Residents across the United Kingdom are being urged to keep their windows shut both day and night as the False Widow spider—a venomous species related to the Black Widow—enters its peak mating season.
This alert comes from Dr. Tom Elwood, a top arachnologist, who warns that now is not the time for panic—but for smart preparation. “August is when male spiders become active,” Elwood explained. “They’re searching for a mate and will wander through open windows, vents, or even bathroom drains.”
Why This Spider Is a Serious Concern
The False Widow, though not lethal, can deliver a bite with wasp-like pain, causing burning, swelling, and fever. It’s one of the few spider species in the UK known to regularly bite humans, and experts say their presence in homes is increasing.
The spider’s venom has led to multiple medical reports in recent years. BBC News previously documented cases where victims experienced intense skin irritation and systemic reactions—making it a pest not to ignore.
How to Protect Your Home
- Keep all windows shut—day and night, especially during the next four weeks.
- Clean windows and frames weekly—spiders prefer dusty, grimy surfaces where webs adhere better.
- Seal any gaps or cracks—particularly around doors, vents, and pipe openings.
- Use peppermint oil—a natural deterrent known to repel spiders.
- Remove spider webs regularly to disrupt their breeding zones.
- Trim foliage attached to your house to eliminate easy access pathways.
“Spiders are already on the move,” warns Dr. Elwood. “You may not see them, but they’re climbing walls, slipping in through vents, and squeezing through cracks.”
As experts emphasize, preparation now can save you from a very unpleasant surprise later. With climate change contributing to longer mating seasons and increased indoor spider sightings, now is the time to act.
