Appearance
An adult yellow sac spider’s body is about a quarter-inch long. They are yellow or beige in color with dark
brown jaws. Like most spiders, they have two body segments and eight legs. Yellow sac spiders spin small, concentrated webs that look like silk tubes. These sacs may hold eggs, harbor spiderlings, or serve as a daytime hiding spot.
How Do Yellow Sac Spiders Get Inside Buildings?
Although you may find them underneath piles of brush or behind tree bark, yellow sac spiders often enter homes when the weather starts to cool. Since they can’t survive the cold, they need a warm place to spend the winter. Gaps around doors, broken vents, and torn screens make it easy for yellow sac spiders to get inside. Household pests like ants and flies provide them with plenty of food.
Yellow sac spiders are common inside both residential and commercial spaces. Pests that get access any small crack to get indoors are difficult to control. Yellow sac spiders can also blend in easily against light-colored walls, and their small webs often go unnoticed. Some species have adapted to human structures so well that they prefer to deposit their eggs indoors.
