Experts have warned that poison-resistant 'super rats' could invade homes across the UK as temperatures drop this winter. The British Pest Control Association (BPCA) reports that these rodents are becoming immune to traditional poisons sold in supermarkets, which may actually be fueling their growth.
Simon Forrester, chief executive of the BPCA, explained that while normal rats are killed by these poisons, resistant species are feeding on the toxic pellets, increasing their size and strength. He noted that stronger rodenticides are available but are subject to strict legislation and should only be used by professional pest controllers.
The BPCA has observed an increase in reports of poison-resistant rats in recent years, predicting a further surge as rodents seek warmth and food indoors during colder months. Rats can squeeze through gaps as small as three-quarters of an inch and often hide under floorboards, in walls, or in lofts.
Homeowners are urged to rat-proof their properties by fitting strips to door bottoms, sealing gaps in exterior walls, repairing roof damage, and covering drains to prevent entry via pipes. The BPCA emphasizes that professional pest control may be necessary to tackle resistant populations effectively.
