The most famous of our eight-legged cast is the false widow spider (Steatoda nobilis). It’s the one that makes tabloid headlines, often exaggerated into a “killer” narrative. In reality, its bite feels like a wasp sting—unpleasant, yes, but rarely requiring medical attention.
Then there’s the tube web spider (Segestria florentina), which has iridescent green fangs that look alarmingly sci-fi. It lives in walls and fences, and while its venom can cause local swelling, it’s still more bark than bite. For context, you are statistically more likely to be struck by lightning in the UK than to have a serious reaction to any native spider.
The Lighter Side of Scary
What about the woodlouse spider (Dysdera crocata)? It’s a tiny predator with oversized jaws, built specifically to crunch woodlice. Its venom is potent enough to paralyse its prey, but it’s no match for your hard-won immunity to Sunday night dread. A bite might leave a red mark, but nothing a cup of tea can’t soothe.
Fun fact: the UK’s largest spider—the raft spider—can walk on water. It’s also completely harmless to humans. Imagine the dinner party chat: “I was chased by a spider that does the Jesus trick.” Instant legend status.
