Gets The Job Done!
I’ve been using Diatomaceous Earth every spring to deal with clover mites and it works great. It’s one of the most effective solutions I’ve found for keeping them under control without having to rely on harsh chemicals. Once it’s applied, it does exactly what it’s supposed to do and keeps the problem from getting out of hand. It can be a little messy during application, but that’s a small trade off for how well it works. I appreciate that it’s long-lasting and reliable year after year. If you’re dealing with clover mites or other crawling insects, this is a product that really gets the job done.

Works Great and Super Easy to Use
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.

This stuff works. Use as directed and wear a mask if using applicator.
I live in public housing and there is a huge bug problem... roaches & bedbugs. I had both for a while until someone suggested Diatomaceous earth. I put some of this all over the place at first, right on the kitchen counters where roaches crawl, all around the bed, even on the bedframe itself on the flat parts, I put it everywhere I saw a bug ; Didn't take long for the entire population of both kinds of bugs to die off. I rarely see a roach or a bedbug now, despite the neighbor's places crawling with them. I can live like a normal person while others , who refuse to even consider doing the work it takes, live in squalor. This stuff made my life so much better I keep a bag of it around to help others if they will take it. If you don't get it wet it will last a very long time. Bugs crawl through it and die quite soon after. It's safe as long as you wear a mask while applying it with the applicator. It's so good that the exterminator does not come in my apartment, he says I do a better job than his spray can do. He says I have the best apartment in the building as far as lack of bugs goes. It has no smell. It doesn't blow around unless you point a blast of air directly at it. You can make little berms of it wherever bugs crawl ; they crawl through it and then they die soon after, carrying it back to the nest where it will kill others too. GREAT PRODUCT all natural just don't breathe it in directly and even if you do it won't hurt you in small amounts just agitate your throat a little bit.

It's safe
Works well with adult roaches. Takes a little longer with baby ones. Maybe because the weight difference. I believe one they crawl on the powder it cuts them and the die in their nest area. So far I believe it's working. I feel better knowing this is safe because of my fur babies. The powder is made from ground shells.

Needs to stay dry
Works great, ants at front door, and one of my bedroom windows. My son n law sprinkled powder outside around my window and front door. Seems to me Ants don’t want to get in near it. Not sure, but they’re staying away from door and stopped coming in my window. I like that it’s not toxic, I have budgies free 24/7 I will not use it inside my room because it’s a powder. will not work if it gets wet, not an issue for me. I’ll just put more.

Great product, poor packaging
I swear by this stuff, I have lived in a few rentals that have had bug problems. They build up a tolerance for whatever the pest control is using. It's usually the kitchen, so we put this as a line down around the base boards, between the stove and cabinets as well as between the refrigerator and cabinets. Any key places you've seen the bugs to know they will travel through the powder. Keep in mind, it is very fine, I recommend gloves, eyewear, and a mask. Now, for this option, I did not like the tool included as it would get clogged every few pumps, I would have to take the attachment off and tap it out before repeating that over. It was also buried in the bag so it was covered and made a huge mess before I even got started. When I was done and tried closing the bag, the zipper would not work because the powder was compacted in the line. I tried cleaning it out but I could never get it to close, I ended up folding it over and using a big binder clip to keep it shut. Not impressed with the packaging.

My Secret Weapon Against Creepy Crawlies
As much as I love my home, I absolutely do not love uninvited insect guests. After trying various sprays and traps, I decided to go a more natural route and try Harris Diatomaceous Earth Crawling Insect Killer, and I'm so glad I did! This 8oz container is surprisingly mighty. I've used it for a range of pests – from those sneaky ants that try to invade the kitchen to the occasional spider. What I love about DE is that it's a non-toxic way to deal with insects. You just sprinkle a fine layer where you see activity (or where you suspect they're entering), and it works by dehydrating them. It's not an instant kill like a chemical spray, but it's incredibly effective over a short period. I've used it along baseboards, under sinks, and even lightly dusted pet bedding for fleas (after ensuring it's food-grade, which this is!). It's a bit dusty when applying, so a mask is a good idea, but the peace of mind knowing it's a natural solution is worth it. Plus, it's long-lasting as long as it stays dry. If you're looking for an effective, natural, and non-toxic way to combat roaches, fleas, ants, bed bugs, and other crawling insects without harsh chemicals, this Harris Diatomaceous Earth is a total game-changer. It's become my go-to for keeping my home bug-free!

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.
