While most spiders are harmless—and even helpful by eating other insects—the sight of one crawling across your floor or hiding in the corner of a ceiling can be unsettling. In Las Vegas, where the warm, dry climate offers the perfect habitat for many arachnids, homeowners frequently encounter a range of common spiders. But how do you know which ones are harmless and which ones require professional attention?
At Pest Raiders, we understand that not all spiders are created equal. Some simply look scary, while others can pose real health risks to your family and pets. This blog will help you identify the most common spiders in Las Vegas homes and let you know which ones to keep an eye on.
Why Spiders Love Las Vegas Homes
Spiders are natural hunters, and they follow their food—typically insects. Las Vegas homes often attract spiders because of other pest activity, cluttered spaces, or moisture-rich environments like bathrooms and kitchens. They also sneak in through cracks, vents, and open windows looking for shelter from the desert heat.
While most spiders prefer to stay hidden, infestations can occur if they find consistent food and nesting areas inside or around your home.
1. Cellar Spiders (Daddy Longlegs)
These are among the most common spiders you’ll see in Las Vegas. Recognizable by their long, thin legs and small bodies, cellar spiders typically hang out in basements, garages, and closets. Despite their creepy appearance, they are completely harmless to humans and pets.
Watch level: Low
Danger level: None
2. American House Spider
This small, tan or gray spider is known for creating messy, tangled webs in corners, under furniture, and around ceilings. While they’re unsightly and their webs can be annoying, they are not aggressive and rarely bite.
Watch level: Low
Danger level: None
3. Wolf Spiders
These large, fast-moving spiders don’t build webs. Instead, they hunt their prey on foot. They can be alarming due to their size and speed, and they’re often mistaken for more dangerous species. Wolf spiders can bite if threatened, but their venom is not considered dangerous to humans.
Watch level: Moderate
Danger level: Low
4. Jumping Spiders
Small, compact, and often colorful, jumping spiders are known for their curious behavior and sudden leaps. They usually don’t spin webs, preferring to roam around windowsills and walls during the day. Their bite is rare and harmless.
Watch level: Low
Danger level: None
5. Desert Recluse Spider
Here’s where you need to be more cautious. Often confused with the more well-known Brown Recluse, the Desert Recluse is native to the Southwest and can be found in some parts of Las Vegas. These spiders are light brown with a violin-shaped mark on their back and tend to hide in dark, undisturbed places like attics, closets, and under furniture.
Their bites can cause serious reactions in some individuals, including skin necrosis and infection. While not aggressive, they will bite when disturbed.
Watch level: High
Danger level: Moderate to Severe
6. Black Widow Spider
The Black Widow is one of the most dangerous common spiders found in Las Vegas. Easily identified by its shiny black body and red hourglass marking, this spider prefers garages, woodpiles, sheds, and outdoor furniture.
A bite from a Black Widow can cause intense pain, cramping, and nausea. Medical attention is advised for any suspected bites, especially in children, the elderly, or those with compromised immune systems.
Watch level: Very High
Danger level: Severe
