Spiders in St George Utah

Utah has almost 4000 different species of spiders; however, only a small portion are dangerous. The vast majority are harmless and do not pose any danger to humans.

Common Spiders in Utah

To help you identify what spider you are dealing with, I put together this short guide to the most common spiders that can be found in Southern Utah.

Hobo Spider

The aggressive house spider, or western hobo spider, is found throughout Europe and Asia. Unfortunately, they were accidentally introduced to the Northwestern United States in the 1980s. Fortunately, they are found primarily in Washington state. Hobo spiders belong to the family Agelenidae, a group of arachnids known for their funnel-like web construction. They spin horizontal layers of entangled silk threads that serve as nests, detection devices, and traps for potential prey. Male hobo spiders are more likely to bite humans because they roam around in the open more often than females, so they encounter humans more often than females do.


These medium-sized spiders have a dark brown color and long legs.

They also possess two large palpi (mouth parts) that look like boxing gloves, making it easy to distinguish the male from the female.

Additionally, females tend to have a larger and rounder abdomen when compared to males.  Wolf Spiders are solitary hunters at night, so they will most likely be in hiding during the daytime hours.

The wolf spider can produce a defensive bite if handled, but this is not believed to cause serious injury or death; however, some individuals may experience mild symptoms such as itching and localized swelling around the bite area which should ease within several days without further action being required on your part.

Their abdomens have several chevron shaped markings with yellowish legs, eyes that appear black with red pupils under white fangs viewed from above give them an eerie appearance! Image Hobo Spider Image Hobo spiders are more likely than other kinds of wild spiders to enter homes because

Banded Orb Weaver

There are many kinds of orb weaver spiders. They vary in color, size, shape and pattern. One kind of orb weaver spider is 2 to 3 centimeters long for the female and about 1.5 cm for the male body length. The adults usually have a brown or grey body with a stripe on it, which may be white or brown edged with white. They also have two humps on their bodies, one up front and one at the back of their abdomen, called "chelicerae". Despite these intimidating features, they are not harmful unless provoked.

Ground Spider

Ground Spiders are hairy, brown spiders that live on the ground. They prefer to inhabit areas with thick vegetation and open terrain, such as a meadow or woodland area. Ground spiders rarely venture from their homes, except to hunt for food at night and during the evening hours.

Poisonous Spiders in Utah

While there are many common spiders in Southern Utah, such as the black widow and recluse spider, these two are much more dangerous.

Black Widow

The black widow spider is one of the most venomous spiders found in North America. The female black widow bite can be deadly to small children and adults, so it's important that you seek medical attention immediately.

Desert Recluse Spider

This is definitely one I hope I don’t come across! They are usually a tan to dark brown color and 1/4 – 1/2 inch long. The desert recluse is known for the fiddle-shaped marking on its back. One of their tell-tell features is that they have 6 eyes instead of the normal 8.  They tend to stay away from populated areas, they like the outdoors and are found in pack rat dens. The Desert Recluse is highly venomous! In the event that you are bitten by one of these poisonous spiders seek medical attention and if possible bring them with you as well

Spider Control and Prevention 

If any of these spiders have found their way into your home or garden shed, the best way to control their presence is by removing their source of food. Spiders primarily eat other insects, so reducing the presence of other pests in your home will make spiders less interested in invading your home.

When you place the spider eggs on a newspaper or cardboard egg carton, you can use a piece of paper to prevent them from drying out, as it may kill them and hatchlings if they are still moist. If hatched spiders are still damp, they will crawl away and hide because they do not know how to walk yet and don’t want to be eaten. Be sure that no one is around when you remove them from the egg cartons with forceps. You can collect some adult female moths that have emerged from these eggs after sitting for 30–45 days, depending upon weather conditions and temperature. The moth larvae will pupate within 2–3 days, then you should see winged adults emerge after another 30–45 days (up to 60 days). The easiest method for killing all stages, including baby moths is by lightly blowing air over an area or using a stream of water directed at an area where there are moths flying around, this will result in deaths immediately without taking much effort.
