## Description

Say Goodbye to Crawling Insects—Naturally and Effectively. Protect your home and garden with Harris Diatomaceous Earth Crawling Insect Killer, a fast-acting and long-lasting solution to unwanted pests. This 100% pure diatomaceous earth formula is OMRI Listed for organic use and contains no additives or fillers, making it a safe, non-toxic option for families with pets and children (when used as directed). This 4lb bag includes a convenient powder duster, allowing you to apply the powder with precision in hard-to-reach areas like baseboards, cracks, behind appliances, and around foundations. It’s a mechanical insecticide—not a chemical one. When insects like ants, bed bugs, cockroaches, fleas, silverfish, earwigs, and spiders come in contact with the powder, the fine particles cling to their exoskeletons and dehydrate them to death, eliminating infestations at the source. Unlike synthetic pesticides, Harris Diatomaceous Earth remains effective as long as it stays dry, providing continuous protection indoors and outdoors. Use it in the home, garage, garden, basement, attic, or wherever crawling insects are a problem. Whether you're dealing with a serious infestation or want to prevent one, trust the power of nature with Harris Diatomaceous Earth Crawling Insect Killer—America’s #1 name in diatomaceous earth pest control

Review: Not for bed bugs! - Just get your beds outside to the sun it doesn't work alone you need an actual bug repellent to be acompany it
Review: Open only in secure space - Awful packaging. Sprinkler is DEEP INSIDE and it's IMPOSSIBLE to get it outside without pouring everything out. Otherwise risk spill and ton of dust around you. And zip-lock doesn't work at all.

## Questions & Answers

**Q: Will this kill yellow jackets?**
A: It will, BUT!!! it works slowly, kills them in 2-24hrs, so if you spray/dust a wasp or wasp nest it's going to be MAD and very much alive while it chases and stings you. If you need to kill a wasp in person use one of the wasp sprays, those work to knock the wasp paralyzed in less than 5 seconds.

If you want to prevent wasps from returning and nesting in the area, mix four tablespoons of diatomaceous earth in a quart of water , shake well, and use in a sprayer to coat the eaves/ceiling, and once it dries and they come in contact with it to try to settle there, they will get dusted & later die.

**Q: Will this kill Sarcoptes mites**
A: I believe it will kill them as well as its already been reducing the population of any bug that have been crawling on my floor. The best way to use the product is to spread it in the area where you see the infestation using the most. I hope that helps

**Q: Can this be used in a crawl space?**
A: Yes and works very well. Please just wear a good mask, gloves, and eye protection when doing it. Also take a shower when you are done.

**Q: anyone know what the 15% other ingredients are? is it bug poison? it says it 85% silicon dioxide and 15% other ingredients.**
A: nopoison

### ⭐⭐⭐⭐⭐ Review
*by J***H on 28 October 2025*

I bought this Harris Diatomaceous Earth to deal with some ants and other crawling bugs around the house, and it’s been working really well. The powder is super fine and not sticky at all — it spreads easily and doesn’t leave any kind of residue or mess. The little powder duster that comes in the bag is really handy. It makes it easy to apply the product in corners, along baseboards, and even outside around the foundation. The bag itself seals tightly, so there’s no worry about it spilling or getting moisture inside. The product quality feels high, and you don’t need to use a lot for it to be effective. For the size of the bag, it’s a great deal — plenty of powder for multiple applications. Pros: easy to use, clean to apply, good seal on the bag, great value Cons: none — it works just as described Overall, this is a great natural way to control insects without harsh chemicals. I’d definitely buy it again.
