If you spot a large wheel-shaped web in the garden, chances are it was put there by an orb weaver. This particular green orb weaver is typically found outdoors, but can enter the home. While the venom of these spiders is related to that of a black widow, they are not dangerous to humans and the effects are minimal. While bites are rare, if bitten you’ll most likely experience a small area of redness and swelling with minor pain. Orb weavers are beneficial garden predators.
