Spring in Arizona is all about blooming desert flowers, warm evenings, and the return of a not-so-welcome seasonal guest: scorpions. These stealthy arachnids become especially active in the spring as nighttime temperatures rise and their prey becomes more plentiful.
If you’re an Arizona homeowner, understanding the seasonal behavior of scorpions—and how to keep them out of your home—is essential for your safety and peace of mind. This article offers the most effective, science-backed scorpion prevention tips for Arizona homeowners, plus insight into why spring marks the official start of scorpion season in the desert.
Why Are Scorpions More Active in Spring?
Scorpions are cold-blooded creatures, meaning their activity levels are tied closely to the outdoor temperature. During winter, they slow down significantly and often remain hidden in warm, dark spaces like wall voids, under rocks, or in cluttered storage areas.
As spring arrives and overnight temperatures start staying consistently above 70°F, scorpions begin to emerge in search of food, water, and new shelter. The Arizona Bark Scorpion, the most common species in the region, becomes especially active this time of year—and it’s also the most venomous scorpion in North America.
According to the University of Arizona’s Integrated Pest Management Program, scorpions are nocturnal and can enter homes through cracks as small as 1/16 of an inch. They don’t need much of an invitation.
Where Scorpions Like to Hide Around Your Home
Scorpions are masters of hiding in plain sight. Here are the most common hiding spots where they tend to turn up around Arizona homes:
- Under landscaping rocks, logs, or firewood
- In cracks along your home’s foundation or walls
- Inside garage corners, closets, and behind baseboards
- Around potted plants or in garden beds
- Beneath piles of clothes, towels, or cardboard boxes
- Under outdoor furniture cushions or patio umbrellas
If you’ve seen one scorpion, there’s a good chance there are more nearby. Scorpions can travel in groups and often return to the same hiding places each day.
Scorpion Prevention Tips for Arizona Homeowners
Now that spring is here, it’s time to be proactive. Here are the most effective, expert-backed scorpion prevention tips for Arizona homeowners to reduce the chances of an unwelcome encounter:
1. Seal Entry Points
Scorpions can squeeze through incredibly small spaces.
- Use weather stripping on all exterior doors
- Seal cracks in your foundation, stucco, and siding with caulk
- Repair torn window screens and ensure they close tightly
- Install door sweeps on exterior doors, especially to garages
2. Declutter Inside and Out
Scorpions love undisturbed, dark spaces.
- Keep garage floors, closets, and storage areas organized
- Remove piles of clothes, boxes, or towels from floors
- In the yard, eliminate debris piles, stacked wood, and excess leaves
3. Landscape with Scorpions in Mind
Your landscaping choices can either deter or attract scorpions.
- Trim back bushes and trees so they don’t touch your house (scorpions can climb!)
- Use gravel or stone mulch instead of wood chips, which retain moisture and attract insects
- Keep grass well-mowed and avoid overwatering (which attracts scorpion prey like insects)

4. Reduce Their Food Supply
Scorpions aren’t interested in you—they’re after the bugs in your home.
- Use yellow-tinted outdoor lights, which are less attractive to insects
- Eliminate standing water sources where bugs gather
- Treat your home with pest control that targets insects like ants, roaches, and crickets
5. Use Physical Barriers and Traps
- Sticky traps placed along baseboards or in dark corners can help monitor and reduce scorpion presence
- Consider scorpion-proofing your home with mesh screens over weep holes and vents
6. Try UV Detection at Night
Scorpions glow under black light! If you suspect you have them, go outside at night with a UV flashlight to inspect walls, patios, and garden beds.
When to Call a Professional
While DIY steps are helpful, some scorpion infestations require expert intervention. You should call a professional pest control service if:
- You see multiple scorpions in or around your home
- You have young children, elderly family members, or pets, who are more at risk from stings
- You’ve already tried prevention but continue to see signs of activity
A pest control professional will not only inspect your home for active infestations but also create a custom treatment plan using targeted products that eliminate both scorpions and their insect prey.
For homeowners concerned about safety, look for companies that use eco-friendly and pet-safe treatments, like we do at Primo Pest Control.

Are Scorpions Dangerous?
While not all scorpions pose a serious health threat, the Arizona Bark Scorpion does. Its sting can cause numbness, difficulty breathing, and severe pain, especially in small children or those with allergies.
If someone is stung and shows signs of a severe reaction, seek immediate medical attention. According to the Mayo Clinic, most stings only require basic first aid, but symptoms should be monitored closely.
