Pest Control
The Scottsdale Homeowner's Guide to Scorpion Control
Apr 15, 2026 · 6 min read
If you live in Scottsdale or Paradise Valley, you will encounter scorpions. The Arizona bark scorpion is the most common species in the area and the most venomous scorpion in North America. While rarely life-threatening to healthy adults, their sting is extremely painful and can be dangerous for children, elderly residents, and pets.
Why Scottsdale Has a Scorpion Problem
Scottsdale sits in prime bark scorpion habitat. These arachnids thrive in the rocky, desert terrain of North Scottsdale, Paradise Valley, and communities near the McDowell Mountains. New construction that disturbs their natural habitat pushes them toward homes. They're also attracted to water sources — your pool, irrigation system, and any standing water become magnets.
Prevention: Sealing Your Home
Scorpions can squeeze through a gap as thin as a credit card. The most effective prevention starts with sealing entry points. Focus on the gap under exterior doors and garage doors, weep holes in block walls, cracks in the foundation, openings around pipes, conduit, and wiring, and gaps in window screens.
A professional pest control company can do a full home seal that dramatically reduces scorpion entry. This typically costs $200-500 and is one of the best investments you can make for a Scottsdale property.
Professional Treatment Options
Regular pest control treatment creates a chemical barrier around your home that kills scorpions on contact. Most Scottsdale pest companies offer monthly or bi-monthly service plans ranging from $40 to $80 per visit. The most effective programs combine exterior barrier spraying, targeted treatment of common entry points, granular treatment in landscaping and rock areas, and dust application in wall voids and attic spaces.
The Blacklight Test
Bark scorpions glow bright blue-green under ultraviolet light. Grab a UV flashlight and walk your property's perimeter after dark. This will tell you exactly how active scorpions are around your home and where they're congregating. If you're seeing more than a couple per inspection, it's time to call a professional.
