The UK is home to hundreds to breeds of spiders. This being said, there are three common spiders in the UK that are capable of biting you: the cellar spider, the woodlouse spider and the false widow spider. Their bites are painful and have been known to cause swelling for a few hours. The UK's most common spider is the Black lace-weavers, which are usually found inside homes all year round. Spiders are generally not something to be concerned about, but they can be very distressing for someone with a phobia. To have a spider problem addressed, a professional can be called to rid them from your home or business.
