As the summer sun warms the UK, it’s not just barbecues and garden parties that are ramping up—so is the activity of one of Britain’s most notorious eight-legged residents: the False Widow spider.
August marks peak mating season for these venomous arachnids, and residents are being urged to keep windows shut to prevent them from entering homes. Often described as Britain’s most hazardous native spider, the False Widow becomes particularly active during late summer, and experts are sounding the alarm.
What’s the Risk?
Male False Widows leave their webs in search of mates, and in doing so, they may sneak into homes through open windows, vents, or even drains. While their bite isn’t fatal, it’s far from pleasant.
Dr. Tom Elwood, a leading UK spider expert, compares the bite to a wasp sting—painful and irritating, with some people experiencing burning sensations, swelling, and even fever. A number of medical reports across the UK have highlighted these more severe reactions, raising concern about the growing number of sightings.
Where Are They Hiding?
False Widow spiders tend to favor warm, hidden corners—think attics, garden sheds, and around window frames. Their sticky, irregular webs are often spotted tucked into crevices and quiet spots around the house.
How to Keep Them Out
To avoid any unwanted visitors, experts recommend a few simple steps:
- Keep windows closed—especially at night or during warmer parts of the day.
- Clean window frames weekly to remove webs and discourage nesting.
- Seal any cracks around doors, vents, and pipes where spiders might sneak in.
While the False Widow spider doesn’t pose a life-threatening danger, a little awareness and prevention can go a long way in avoiding painful encounters during their most active season.
