Wolf Spider Control in Kansas City

Wolf spiders are the big, fast, hairy brown spiders that run across basement floors in fall. They look alarming but are harmless hunters that don't build webs — they wander in from the yard.

Why they come inside

They hunt on the ground and follow insects and warmth indoors as nights cool, usually through gaps under doors, garage doors and basement windows. Most wolf spiders indoors are wanderers, not an infestation.

How we handle wolf spiders

A perimeter treatment along the foundation, door thresholds and garage edges, plus sealing recommendations for where they are getting in. Because they hunt other insects, reducing crickets and other ground insects around the house matters as much as anything.

What you can do

Install door sweeps and fix the weatherstripping on garage and basement doors. Keep mulch, leaf litter and stored items away from the foundation, and switch exterior lights to yellow bulbs to draw fewer insects.

Wolf Spider Control in Kansas City — Common Questions

Are wolf spiders dangerous?+

No. They can bite if handled, but the bite is mild. They are not considered medically significant.

Do wolf spiders mean I have an infestation?+

Rarely. They wander in from outside. Seeing several means there are gaps at ground level and insects for them to hunt nearby.

Why are there so many in fall?+

Males wander looking for mates in late summer and fall, and cooling nights push them toward buildings.
