Pest Control in Tsz Wan Shan

For standard sprays and gels, you typically only need to stay out of treated rooms for 2-4 hours until surfaces dry. Fogging or flea treatments may require 4-6 hours away. Whole-structure fumigation (rare, mostly for termites or severe bed bugs) means vacating for 1-3 days. Your technician must give you re-entry instructions — ask if they don't.

Bait and traps knock down the current population, but permanence comes from exclusion: sealing gaps bigger than a pencil around pipes, vents, doors and rooflines, plus removing food sources. Good rodent jobs are quoted as a program — initial treatment, follow-up checks, and proofing — not a single bait drop.

A typical visit includes an inspection, interior treatment of kitchens/bathrooms/entry points, an exterior perimeter barrier spray, and a written report. It usually covers common crawling insects (ants, roaches, spiders). Rodents, termites, bed bugs, wasps and mosquitoes are almost always quoted separately — confirm what's on the ticket.

It depends on the pest. Wasp nests and one-off ant trails are usually solved in a single visit. Cockroaches, bed bugs, fleas and rodents almost always need 2-3 visits, because eggs laid before the first treatment hatch after it. Ask upfront whether follow-up visits are included in the quoted price.

Warm humid evenings from roughly April to June trigger termite swarms; winged termites entering near lights can indicate a colony in or near the building. Turn off lights, close windows, and if you find shed wings indoors repeatedly, book an inspection — treatment for an established colony costs HK$3,000-HK$12,000.

The building management or incorporated owners are responsible for common areas (refuse rooms, pipe ducts, lobbies); the FEHD handles public streets and markets. You only pay privately for treatment inside your own flat, so report common-area sightings to management first.
