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.
Light brown with a violin-shaped marking. Hides in storage boxes, closets, and undisturbed areas. Bites can cause necrotic tissue damage. Less common but present in Southern Utah.
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.
Native to Southern Utah's red rock terrain. Similar to brown recluse but more commonly found outdoors. Can enter homes through gaps around doors and windows.
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.
Brown recluses are less common than black widows in the St. George area but are occasionally found in storage areas, closets, and boxes. Their bites can cause serious tissue damage, making professional identification and treatment important.
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.
