Can you get rid of pests without putting your pets at risk? Many of you have asked: Is diatomaceous earth safe for dogs? What about cats? The short answer: Yes—when it’s food-grade and used correctly. Let’s explore how to use it safely.
What is diatomaceous earth?
Diatomaceous earth (DE) is derived from the fossilized remains of tiny, aquatic microorganisms called diatoms. These skeletal remains are mostly made of silica. Though humble in origin, DE is a powerhouse for controlling crawling insects. It punctures their exoskeletons and dehydrates them—no harsh chemicals required.
What makes DE particularly appealing is its versatility. It can be used in your garden, your kitchen, your garage or on your pet's bedding. It is even used in some food applications to control internal parasites.
Is diatomaceous earth safe for pets?
Yes, food-grade diatomaceous earth is generally safe for pets—including both dogs and cats—when used with a few precautions:
- Use only food-grade DE – Pool-grade DE is chemically treated and hazardous.
- Avoid inhalation risks – The fine powder can irritate respiratory systems.
- Apply carefully – Minimize airborne dust.
- Keep water and food bowls covered – Do not let DE settle into pet food or water.
- Monitor sensitive pets – If your pet has respiratory issues, be cautious.
Used mindfully, DE can be a safe, natural pest control solution—without harming your pets.
How to use diatomaceous earth for dogs and cats—safely
Be sure to follow the product’s application instructions. While DE is safe for pets to ingest in small amounts—some even use it as a dewormer—avoid leaving piles of it around, as larger quantities may cause digestive issues.
For added precision and reduced airborne dust, use the Insect Buster. This applicator helps target problem spots while minimizing mess and exposure.
Why choose pet-safe insect control options?
Why opt for DE or other pet-safe insect killers? Beyond the obvious benefit of being safe for pets, it's also non-toxic and eco-friendly. This means you don't have to worry about harmful chemicals seeping into your soil or contaminating your home environment.
For a ready-to-use spray alternative, consider Six Feet Under Plant-Powered Insect Spray. Made from a proprietary blend of clove, cinnamon and soybean oils, this non-toxic solution kills insects on contact and offers residual protection. It's effective against ants, cockroaches, moths, houseflies, silverfish, weevils, fleas, ticks, mites, earwigs and more.
Prefer a powder? Dust to Dust Plant-Powered Insect Powder is a powerful DIY solution that works similarly to DE—but with enhanced effectiveness. Its nano-tech essential oils and fine silica particles penetrate insect exoskeletons, dehydrating them without harming pets or people. It can be applied the same way you’d use DE.
Conclusion
When used correctly, diatomaceous earth for cats and dogs is a safe, natural and effective way to control pests without harming your furry companions. As with any form of pest control, the key is to use it wisely and carefully, following all manufacturer guidelines. And always remember, food-grade is the way to go when using DE in a household with pets.
Stay enlightened. Stay protected. And give your pets an extra cuddle from me.
