Now, a hilarious twist: 90% of reported spider bites in the UK are actually caused by something else. You woke up with a red lump? It was a mosquito. A mysterious mark on your leg? That’s bed bug or, more embarrassingly, a skin infection from that weird mole you scratched. Doctors love laughing about this—patients insist a spider “got them,” but the spider is just sitting in the corner, absolutely innocent.
There’s even a term for it: “medically unexplained spider bite.” It’s the medical version of “the dog ate my homework.” We blame the spider because it’s the easiest scapegoat. Also, spiders don’t carry diseases like mosquitoes, so even if they did bite you, you’d just be a bit grumpy.
What Would Happen If One Actually Bit You?
Let’s imagine the worst-case scenario. A large Cross Spider (the one with the white cross on its back) decides to chomp your finger. You’d feel a tiny pinch, like a pinprick. You might get a small, red bump that itches for a few hours. Then you’d tell your friends, “A spider bit me and I lived,” and they’d roll their eyes. That’s it. No hospital. No turning into a web-slinger.
The real danger? Infection from scratching a bite—just like you would with a mosquito bite. So don’t scratch. Also, don’t panic. The UK has about 670 species of spiders, and exactly zero of them can kill you. In Australia, they have funnel-web spiders that make you say goodbye to your family. Here, we have the Money Spider, which is so small it bites your soul, not your skin.
