A great, robust little spider commonplace in the UK is the woodlouse spider. It is one of the few true UK biters. Relatively harmless, but has fangs that CAN penetrate human skin and deliver a painful bite - akin to a wasp sting. Often a nasty threat to gardeners, the Woodlouse spider is perhaps, alongside the false widow (steotoda nobilis) one of Britain's most venomous spiders!
