The Three Things You’re Probably Looking For

If you’ve found one in your house, you have one of three problems. Pick the one that fits:

“I think I just got stung — what do I do?”

The 10-minute first-aid protocol, the symptoms that mean go to the ER right now, why bark scorpion stings are different for kids under 5, and how to tell which species stung you. Read this first if anyone has been stung.

“How are they getting in, and how do I stop it?”

The six entry points below account for almost every documented scorpion infiltration in Las Vegas homes:

1. Garage door bottom seals — the rubber gasket compresses, cracks, or stops fully contacting the slab after years of Vegas summers. A 1/8″ gap is plenty.
2. Exterior door sweeps — same problem on every door from your house to the outside.
3. Stucco weep holes — small openings at the base of stucco walls. Direct route from outside the wall into the wall cavity, then into your house through any pipe or wire penetration.
4. Plumbing and electrical penetrations — every place a pipe, cable, or wire crosses an exterior wall has a gap around it, often filled with caulk that’s been failing for a decade.
5. Attic vents and roof eaves — bark scorpions climb walls and enter through unscreened or torn-screen vents. Once in the attic, they drop down through can lights or attic access panels.
6. The roof itself — on tile-roof homes (most Vegas tract housing), scorpions can travel up the wall, under the eave, across the roof, and enter through gaps between tiles.

The full article covers what exclusion measures actually work — and which popular ones (mothballs, essential oils, ultrasonic repellers) are documented to do nothing, no matter what TikTok says.

“What should this cost? Who’s reliable?”

What single-visit treatment, quarterly plans, and premium exclusion packages actually cost in Las Vegas. The red flags in pest-control quotes. When DIY makes sense. How to evaluate whether a $49 special is real or bait pricing.

What This Site Is, and Isn’t

This is an information resource for Vegas residents dealing with scorpions. We compile and source the actual research — Arizona Poison and Drug Information Center protocols, University of Arizona Cooperative Extension data, FDA prescribing info for Anascorp, peer-reviewed pest research — and translate it into something you can act on.

We’re not a pest control company. We don’t dispatch trucks. When you decide you want a professional, we point you toward licensed Vegas operators with verified Nevada Department of Agriculture pesticide application licenses, real customer reviews, and specific scorpion-control experience. We disclose any affiliate relationships clearly. We don’t accept payment to recommend a company.

The Two Vegas Scorpion Species (30-Second Briefing)

Bark Scorpion (Centruroides sculpturatus): 2-3 inches, light tan, thin pincers, climbs walls and ceilings. The only Vegas-area scorpion whose sting is medically significant — particularly to children, the elderly, and immune-compromised people.

Stripe-Tailed Scorpion (Paravaejovis spinigerus): 2-2.5 inches, darker tan-brown body with visible stripes on the tail, thicker pincers, doesn’t climb. Sting is painful but rarely medically dangerous to healthy adults.

If a scorpion is on your wall or ceiling, it’s almost certainly a bark scorpion. If it’s on the ground, it could be either, and the stripe-pattern on the tail will tell you which.

Active Season in Las Vegas

Bark scorpions are active April through October, with peak activity May through September when nighttime temperatures stay above 70°F. November through March they’re largely dormant — hidden in walls, under rocks, and in attics, but not actively hunting. If you’re reading this between May and September, you’re in peak season.

Emergency Numbers

• Poison Control (24/7, free): 1-800-222-1222
• 911 for severe symptoms — slurred speech, breathing trouble, muscle twitching, or any sting in a child under 5 with developing symptoms

Vegas emergency rooms equipped to treat severe scorpion envenomation include Sunrise Hospital, University Medical Center, Summerlin Hospital, and St. Rose Dominican Siena. Not every ER stocks Anascorp antivenom — call ahead if you’re driving in with a serious case.
