Las Vegas does have scorpions, and one species is worth taking seriously. This guide covers which scorpions live in the valley, where they are most common, how to check your own yard, and what actually works to keep them out of your home.
Las Vegas sits in the Mojave Desert, and scorpions have always lived here. Every neighborhood in the valley has them to some degree. Most of the time you'll never notice — scorpions are nocturnal, they spend the day inside block walls and under rock landscaping, and they avoid people when they can.
The reason scorpions are a serious topic in Las Vegas comes down to one species: the Arizona bark scorpion. It is the only scorpion in the United States whose sting is medically significant, it climbs walls, and it can fit through a gap about the width of a credit card. That combination is why it ends up inside houses, and why finding one in a bathtub or sink is such a common experience for valley homeowners.

Scorpions concentrate where the desert meets new construction. When land is graded for a new development, the scorpions that lived there move into the nearest block walls, rock landscaping, and garages. That is why the busiest scorpion areas are usually the newer neighborhoods at the desert edge: Summerlin's newer villages, Anthem and Inspirada in Henderson, Skye Canyon, Providence, and Mountain's Edge all see steady scorpion activity. Established neighborhoods with mature landscaping have them too — especially yards with river rock, wood piles, or citrus and palm trees.
Around a house, the most common hiding places are:
Scorpions in Las Vegas are most active from roughly April through October, with the heaviest activity in the hot months. They hunt at night when the ground cools. In winter they slow down and shelter — bark scorpions sometimes gather in groups inside wall voids, which is why a warm winter day can suddenly produce several sightings at once. Indoor sightings peak in summer, when scorpions follow their prey (mainly crickets and other insects) toward irrigated yards and cool houses.
Every scorpion glows blue-green under ultraviolet light — a trait of their exoskeleton. An inexpensive UV flashlight (around $15) and a slow walk around your yard an hour after dark will show you exactly what you are dealing with. Check the block walls, the base of the house, rock beds, and around the patio. Seeing one scorpion is normal desert life. Seeing several in one walk usually means an established population is living on your property.
This check gives you an honest diagnosis on your own. What it can't tell you is where they are nesting inside structures, which gaps they are using to get into the house, and how to close those routes off — that is what a professional inspection is for.
A scorpion indoors means two things: there is a population living in or near your walls, and there is an entry gap somewhere. Glue traps along baseboards and in the garage will confirm how much traffic you have. The fix that actually works is a combination of three things: sealing the gaps they use to get in (home scorpion sealing), targeted treatment of the areas where they live — block wall voids, expansion joints, rock beds — and reducing their food supply by controlling crickets and other insects around the home.
It's worth knowing that scorpions are unusually resistant to ordinary pesticide sprays, so a spray-only service tends to produce disappointing results. Any experienced scorpion company will tell you the same thing.
A bark scorpion sting causes immediate, intense pain, often with numbness and tingling that can spread. For most healthy adults it resolves over one to three days. For small children, the elderly, and pets it can be serious and needs prompt attention — call the Poison Control Center at 1-800-222-1222, and 911 for severe symptoms. An antivenom exists and Las Vegas hospitals can treat serious cases. For symptoms, first aid, and prevention, see the sting first-aid guide.
