What Are House Spiders?
The spiders most people find indoors are common, harmless house spiders that spin cobwebs in corners, basements, garages, and other quiet spots. They are not aggressive and generally bite only if trapped against skin.
They follow food, so a lot of spiders usually means a lot of insect prey is available in or around the home.
How to Reduce House Spiders
Because spiders track prey, the most effective control reduces the insects they eat, clears webs, and seals entry points, rather than relying on spraying spiders directly.
- Remove webs and egg sacs with regular dusting and vacuuming.
- Reduce outdoor lighting that attracts the insects spiders feed on.
- Seal cracks, gaps, and door sweeps and add weatherstripping.
- Declutter storage areas and treat harborage zones where needed.

Common Questions
Are house spiders dangerous?
The vast majority are harmless and even helpful, eating other insects. Only a few Texas spiders, like the black widow and brown recluse, are medically important.
Why do I suddenly have a lot of spiders?
Usually because there is plenty of insect prey, or seasonal changes push them indoors. Reducing prey and sealing entry points lowers their numbers.
How do I keep spiders out?
Clear webs, reduce attractant lighting and insect prey, seal gaps and door sweeps, and declutter the quiet areas where they hide.
