Conservation status

The false widow spider is afforded no conservation status.


Due to its notoriety as the UK’s most venomous spider, Steatoda nobilis may be threatened by remedial pest control.


Steatoda nobilis is currently a colonising species in the UK and has been expanding rapidly since the late 1980’s. This is likely to be in response to increasing temperatures in the UK caused by climate change.

Risk Statement

Although this is a colonising species in the UK, it does occupy a somewhat vacant niche and is unlikely to have an impact on other species of spider.
