Types of Spiders in Utah

So what spiders actually live in Utah? Correctly identifying which Utah house spiders are in your home is crucial in order to begin the most effective treatment for that particular species.

Hobo Spiders

First, the hobo spider. These funnel spiders are some of the most common spiders you’ll see in Utah homes. The arachnid community currently is debating over whether or not hobo spiders are in fact dangerous to humans. Once believed to have a venomous bite that killed skin tissue and formed painful lesions, hobo spiders are now off the venomous spiders’ list due to recent studies.

Nevertheless, these aren’t the friendliest spiders to have in your home. They move quickly and stay close to the ground where children and pets are more likely to find them. However, they won’t attack unless their territory is threatened.

One clear sign of hobo spiders are their funnel-shaped webs. These webs can sometimes be confused with similar funnel webs made by grass spiders, although these are usually found outdoors.

Hobo spiders also can sometimes be misidentified as brown recluse spiders, which are dangerous to humans, but do not live in Utah. The hobo spider can be recognized by their hairy-looking and solid-colored legs, often light brown or rusty red. They also have a unique marking on their abdomen that resembles a herringbone pattern that forms recurring V shapes.

Black Widow Spiders

Perhaps the most well-known spider, black widow spiders are notorious for their venomous bite that can cause serious health complications. After being bitten by a black widow spider, you may experience nausea, difficulty breathing, aching muscles, lightheadedness, a high fever, and/or other symptoms. Visit a doctor as soon as you can to receive proper medical treatment for this dangerous bite.

Most people recognize black widows from their black color and a red marking on the underside of their abdomen in the shape of an hourglass. You may see the red hourglass if the spider is hanging upside down in its web, often messier than other spider webs.

Don’t go without black widow pest controlin your Utah home, especially in cluttered and secluded areas such as storage closets, garages, and woodpiles. Black widow spiders will make their way into your house as the weather begins to cool down, so have the proper protection in place before winter hits.

Bold Jumping Spiders

In Utah, the jumping spider you may come across is the Phidippus audax spider, or bold jumping spider, aptly named for its daring jumping ability despite its small size. These black spiders in Utah grow to about .25” to .5” in length.

Most spiders on this list are nocturnal, but ground spiders are an exception to that norm. As such, homeowners generally find them near window sills, doors, or other well-lit areas.

You’ll notice their small size and quick jumps, but you may also notice other physical features. Look for their green chelicerae or pincers in front of their mouths, large eyes, and black and white coloring. Bold jumping spiders are playful and harmless to humans, but contact a medical professional if you do experience swelling, nausea, or other allergic reactions to a spider bite.

Wolf Spiders

Wolf spiders most often are dark brown in color with lighter markings along their abdomen and legs. They get their name from their agile hunting skills. Rather than spin webs to catch their prey, wolf spiders run quickly before grabbing hold of their dinner. Swift and aggressive when attacking other pests, many people find the appearance of wolf spiders in their home alarming.

These spiders can tend to be hairier and larger than other spider species in Utah. They can grow to be as large as 1 ⅜”. But despite their size and quick speeds, wolf spiders are not dangerous to humans.

Once inside, it can be difficult to remove wolf spiders. But the right professional pest control experts can help place spider traps in the wolf spider’s habitat and apply other spider control treatments.

Yellow Sac Spiders

While their bite is not dangerous, yellow sac spiders tend to be more aggressive than other species. They may bite a human more than once in an attempt to defend themselves which can be painful. The area may become inflamed and fill with an oozing substance.

Frequently found along walls or ceilings, yellow sac spiders are also often found in clothes closets, hiding inside shoes or lingering clothes on the floor. Be cautious, especially if you notice any spider webs nearby.

Yellow sac spider webs resemble small, silken sacs which can be located where walls and/or ceilings meet. Be careful, though; black widow egg sacs can look very similar to these webs.

Crab Spiders

Another yellow spider in Utah is the crab spider, although crab spiders can come in many different colors to blend in with flowers, rocks, trees, and other surroundings. Their eight legs resemble, yep, crab legs which also allow them to scurry sideways.

Like wolf spiders, crab spiders run to attack their prey rather than wait for them to get trapped in a web. Their bite is venomous to small pests, but not to humans, although their speed and camouflaged bodies may frighten some.

A unique trait to crab spiders is that they suck out their prey’s insides through small holes, but leave the rest of the prey’s body once they finish. Small pest carcasses could be a sign that crab spiders are lurking nearby.

Orb-Weaving Spiders

Utah has two common types of orb-weaving spiders that may pop up on your property, particularly in the fall. They are the banded garden spider and the cat-face spider. Both orb-weaving spiders are not a threat to humans and eat many unwanted pests. However, they may invade your home when looking for a place to lay their egg sacs in the months leading up to winter.

Look for orb-weaving spiders’ geometric webs that appear in a circular pattern for identification. Banded garden spiders have beautifully striped bodies and legs that also make them easy to identify, while cat-face spiders have rounder bodies and shorter legs.

Woodlouse Spiders

Woodlouse spiders are distinguishable by their bright red or rust-colored legs and bodies. They have large fangs to eat their favorite prey, the pill bug or rolly-pollies. These bugs are a type of wood louse which is where the spider gets its name.

These fangs can make their bite painful, but not dangerous to humans unless you experience an allergic reaction. Their abdomens also have an easily noticeable tan color in contrast with the rest of their body.

Ground Spiders

You may not find too many ground spiders inside your home as they prefer outdoor habitats. But like other spider species, they may seek shelter inside once the weather cools down before winter.

Like their name implies, ground spiders remain close to the ground to live and find their prey. Their silk webs won’t be large and generally are used for keeping eggs safe and fortifying a shelter, which often will be under a pile of leaves, rocks, wood, etc.

