Spider Control
Most household spiders are harmless and even helpful, but heavy webbing or venomous species like black widows and brown recluses are worth professional treatment. Control focuses on reducing the insects spiders feed on and sealing entry points.
Typical cost: $120 to $350

How much does spider control cost?
PestPin's national planning range for spider control is $120 to $350, with a $200 planning midpoint. Venomous species, heavy webbing, difficult access, and recurring service can increase the quote. This is an editorial budget range, not a local price.
What does a spider look like?
- Most spiders indoors are harmless, but you cannot tell a dangerous one from a safe one at a glance, so never get close to check.
- The two worth worrying about in the US are the black widow and the brown recluse, and both hide in quiet spots like garages, basements, closets, and woodpiles.
- If a spider looks unusual or you are worried, do not handle it. Photograph it from a safe distance and use our free identifier, or call a pro.
Signs of a spider problem
- Webs in corners, eaves, basements, and garages
- Egg sacs in sheltered areas
- Frequent sightings of the same species
- Bites or sightings of venomous species
Treatment options
- Web removal and targeted treatment of harborage
- Perimeter treatment to reduce prey insects
- Crack-and-crevice treatment at entry points
- Identification and focused control of venomous species
How to prevent them
- Reduce other insects (spiders' food source)
- Seal cracks and install door sweeps
- Clear clutter, woodpiles, and debris near the home
- Keep outdoor lighting away from doors (it attracts prey insects)
When they're most active
Spiders are often most noticeable in late summer and fall as they mature and search for mates.
Common spider control types
Wolf spiders: the big fast one that runs across the floor
The spider most people call about is the big, fast brown one that bolts across a basement floor or sits flat on the wall at night, and never builds a web indoors. That is usually a wolf spider, and it came in hunting, following crickets and other insects through a gap under a door, a torn screen, or an unsealed garage. Because it roams instead of sitting in one spot, sealing those gaps and cutting down the insects it feeds on does more than spraying baseboards. If one looks like it is covered in fuzz that moves, that is a female carrying her young on her back, and it is not a sign the house is infested.
Spider Control: frequently asked questions
Are most house spiders dangerous?
No, the vast majority are harmless. The main concerns are black widows and brown recluses, which a pro can identify and treat.
How do I keep spiders out?
Reduce the insects they eat, seal entry points, and clear webbing and clutter where they shelter.
Are wolf spiders dangerous to have in the house?
Wolf spiders are not aggressive and they do not build webs indoors, so most encounters are a startled spider trying to get away from you. They can bite if trapped against skin. If you are worried about a bite or any reaction to one, talk to a doctor rather than waiting it out.
