Service Overview
Utah’s dry climate and mix of foothill, desert, and suburban landscapes create ideal conditions for spiders, and it’s not unusual for a single acre of land to support hundreds of thousands of them. Most of these spiders never come near a house and actually help by preying on flies, mosquitoes, and other insects. The handful of species that do move indoors are usually chasing one of two things, shelter from temperature swings or a food source created by other bugs already inside. That’s why spider activity tends to spike twice a year in this valley, once in late summer as spiders mature and search for mates, and again in fall as cooling temperatures push them toward basements, garages, and crawl spaces.
Spiders Commonly Found in Salt Lake City Homes
1. Black widow spiders
Recognizable by a shiny black body and a red hourglass marking, black widows build messy, irregular webs in undisturbed spots like woodpiles, sheds, garages, and water meter boxes. Their bite is neurotoxic and should always be evaluated by a doctor, particularly for children or older adults.
2. Hobo spiders
The most commonly reported spider in Utah homes, hobo spiders build funnel shaped webs at ground level and are often found in basements, window wells, and along foundation walls. They're strong runners but poor climbers, so they rarely turn up on ceilings or upper floors.
3. Wolf spiders
Large, fast moving, and covered in hair, wolf spiders don't build webs at all. They hunt on foot, which is usually what makes them so startling to homeowners, but their bite is painful rather than dangerous.
4. Yellow sac spiders
Pale in color and often found near the ceiling where it meets the wall, this species is responsible for more bites than any other spider in the area, though reactions are typically mild.

How Our Spider Control Process Works
1. Inspection and identification
We walk the property to confirm which species are present, since black widow and hobo spider treatments differ from what's needed for wolf spiders or yellow sac spiders.
2. Web and egg sac removal
Existing webs, egg sacs, and visible nesting areas are cleared as part of the service, not treated as a separate charge.
3. Targeted interior treatment
Basements, garages, crawl spaces, window wells, and closets get focused treatment in the specific spots where each species tends to hide.
4. Exterior barrier treatment
We treat the foundation, eaves, woodpiles, and other outdoor hiding spots using long lasting, family safe products designed to keep new spiders from settling in.
5. Exclusion recommendations
Since spiders often follow other insects indoors, we point out gaps, torn screens, and entry points that are worth sealing to cut off the food source drawing them in.
Prevention Tips Between Treatments
- Clear clutter, woodpiles, and stored boxes away from exterior walls and garage corners.
- Repair or replace torn window screens and door sweeps.
- Reduce outdoor lighting near entry points, since bright lights attract the insects spiders feed on.
- Remove webs and egg sacs as soon as you spot them rather than letting them establish.
- Store firewood at least a few feet off the ground and away from the house.
Black widow spiders are the only medically significant spider commonly found in the Salt Lake Valley, with a neurotoxic bite that should be checked by a doctor. Hobo spiders were once believed to cause dangerous bites, but current research shows their venom is not medically significant to humans.
Basements offer the dark, undisturbed, temperature stable conditions that hobo spiders and cellar spiders prefer, especially if there's clutter or moisture nearby. Spider control that targets basements, window wells, and crawl spaces directly is usually the most effective fix.
Yes. Since spiders follow food sources, a treatment that reduces flies, ants, and other small insects around your home often lowers spider activity as a side effect, and vice versa.
Yes. Professional treatments use family and pet safe products applied by trained technicians, with drying times observed before treated areas are used again.
Most Salt Lake City homes do well on a quarterly schedule, with extra attention in late summer and fall when spider activity typically increases.
Cleaning, decluttering, and sealing entry points help reduce spider activity, but they rarely resolve an established infestation, especially with species like black widows that nest in hard to reach areas. Professional treatment targets the nesting sites directly for longer lasting results.
