Every summer, tabloid newspapers run headlines like “KILLER SPIDERS INVADE KENT!” with a photo of a spider the size of a dinner plate. Spoiler: it’s always a picture taken with a macro lens. In reality, our largest native spider, the Cardinal Spider, looks scary but is a total softie. It eats other spiders and runs away from humans faster than a politician dodging a question.
These are the 14 spiders in the UK that can bite you - and which ones
Fun fact: there’s a spider called the Ladybird Spider that’s covered in red and black spots. It’s so rare and cute, entomologists cry when they find one. It could bite you, but it’d probably apologize afterward.
What Actually Bites Brits?
Statistically, you’re more likely to be bitten by a horsefly, a midge, or your own insecurities during a job interview. The NHS reports fewer than a dozen serious spider bites per year in the entire country. Compare that to the number of people who get injured falling out of bed—like 1,000 per day. So maybe worry less about spiders and more about your mattress discipline.
Even the False Widow panic is overblown. A study in 2026 found that most “bites” blamed on spiders were actually skin infections from bacteria. So if you wake up with a red mark, it’s probably not a spider—it’s your poor hygiene. (Kidding. Mostly.)
