Wasp Nest in Hong Kong: Who Removes It, and What Not to Do
Quick answer
Hong Kong splits this cleanly by location. For nests in public places (streets, parks and the like), the Food and Environmental Hygiene Department (FEHD) provides a wasp removal service. But residential premises with a management company, and all private non-residential premises, fall outside FEHD's service — removal has to be arranged by the management company or the owner. In other words: a nest outside your window, on your roof or in your garden is a management-office or pest-control-company matter, not something to wait on the government for. Generally speaking, nests are largest and most aggressive from late summer into autumn (roughly August to October) — the earlier you deal with one, the safer it is.
Step one: who do you report it to?
- Nest in a street, footpath, park or other public place → call 1823, which refers it to FEHD.
- Nest in a housing estate's common area (podium, external wall, corridor window) → notify the management office — residential premises with a management company are its responsibility to arrange.
- Nest on your own private area (eaves of a village house, private garden, on top of an air-conditioning unit, balcony) → the owner arranges professional removal directly.
- Not sure who's responsible? → take a photo and report it to the management office first; if they say it's not theirs to handle, then arrange a pest control company yourself.
Why not remove it yourself?
Three reasons — this is our own safety advice, not a substitute for professional handling:
- Swarm defence — a disturbed nest can empty out and attack as a group. Poking it with a bamboo pole, using fire, or spraying insecticide at it through a window are all effectively declarations of war — and you have no protective gear.
- Height risk — most nests are under eaves, in trees, or high on an external wall. Dodging wasps while standing on a ladder is a double hazard.
- Removing the nest isn't the whole job — leave returning worker wasps and whatever made the spot attractive for nesting unaddressed, and a new nest often goes up in the same place quickly.
If you're stung: a small number of stings can usually be managed with a cold compress and watching for reaction. But if you're stung multiple times, or you develop breathing difficulty, facial swelling, dizziness or other signs of an allergic reaction, see a doctor immediately.
When is it most dangerous? A rough timeline
Generally speaking, a queen starts building in early spring, when the nest is small and lightly populated — risk and removal cost are both at their lowest then. As the colony grows over summer, by roughly August to October the nest reaches its largest size and its most defensive. So if you spot a palm-sized nest in July, don't "wait and see" — two months on it could be basketball-sized with hundreds of wasps in it.
Professional removal process and quote factors
Professional removal generally involves: an on-site assessment (wasp type, nest location, height, evacuation area) → timing the job (usually after dusk once the colony has returned to the nest) → applying treatment or relocating the nest in full protective gear → clean-up and advice on preventing a rebuild. Pricing mainly depends on height and accessibility (low eaves at ground level versus scaffolding or rope access), nest size, and location sensitivity (school or restaurant frontage, for example).

Frequently asked questions
Will FEHD remove the wasp nest at my home?
It depends on the location. FEHD provides a removal service for nests in public places, but residential premises with a management company and all private non-residential premises fall outside that service — removal has to be arranged by the management company or the owner.
The nest is small — can I just spray it myself?
We don't recommend it. Even a small nest can react fast once disturbed, and nests are usually up high, so the risk is out of proportion to the size. Smaller nests are actually cheaper and quicker to have removed professionally — that's the best time to act, not the time to try it yourself.
When's the best time to get a wasp nest removed?
The moment you find it. Nests keep growing through summer and are generally largest and most aggressive around August to October — the longer you wait, the higher both the risk and the cost. The removal itself is usually scheduled for after dusk, once the colony has returned to the nest.
How much does wasp nest removal cost?
There's no fixed price — it mainly depends on height and accessibility, nest size, and location. Send us a photo over WhatsApp and we can usually give you a ballpark the same day; an on-site inspection is HK$350, fully credited when you book.
