The woodlice spider, Dysdera crocata, is one of the few british spiders who has fangs that can penetrate our skin. Luckily, it usually uses them to pierce the armour of its favourite prey, woodlice (hence the name) instead. Apparently humans can have an allergic reaction to the bite. It is often found in gardens in damp places were woodlice are found, like under stones and logs. They are nocturnal. We found this cheeky little creep in the kitchen a couple of days ago. No sign of more, thank goodness!
