Spiders are a fact of life in Utah, but they don’t need to share your living room. Late summer and early fall bring a wave of wolf spiders, hobo spiders, and other house spiders looking for shelter, and black widows like the undisturbed corners of window wells, garages, and woodpiles.
Because spiders follow their food, we treat the insects that attract them as well as the spiders themselves — and knock down webs and egg sacs we can reach so they don’t hatch next season.
Signs you may need spiders help
- Webs in window wells, eaves, and under decks
- Spiders in basements, garages, and storage rooms
- Round, papery egg sacs in corners
- Black widows in undisturbed areas outdoors
How we handle spiders
- Inspect harborage areas inside and out
- De-web eaves, windows, and entryways
- Treat cracks, crevices, and window wells
- Reduce the insects spiders feed on
- Recommend sealing and clutter fixes
When to expect them in Utah County
Expect the most spider sightings in Utah County from late August into October, when males roam looking for mates and shelter.
Prevention tips from our team
- Install window well covers
- Store boxes in sealed plastic bins instead of cardboard
- Use yellow “bug” bulbs or motion lights near doors
- Keep firewood away from the house and wear gloves when handling it
Family & pet safety: Treatments are placed in cracks, crevices, and outdoor harborage areas rather than broadcast over living spaces.
