Where is the Habitat of Brown House Spiders in Texas?

Brown house spiders in Texas are pretty adaptable, but they’re most at home indoors. They love dark, undisturbed places where they can spin their messy, tangled webs.

Their webs are pretty easy to spot because they’re so disorganized and messy compared to the more structured webs of other spiders.

Outside, you can find brown house spiders in sheltered areas like under rocks, in woodpiles, or any other spot that offers some protection from the elements and predators.
