How to Get Rid of Spiders (and Which Ones to Worry About)
Most house spiders are harmless and even helpful, eating other insects. The goal usually isn't zero spiders, it's controlling webbing and watching for the few venomous species.
Reduce spiders the easy way
- Cut down the insects they eat, fewer bugs means fewer spiders.
- Seal cracks and add door sweeps to block entry.
- Clear webs, clutter, and woodpiles near the house.
- Move outdoor lights away from doors; light attracts the insects spiders hunt.
The two to take seriously
Black widows (shiny black with a red hourglass) and brown recluses (a violin-shaped mark) can deliver medically significant bites. If you see either repeatedly, get a professional identification and treatment.
Heavy webbing that keeps returning, or any venomous-species sighting, is worth a professional treatment that targets harborage and the insects spiders feed on.
