Scorpions are common pests in places like Arizona, Phoenix, and Texas. They’re not only a nuisance but also a potential safety risk because of their stings. Many homeowners turn to natural solutions like diatomaceous earth to control scorpion infestations. But does it really work?
Let’s explore this natural substance and its effectiveness against scorpions.
Key Takeaways
- Diatomaceous earth kills scorpions by drying them out when they touch the sharp particles.
- Common scorpion spots include cracks, basements, and outdoor areas like woodpiles and under rocks.
- Prevention includes sealing gaps, clearing clutter, and removing insects that scorpions eat.
- Pest control experts can help if scorpions keep showing up after trying home methods.
How Does Diatomaceous Earth Work Against Scorpions?
Diatomaceous earth, often called DE, is a powdery natural substance made from fossilized algae called diatoms. It’s widely used in pest control to kill pests like cockroaches, fleas, and crickets by targeting their exoskeletons.
Like other arachnids, scorpions have a tough exoskeleton.
When they walk through it, the powder’s sharp particles scratch their exoskeleton, causing them to lose moisture and dehydrate. This process eventually kills them, but it’s not immediate—it can take days for the scorpion to succumb.
How to Use Diatomaceous Earth to Get Rid of Scorpions

To prevent scorpion stings, here’s how you can use diatomaceous earth effectively:
Target Key Areas
Scorpions prefer dark, quiet spaces to hide.
Apply DE in areas like cracks, voids, crevices, and basements. Outdoors, treat woodpiles, under rocks, and near your foundation. These are common spots where scorpions hunt for prey and shelter.
Seal Entry Points
Block scorpions from entering your home by sealing gaps around windows, doors, and walls with caulk or weather stripping. Even small cracks can become entryways for scorpions.
Sealing these points also helps keep out insects like crickets and cockroaches, which scorpions feed on, making your home less inviting overall.
Spread DE Correctly
Use a duster to spread a thin, even layer of food-grade diatomaceous earth along baseboards, in cracks, and at entry points. Focus on outdoor areas like rock beds or woodpiles where scorpions might travel.
A proper application creates a lasting barrier that protects your home while being safe for pets and people.
Combine with Other Tools
Pair DE with other tools for better results. Sticky traps catch scorpions, while black lights help you spot them at night, as scorpions glow under UV light. Essential oils, like peppermint oil, act as natural repellents, and boric acid can be used in crevices to deter scorpions.
Together, these tools make it easier to identify and target problem areas effectively.
Reapply When Needed
DE isn’t permanent—it stops working when it gets wet or disturbed.
To keep it effective, reapply after cleaning, rain, or heavy use in treated areas. Regular reapplication ensures a consistent barrier against scorpions and helps keep your home protected over time.
How to Prevent Scorpion Infestations
Preventing scorpions from entering your home is just as important as killing them. Here are some tips to keep scorpions at bay:
- Use pest control methods to eliminate food sources like crickets, termites, and cockroaches.
- Clean up basements, garages, and outdoor areas to remove hiding places.
- Use natural scorpion repellents or professionally applied products.
- Keep woodpiles, debris, and overgrown shrubs away from your home.
