True: False widow spiders are one of 15 spider species living in the UK which can bite humans.

Pest Control Information Sheet of False Widow Spiders website supports the claim. False widow spiders are native to the United Kingdom. They are most active at night and during the day they tend to remain near their webs. These species of spiders are not aggressive towards humans and are most likely to bite when accidentally provoked or trapped in clothing. According to the Natural History Museum website, there are over 650 species of spider known to live in the UK and only 15 of these recorded species have been known to bite humans. For most people, a bite from the false widow will be similar to a bee or wasp sting.
