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.

They are often found in basements, attics, closets, and behind furniture—basically, anywhere they can stay hidden and catch their next meal.

These spiders like to keep a low profile, so their webs are usually tucked away in corners, under furniture, or in other out-of-the-way spots.

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.

They’re pretty good at finding places that give them cover and plenty of hunting opportunities. Whether they’re inside your house or outside in the garden, these spiders are quite common in Texas.

The bites from brown house spiders are generally mild and result in minor symptoms such as pain, redness, and swelling. Serious reactions are uncommon and typically only occur in individuals with specific sensitivities.

Despite their fearsome appearance, these spiders pose minimal risk to humans and are not considered dangerous.
