Do daddy long legs contain venom do they contain deadly venom?
Daddy long leg spiders, of the Family Pholcidae, do NOT contain deadly venom. They do contain venom. All spiders do. But when the myth started that they have the deadliest venom, there had been absolutely no research done on the toxicology of the venom. Giving the myth no basis. Now that some research has been done, they have concluded that the venom is relatively weak.
