Residents in the UK are being urged to keep their windows shut this August as the poisonous False Widow spider reaches its peak mating season. Known as Britain’s most hazardous native spider, it becomes particularly active in late summer.
Male False Widows leave their webs in search of mates and can enter homes through open windows, vents, or drains. Dr. Tom Elwood, a renowned spider expert, explains that while bites are not fatal, they can be extremely uncomfortable, often compared to the sting of a wasp.
In some instances, the venom can cause severe swelling, burning pain, and fever. Medical reports across the UK have documented these more serious reactions, highlighting the need for caution.
False Widows are increasingly common in British homes, especially in warm, secluded areas such as attics, sheds, and window frames. Their sticky webs are usually found in corners and crevices.
To reduce the risk of encounters, experts recommend keeping windows closed during this peak activity period. Additional precautions include cleaning window frames weekly to remove webs and sealing cracks around doors, vents, and pipes where spiders might enter.
While the False Widow is unlikely to be fatal, staying aware and taking preventive measures can help residents avoid painful bites during the spider’s busiest season.
