Urgent Warning: Keep Windows Shut to Stop the Spider from Entering Homes
UK residents are being advised to keep windows closed around the clock as the venomous False Widow spider enters its most active mating period this August.
Dr. Tom Elwood, a leading spider expert, warns that male spiders are now actively seeking mates and may enter homes through open windows, vents, or drains. While not deadly, their bite can cause significant pain similar to a wasp sting.
The False Widow – Britain’s most dangerous native spider – is increasingly found in homes. Its venom can trigger severe swelling, burning sensations, and even fever in some cases, with multiple medical reports confirming these reactions.
To protect homes, experts recommend: keeping windows shut day and night for the next month, weekly cleaning of window frames (where webs easily stick), and sealing cracks around doors and pipes.
Additional precautions include using peppermint oil as a natural repellent, regularly removing spider webs, and trimming plants touching house walls to eliminate access routes.
“Spiders are already on the move,” Dr. Elwood cautions. “They’re climbing walls and finding entry points you might not notice.” With climate change extending mating seasons, sightings are becoming more common.
While there’s no need for panic, simple preventive measures now can avoid painful encounters later. Experts stress that being proactive is key to keeping these unwelcome guests outside where they belong.
