Slab foundations are common across the Las Vegas valley, from Summerlin and Centennial Hills to Green Valley and Anthem. Structural features and exterior gaps often serve as entry routes for scorpions. The Arizona bark scorpion is the only scorpion in Nevada with venom of real medical significance. It can climb walls and ceilings, and it can squeeze through a gap about as thin as a credit card. Small structural openings around exterior walls allow scorpions to enter the living space. Knowing where they enter helps us create a targeted treatment plan for your home.
Weep screens along stucco walls
Stucco homes built on concrete slabs feature weep screeds along the bottom edge of exterior walls. The open gap between the bottom of the stucco and the foundation slab often leaves open pathways behind the wall cladding. Weep screeds and weep screens at the base of stucco walls on slab homes are a common entry route for scorpions and cockroaches unless sealed or screened. Without proper weep screen guards installed, scorpions climb up the concrete slab edge and enter these spaces.
Exterior doors and doorways
Exterior doors, garage entry doors, and sliding glass doors create entry points. A slight gap at the bottom corner of a door frame creates more than enough space for a scorpion to crawl under. Installing sturdy door sweeps provides a tight seal along exterior doorways to reduce these floor level openings. Whiptail installs door sweeps to help block scorpions from coming inside.
Plumbing and wiring penetrations
Utility lines entering through exterior walls create additional entry points on slab homes. Common wall penetrations include several specific structural areas:
- Air conditioning refrigerant lines entering lower exterior walls
- Outdoor hose bibs and exterior plumbing pipes
- Electrical conduit and outdoor lighting wire runs
- Cable lines and utility service entrances
Unsealed gaps around these penetrations give scorpions direct access into the structure. Sealing these gaps is a central part of limiting their movement.
Exclusion work and exterior treatments
Sealing reduces entry points and works alongside targeted exterior treatments. We offer structural exclusion services, including the installation of door sweeps, weep screen guards, and durable sealing around exterior plumbing and wiring penetrations. Our technician inspects inside and outside, finds entry points and the conditions supporting the scorpions, and explains what they found. Estimates for general pest service are free, and you review the recommendation and approve the price before any treatment or exclusion work begins. We provide an exterior treatment where scorpions hide, focusing on block walls, gravel, and weep screens. For ongoing service, our Scorpion Plan includes a blacklight night inspection at the start, exterior visits every two months, and free re-service between scheduled visits if covered pests return. The plan also covers ants, cockroaches, spiders, crickets, earwigs, silverfish, centipedes, and pill bugs.
Prevention steps for homeowners
Customers have a role in reducing scorpion activity around the yard. Trimming plants off the house and keeping gravel and woodpiles away from the house helps reduce hiding spots. Keeping garages tidy and fixing leaks and moisture are also customer responsibilities. While prevention alone does not end an active infestation, it is an important step. Before we treat your property, we supply written preparation and reentry instructions. The written instructions dictate reentry times, and the customer, not our staff, keeps children and pets out of treated areas.
Scheduling a property inspection
If you notice scorpions indoors in a home with small children, please call our office directly instead of using the online form. The office fits urgent calls in when a technician is available. For other pest control needs, requests sent through the website are answered during business hours, usually the same business day. We schedule visits across the Las Vegas valley, including Enterprise and Sunrise Manor. To learn more about our structural exclusion options or to request a visit, go to our scorpion control page.
