Yellow sac spiders are a smaller species of spider. Adult bodies grow to be between 1/4 and 5/16 of an inch in length. These spiders are pale beige to yellow and often have a green tinge. The tips of their long, thin legs are dark brown, and their dark brown eyes are arranged in two rows of four.

Where are yellow sac spiders found?

Yellow sac spiders can be found outside creating their characteristic web masses in trees, bushes, woodpiles, and leaf piles. They are nocturnal and hide in their web during the daytime, emerging at night to hunt for food. Yellow sac spiders accidentally enter Iowa & Illinois homes while foraging for food and can be found in basements, closets, attics, in draperies, near faucets, and around appliances. They will also enter homes and other buildings when the weather cools in the fall.

What do yellow sac spiders eat?

Yellow sac spiders are predators and feed on a variety of insects and other spiders. Yellow sac spiders may bite a person if they are directly handled; their venom is usually not strong enough to cause a major reaction. A bite from a yellow sac spider usually results in local pain, short-term soreness, and a raised red welt.

DIY yellow sac spider prevention and control tips

Sealing cracks in the foundation and exterior walls, installing door sweeps on exterior doors, and removing piles of leaves and other organic debris will help discourage spider activity in your home and on your property. We also recommend storing woodpiles well away from your building and eliminating clutter in storage areas, closets, and attics. Finally, since yellow sac spiders feed on insects, you should make sure your property is free of potential food sources. This can be accomplished by implementing a year-round pest control program.
