Cockroaches and rodents in tong lau
Wooden structures, ageing drainage, and connected back lanes: sealing entry routes is step one, treating inside the flat is only the second half of the job.

Pest Control in Sham Shui Po: Some of Hong Kong's Oldest Tong Lau, Handled Street by Street
If Sham Shui Po's pest problems come down to one thing, it's building age. This is home to some of Hong Kong's oldest tong lau blocks — wooden staircases, shared drainage, connected back lanes, and subdivided units are all common — and the cockroach and rodent networks running through them have been decades in the making. Add the wholesale and retail goods flow around Apliu Street and Yu Chau Street, and one hard number: FEHD's mosquito-trap index recorded a monthly combined 32.1% at Cheung Sha Wan in July 2026 — Level III, the highest of all 62 monitoring areas that month, and up from June's 29.2%. Yet the neighbouring Sham Shui Po and Shek Kip Mei stations, the same month, only reached 4.9% — more than a sixfold difference across one street. Pest control here can't run on one approach for the whole district.
Local pest reality
Subdivided flats
One unit affected can mean the whole floor is affected; we treat entry points unit by unit and can advise on coordinating with neighbouring units (without coordination, it comes back fast).
Bed bugs
Older buildings with high tenant turnover are a higher-risk combination; if you suspect an infestation, run the five-minute self-check early.
Cheung Sha Wan mosquitoes
The index reading is high, and it's low-rise and rooftop residents who feel it most; standing water in back-lane drains and rooftop clutter is the main front.
Sham Shui Po pest risk brief (as of 2026-07)
According to FEHD's Area Gravidtrap Index (compiled by Averta Pest Control, as of 2026-07), Cheung Sha Wan recorded the highest July reading in Sham Shui Po at 32.1% — ranked 1 of all 62 monitoring areas territory-wide.
FEHD Rodent Reference Index 2023: Sham Shui Po annual 1.2% (H1 1.8%, H2 0.6%), ranked 17 of 19 survey divisions. Hong Kong has only ~50 monitoring points in total and some divisions have exactly one — a limitation worth citing alongside any ranking.

Frequently asked questions
The whole tong lau is the same — does treating just my flat even help?
Yes — but aim for the right target. What you can control is whether pests can get into your unit. Sealing drains, pipe gaps, door gaps, plus a residual barrier, stops entry. Whole-building treatment needs the owners' corporation or the block owner to act — we also run whole-tong-lau programs and can help you estimate the scope.
I live in a subdivided flat and my neighbour won't cooperate — what then?
Very common. The approach is to make your unit as tight as possible on its own: seal every entry point, clear hiding spots, and turn your unit into the hardest one on the floor to get into. At inspection we'll spell out in writing what's within your control and what needs coordination.
Why are Cheung Sha Wan's mosquitoes so bad?
There's a number behind it: FEHD's monthly combined index recorded 32.1% at Cheung Sha Wan in July 2026, Level III — the highest of all 62 monitoring areas that month, and up from June's 29.2%. But the neighbouring Sham Shui Po and Shek Kip Mei stations recorded only 4.9% the same month — more than a sixfold difference across one street. The difference comes down to standing water: back-lane drains and rooftop clutter are the main front, and in-unit prevention only treats the symptom.
Do you handle wholesale and retail shops?
Yes. For high-goods-flow shops, the focus is on stock movement and storage areas — cardboard is a five-star hotel for cockroaches and rodents; work is done outside trading hours, with a service record provided.
