The UK is a safe haven for the spider-fearful. We don’t have tarantulas roaming the moors or funnel-webs hiding in our wellies. Our spiders are the mild-mannered, slightly grumpy grannies of the arachnid world. They might give you a sharp word, but they won’t harm you.
So, the answer is no, there are no truly poisonous spiders in the UK that should keep you up at night. The only poison in the room is your imagination after you’ve watched one too many nature documentaries. Go on, let that little guy live. He’s probably just looking for a leftover crisp.
