.
