It feels backward. You bought a brand-new home and within a month you are finding scorpions on the wall. The newness is exactly why, and the fix is more about sealing than spraying.
Every new tract in the valley used to be raw Mojave. Bark scorpions, crickets, and the insects they hunt lived in that soil long before the foundation went in. When the grader scraped the lot flat, it did not remove that population. It scattered it. The displaced scorpions move toward the nearest shelter, moisture, and food, and once your home is standing, that is your home.
This is why the desert-edge neighborhoods see it worst. A new build at Henderson’s Inspirada or the Anthem foothills, or up in North Las Vegas at Aliante and Valley Vista, sits right on the boundary between finished homes and undisturbed land. The scorpions keep walking in off the open desert until that boundary is sealed and the food source on your side of it is gone.
New construction scorpion pressure peaks early, then usually settles. The first reason is the surrounding lots. While the rest of the tract is still being graded and built, every round of earthmoving displaces more scorpions toward the homes that are already finished, yours included. As the neighborhood fills in, that churn stops.
The second reason is your own yard. A new build starts with bare dirt, then gets rock, irrigation, and young plants. Fresh irrigation in a desert yard is a magnet: it brings water, water brings crickets and other insects, and those insects bring the scorpions that eat them. Until your perimeter is sealed and the food source is under control, the new oasis you just built is feeding the exact problem you are trying to solve.
This catches a lot of new homeowners off guard. A builder builds to code, and code says nothing about keeping a flat-bodied scorpion out. The gaps that let them in are all standard construction:
None of these are defects. They are just how homes go up. Closing them is exclusion work, and it is the part of scorpion control that actually keeps a new home clear long term.
Spraying alone will not do it. A baseboard treatment kills the scorpion you can see and ignores the open weep screed feeding the next ten. Real control on a new home works on two fronts at once: cut the food source and seal the perimeter.
Cutting the food source means treating the insects scorpions hunt, the crickets and other prey gathering around your new irrigation and exterior lights. Sealing the perimeter means closing the weep screed entry points, the garage gaps, and the utility penetrations so the scorpions outside cannot keep getting in. We pair that with a blacklight inspection at night so you can see how many are actually on your walls, since scorpions glow blue-green under UV. New homeowners are usually shocked by the count, and it makes the case for sealing better than anything we could say.
For a new desert-edge home, a recurring plan usually beats a one-time visit, at least through those first summers. The pressure from surrounding construction and a settling yard does not resolve in a single treatment, and a maintained perimeter is what keeps the barrier intact while the neighborhood stabilizes. Recurring scorpion plans usually run $100 to $150 per quarter, against $150 to $300 for the first visit.
We do not lock you into a long contract to get there. Plans run quarter to quarter, and once the neighborhood fills in and the pressure drops, you can step down or cancel. If you want to compare what one-time versus recurring looks like for your situation, the cost guide lays out both, and the FAQ page covers what a scorpion visit includes.
Your lot was open Mojave desert until recently, and grading displaced the scorpions that lived there. They move toward the nearest shelter and water, which is now your home. New stucco also leaves open weep screeds and unsealed gaps the builder did not seal, so the scorpions walk right in. It is common and it is fixable.
The first two summers in a new desert-edge home tend to be the worst, while the surrounding lots are still being graded and the local population is unsettled. Once the neighborhood fills in and your perimeter is properly sealed and treated, the pressure usually drops. A maintained quarterly plan is what keeps it down.
No. Builders meet code, not pest exclusion. Weep screeds, garage door corners, utility penetrations, and expansion gaps are all left as designed, and any of them is wide enough for a flat bark scorpion. Closing those gaps is exclusion work a pest control crew does, not something included in the build.
A first scorpion-specific visit usually runs $150 to $300, with recurring plans around $100 to $150 per quarter. New homes on the desert edge usually do best starting on a recurring plan, since the perimeter needs maintaining through the first summers. See our scorpion control page or the cost guide.
The new tracts pressed against open desert see the most: Inspirada and the Anthem and Seven Hills foothills in Henderson, Aliante and Valley Vista in North Las Vegas, and The Ridges and newer Summerlin edges near Red Rock. Any new build backing onto undisturbed BLM land is in scorpion country.
We are a licensed, local crew, and a first scorpion visit usually runs $150 to $300. We treat the food source and seal the gaps the builder left, so the desert stays outside where it belongs.
