Discover the Most Common Spiders Found in Wyoming

Wyoming, known for its breathtaking landscapes and rugged Western charm, is also home to various spiders. From harmless household spiders to the more intimidating venomous ones, these arachnids are integral to the state’s ecosystem. While many of these spiders help keep insect populations under control, others may warrant caution or even professional pest control.

Here’s a closer look at the most common spiders in Wyoming and how to manage their presence.

Key Takeaways

• Wyoming has a mix of harmless spiders like orb weavers and venomous ones like black widows, often found indoors.
• Managing spider issues starts with sealing gaps, reducing clutter, and cleaning regularly to remove webs and pests.
• Professional pest control best handles venomous spiders or large infestations to ensure safety and peace of mind.

The Most Common Spiders in Wyoming

Whether hiking through Wyoming’s grasslands or tidying up your basement, chances are you’ll cross paths with a few of the state’s eight-legged residents.

Let’s take a closer look at these spiders you’re most likely to spot in Wyoming:

Wolf Spiders

Wolf spiders, members of the Lycosidae family, are frequently found in Wyoming’s grasslands and around homes. These hunting spiders don’t spin webs but instead rely on their agility and sharp eyesight to catch prey.

With their long legs and camouflaged coloring, wolf spiders blend into the terrain. Although their bite can be mildly irritating, it’s not dangerous unless you’re allergic.

Black Widow Spiders

The Western Black Widow spider (Latrodectus hesperus) is a well-known venomous spider that thrives in Wyoming. Recognized by its black body and red hourglass marking, this arachnid often hides in basements, woodpiles, and dark corners.

A black widow spider bite can cause significant discomfort, including muscle cramps and nausea, though fatalities are rare in the USA. If you spot one, avoid handling it and seek professional assistance.

Jumping Spiders

Jumping spiders, such as the bold Phidippus audax, are among the most fascinating spiders in Wyoming. Known for their energetic movements and excellent vision, they often sport colorful markings that make them stand out.

These spiders are non-venomous and pose no threat to humans. They’re more likely to entertain you with their antics than cause any harm.

Hobo Spiders

Hobo spiders (Eratigena agrestis) have gained notoriety in the Western United States, including Wyoming and nearby states like Montana and Colorado. Often confused with other funnel-web spiders, they create dense, tubular webs in grass or basements.

Although their venom was once associated with necrotic wounds, recent research suggests their bites are no more harmful than those of a common house spider.

Orb Weavers

Orb weavers, including the striking cat-faced spider, are easy to spot by their large, intricate webs in gardens and wooded areas. These spiders, while intimidating in appearance, are non-venomous and crucial for controlling pests like grasshoppers.

If you’re a fan of outdoor photography, orb weavers make excellent subjects with their cephalothorax shining in the sunlight.

House Spiders

The common house spider (Parasteatoda tepidariorum) is one of the most frequent arachnids found indoors in Wyoming. Known for spinning cobwebs in dark corners and basements, these spiders help control flying insects but can be an annoyance when their webs accumulate.

Funnel Weavers

Funnel weavers, like the grass-dwelling Agelenidae species, are speedy arachnids often spotted in yards or basements. They create funnel-shaped webs to trap prey and dart out to capture it.

Though their appearance can be alarming, they are non-aggressive and pose no significant threat.

Tips for Spider Prevention and Control

To manage spiders in your home or property, follow these preventive measures:

• Inspect your home for gaps around windows, doors, and foundations.
• Reduce clutter since they often hide in woodpiles, basements, or storage areas.
• Use natural deterrents like essential oils without harming the environment.
• Limit outdoor lighting: It can attract insects, which, in turn, attract spiders.
• Vacuum and clean areas where spiders might build webs.

For severe infestations or the presence of venomous spiders like the Western Black Widow, professional pest control services are the safest option.
