Southern Utah's desert climate is ideal spider habitat. Knowing which species are dangerous helps you protect your family.
Glossy black with a red hourglass marking. Found in garages, sheds, and under outdoor furniture. Venomous — bites require medical attention. The most medically significant spider in Utah.
Brown recluses do not occur in Utah (USU Extension). Nearly every reported recluse here is a harmless funnel weaver or cellar spider. We identify photos free — because knowing what you actually have matters.
Large, fast-moving ground hunters that enter homes seeking prey. Non-venomous to humans but alarming due to size. Very common in St. George homes and garages.
Utah's only recluse relative, native to Washington County's desert. It lives outdoors in native vegetation and rodent burrows and is rarely encountered indoors — respect it, but it is not the explanation for typical indoor sightings.
We physically remove all webs and egg sacs from eaves, corners, garages, and crawl spaces. Destroying egg sacs prevents the next generation from hatching — each sac can contain 100–400 spiderlings.
Residual insecticide applied to harborage zones — dark corners, behind furniture, inside storage areas, and along baseboards where spiders travel and hide.
Exterior perimeter barrier treatment eliminates the insects spiders feed on. No food source means spiders leave. This is the key to long-term spider reduction, not just killing individual spiders.
Yes. Black widows are very common in Southern Utah, especially in garages, sheds, woodpiles, and under patio furniture. They prefer dark, undisturbed areas. Wernex technicians are trained to locate and eliminate black widow populations safely.
According to Utah State University Extension, brown recluse spiders do not occur in Utah. The state's only recluse relative is the desert recluse, found in Washington County, which lives outdoors and is rarely encountered indoors. Most suspected 'brown recluses' in St. George homes turn out to be harmless funnel weavers or cellar spiders — send us a photo and we'll identify it for free.
We use a three-part approach: web removal and egg sac destruction, targeted residual sprays in harborage areas, and exterior perimeter barrier treatment. We also treat for the insects spiders feed on — eliminating their food source reduces spider populations long-term.
We recommend quarterly treatments to maintain continuous protection, especially during the warmer months when spider activity peaks. Our protection plans include re-service at no cost if spiders return between treatments.
