UK Spiders On The Rise: Hospital Bites Surge

A mild winter and warm spring have led to a significant population boom for the noble false widow spider in the UK, resulting in a notable rise in related hospital admissions. NHS figures indicate that spider bite admissions climbed from 47 in 2015 to 100 in 2025, a trend zoologists attribute to the expanding numbers of this venomous arachnid.

The noble false widow, often mistaken for the deadly black widow, is characterized by its globular body and distinctive cream markings. Originally from the Canary Islands and Madeira, it has successfully established itself across Britain. Its bite, while typically comparable to a wasp sting, can lead to infections and prolonged illness in some rare cases.

As temperatures rise, the noble false widow reproduces, making it crucial to take preventive measures. These spiders are commonly found in sheds, outbuildings, and homes. Their webs are loose and tangled, often with a hidden tube where the spider resides. The British Pest Control Association recommends regular vacuuming of webs and sealing potential entry points to deter them from nesting in homes.