Should they make their way into your home, ground spiders may climb on ceilings and walls, but they do not have a dangerous bite to humans.

Cellar Spiders

Sometimes confused with the arachnids known as daddy longlegs, cellar spiders have long and thin legs attached to a smaller abdomen than most of the Utah spiders on this list. These spiders are not dangerous, but may become a nuisance once they start spinning webs in corners and crannies around your home.

As the name suggests, you’ll find these spiders in dark spaces such as cellars, basements, or attics. What will attract cellar spiders even more is if the area is cooler than the rest of the house and slightly moist or damp. Consider having a pest control company inspect these secluded corners in your house to seal up cracks or gaps where spiders may be getting inside.

Frequently Asked Questions about Spiders

Are spiders nocturnal?

Generally, most spiders will be more active at night. That’s not to say that all Utah spiders are nocturnal, but a large majority are. They will often keep to their webs or the dark corners of your home until nightfall.

However, you may still see spiders up and about during the day. They may do so if they feel that their eggs or habitat are being threatened, or if their prey is more active during the day. If the pests that spiders feed on are diurnal, then the spiders themselves will adapt their sleeping patterns so that they don’t miss out on their next meal.

Can spiders swim?

Many homeowners wonder if they can drown a spider or flush it down the toilet, or if spiders are good swimmers. With the exception of a few species such as diving bell spiders that survive underwater using air bubbles, spiders do not swim. You may have seen some species run across water, but these also are not the best of swimmers and won’t often make an appearance in your Utah home.

Can spiders jump?

It’s true that many house spiders in Utah can jump, sometimes up to 20 times the length of their body in the case of jumping spider species. This can alarm many people, but it’s comforting to know that the bite of a jumping spider isn’t harmful to humans unless you experience an allergic reaction.

Other Utah spiders that do have more dangerous bites to humans are quick movers, but in most cases will not jump and not at such considerable distances.

When and where do spiders lay eggs?

A hidden spider egg sac can turn into a massive infestation quickly with 300 or so eggs filling a single sac. That is, unless you are able to remove the sacs before the eggs hatch. The answer to when and where spiders lay eggs will depend on the spider species in your house. Hobo spiders, for instance, one of the most common house spiders in Utah, will lay eggs in the autumn. Their mating season generally falls around September to October when you may notice an influx of spiders making their way into your home.

As for the location of the egg sacs, some spiders, like wolf spiders and cellar spiders, actually carry their egg sacs with them. Other spiders, like black widows, will leave their egg sacs near their webs or nest. You can vacuum up any egg sacs you see as long as you empty the vacuum bag and trash immediately. But your best chance for removing egg sacs completely and your best defense against spiders laying eggs in your home in the first place are professional spider control services.

Are spiders dangerous?

Again, some spider species are dangerous while others are just your friendly neighborhood spider. Wondering which Utah spiders are dangerous? While many of the spider species mentioned above have painful and venomous bites, most are not considered dangerous to humans. Younger children and older adults, however, may experience more extreme reactions to a spider bite and should seek medical help if symptoms like nausea, difficulty breathing, or ongoing headaches persist or worsen.

Be sure to watch out for black widow spiders. These are perhaps the most dangerous spider in Utah that you might encounter. Brown recluse spiders also have a wicked bite that’s been known to cause serious health reactions, but these reside predominantly in southern Utah. Brown recluse spiders often get confused with hobo spiders, which also have painful bites, but will not put your health in danger. Other Utah spiders that may leave painful bites, but that are not dangerous, include yellow sac spiders and wolf spiders.

In the chance that you are bitten by a poisonous spider, clean the wound and pay careful attention to how your body reacts to the bite. You may suffer from an allergic reaction which in turn could be life-threatening if medical attention is not sought immediately.

What Attracts House Spiders?

Why are so many spiders coming into your house in the first place? To answer that, think about the basic necessities we as humans need. Spiders and other pests require the same bare necessities: shelter, food, and water. Their nature (and our own) is to seek out a place that provides these indispensable essentials.

Should your house offer one or more of these necessities, chances are that spiders will come searching for a way inside. They have acute senses to locate shelter, food, and water sources, meaning that you need to do everything in your power to cut off such sources.

Shelter

Evaluate if your home offers good shelter and protection for spiders. Is there an abundance of dark, warm spaces that keep them out of the cold in winter, while also keeping them out of sight from you?

Basements, attics, garages, closets, and cupboards all are notorious for housing spiders because of the hidden shelter they provide. But even before spiders make their way into these indoor sanctuaries, what may first attract them is outdoor clutter. Woodpiles alongside your home, piles of fallen leaves, and overgrown bushes all can give shelter to spiders.

If you’re noticing more spiders on your property, start by decluttering these outdoor areas. Then move your way inside, regularly checking and cleaning less noticed spaces and corners.

Food

Among the most important things that you can clean up are food sources that may be attracting more spiders. Dirty dishes, unsealed trash cans, or piles of crumbs on the floor may not be what spiders feed on, but the pests that this food entices certainly are.

To get rid of spiders, you first need to address any pest problems. Try to keep your home free of filth and food lying out overnight by cleaning up after meals (easier said than done). Make sure food stored away and in trash cans are sealed shut, preferably in strong plastic, metal, or glass containers. The more you can keep ants, flies, and other pests out of your house, the more spiders you will keep away as well.

Water

A large majority of the house spiders you may find in your home prefer to reside in moist spaces. Utah isn’t humid like other states, but there may be certain areas around your property that offer the water sources spiders are seeking.

For instance, standing water might begin to form underneath leaking pipes or outside by a garden hose. Because these areas are often left unattended, spiders may jump at the chance to make these areas their new homes.
