Daddy Long Legs / Harvestmen (Opiliones)
Daddy long legs, properly known as harvestmen, are not true spiders but a related arachnid order lacking venom glands and silk-producing organs. They are completely harmless to humans and are actually beneficial, feeding on decaying organic matter, small insects, and fungi. The popular belief that they are highly venomous is a myth — they have no venom whatsoever. Their presence is usually a sign of moisture or organic debris and is best addressed by improving ventilation and reducing humidity rather than chemical treatment.
