What are False Widow Spiders?
With a body length of 10-15mm (female) and 3-6mm (male), the False Black Widow Spider is shiny black but does not have the red double triangle marking of its more dangerous cousin. It’s believed that Steatoda nobilis was introduced to the UK in the 1880s from the Canary Islands. Spreading north and east since then, it has been spotted as far apart as North Norfolk and South Wales. Two species of False Widow Spider (Steatoda grossa and Steatoda bipunctata) are now widespread across the UK.
How do you know if you have False Widow Spiders on your property?
Commonly found in sheds, porches and homes, it can be difficult to categorically identify a False Widow Spider. It will spin a loose tangle of non-sticky webbing with the addition of a tube of silk leading into a space where it can hide during daylight hours. Usual locations for these webs include window and door frames, eaves, pipes, gutters and outbuildings. Increasing in numbers during the warmer months, by late summer and autumn False Widow Spiders will become more noticeable as the males wander to look for a mate.
There are a few issues to consider if you discover False Widow Spiders on your property or in a public area:
- It is one of the very few spiders in the UK which can bite
- It is the only species of spider whose venom can affect humans
- It is not aggressive and will not attack people unless it is under threat
- It has a bite which can cause a reaction similar to a wasp sting, although the effects can be longer-lasting and extend beyond the site of the initial puncture wound
- It is mostly likely to be seen in Autumn, particularly during October
- A non-native species, it is now more widespread across the UK (probably due to climate change)
