The Cost of
Waiting One Week.
Every figure below is sourced from FEHD enforcement records, Buildings Department claims data, and HKPC surveillance reports. The numbers don't argue. They document.
German Cockroach (Blattella germanica)
A single breeding pair produces 280 offspring in one quarter. In a 40-floor estate, infestation spreads to adjacent units within 6 weeks via pipe chases and cable conduits.
Formosan Subterranean Termite (Coptotermes formosanus)
Hong Kong's most destructive urban pest. A mature colony of 3M workers consumes 13g of wood daily — undetected in concrete-encased timber for 18–24 months before visible damage.
Norway Rat (Rattus norvegicus)
In the 2024 FEHD annual inspection cycle, 47% of restaurant prosecutions cited rodent evidence. Average closure duration: 4.2 days. Average revenue loss: HK$68,000.
All Species — Pre-1980 Structures
Buildings constructed before 1980 show 3.4× higher infestation rates due to degraded pipe seals, unlined drainage channels, and timber sub-flooring. Kowloon City and Sham Shui Po districts lead in reports.
Rodent Cable Damage
Three documented incidents in Hong Kong data centres in 2024. Rodents target cable insulation for nesting material. Standard pest control gaps in raised floor plenum spaces are the primary entry vector.
Cost of Inaction — Commercial Kitchen
FEHD inspection cycles operate on 6-week intervals in Category A premises. First-sighting to prosecution averages 6.2 weeks. Post-prosecution, re-inspection is mandatory within 14 days — at operator expense.
