Bark scorpions are one of the most feared pests in Arizona. As the most venomous scorpion species in North America, their stings can be extremely painful. And potentially dangerous for children and pets. Homeowners in areas like Tempe, Chandler, Phoenix, and the greater Maricopa County need to stay vigilant and take proactive steps to keep these pests out of their living spaces.
In this comprehensive guide, we’ll walk you through everything you need to know about bark scorpions. From identifying them to preventing them from entering your home. If you’re serious about protecting your family and property, these expert-backed tips are a must.
What Are Bark Scorpions?
Identification and Appearance
The Arizona bark scorpion (Centruroides sculpturatus) is a small and tan-colored scorpion. They are typically about 2.5–3 inches in length. Its slender body and tail distinguish it from other less dangerous scorpion species found in the Southwest. One of its most unique characteristics is its ability to climb walls, ceilings, and even hang upside down.
Where Are They Found in Arizona?
Bark scorpions thrive in Arizona’s hot and arid environment. Especially in and around Maricopa County. They are nocturnal, hiding during the day in cool conditions. They also hide in shaded areas such as under rocks, in tree bark, behind baseboards, or inside closets. They become more active in the spring and summer when nighttime temperatures rise.
Are Bark Scorpions Dangerous?
Yes. While a sting is rarely fatal to healthy adults, it can cause extreme pain, swelling, and numbness. And even temporary paralysis. Children, the elderly, and those with allergic reactions may experience more severe symptoms.
Why Bark Scorpions Enter Homes
Common Entry Points
Bark scorpions can slip through openings as small as 1/16 of an inch. They typically enter homes through:
- Gaps under doors
- Cracks in the foundation or stucco
- Vents and weep holes
- Utility entry points (cables, pipes, AC units)
What Attracts Them?
Scorpions are drawn indoors when outdoor temperatures become too hot or too cold. They also enter homes in search of food (insects like crickets and cockroaches) and water. High humidity, standing water, or excessive indoor clutter can make your home more attractive to them.
How to Keep Bark Scorpions Out of Your Home
Fill in all the cracks
Start by thoroughly inspecting your home’s exterior:
- Use silicone caulk to seal any gaps or cracks around windows, baseboards, pipes, and vents.
- Install door sweeps and weather stripping on all exterior doors.
- Replace or repair torn window screens.
- Use mesh screens over attic vents and weep holes.
Store food properly and fix leaks
Scorpions follow the food. Eliminate their prey by:
- Keeping your kitchen and pantry clean and crumb-free.
- Storing food in airtight containers.
- Fixing leaky faucets or pipes that provide moisture.
- Using dehumidifiers in damp areas like bathrooms or basements.
Pest-proofing your home against other bugs automatically reduces scorpion activity.
Make your yard less inviting to pests
Scorpions hide in dark, cool areas during the day. Common hiding spots include:
- Firewood piles
- Garden debris
- Rock piles
- Landscaping timbers
Use Scorpion Repellents and Barriers
Natural deterrents like cedar oil or diatomaceous earth can repel scorpions when applied around baseboards and entry points. For added protection:
- Install physical scorpion barriers around doors and windows.
- Use sticky traps in areas with suspected activity.
While repellents can help reduce activity, they are no substitute for comprehensive pest control services.
Blacklight Night Inspections
Bark scorpions glow under UV light. Conducting nighttime inspections with a blacklight flashlight can help you spot them in their hiding places along walls, under furniture, or in closets.
Professional Scorpion Control Solutions
What Pest Control Companies Do Differently
Professional pest control services target both scorpions and their food sources. Technicians apply long-lasting, scorpion-specific products in strategic areas such as:
- Perimeter of your home
- Cracks and voids
- Behind appliances and furniture
- Attics and crawl spaces
Benefits of Regular Scorpion Treatments
Scorpions are resilient, and over-the-counter products often aren’t strong enough. Ongoing professional treatments offer:
- Consistent prevention and monitoring
- Safe and effective chemicals
- Peace of mind for your family and pets
Is Your Home at Risk for Bark Scorpions?
Risk Factors in Maricopa County Homes
Your home may be at higher risk if:
- You live near desert preserves or open fields
- Your yard contains large rocks or woodpiles
- You’ve had previous pest issues (crickets, roaches)
- Your home has unsealed utility gaps or vent openings
