Introduction: Why the Daddy Longlegs Venom Myth Persists

The daddy longlegs venom myth claims that these delicate, long-legged creatures are the most venomous spiders in the world but can’t bite humans because their fangs are too small. It’s a story repeated for generations, but science shows it’s false.

Part of the confusion comes from the name itself—“daddy longlegs” is used for three very different creatures: harvestmen, cellar spiders, and crane flies. In this article, we’ll bust the myth, highlight the truth about each species, and explain why these creatures are harmless (and even helpful).
