Not for bed bugs!

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.

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.

I am gonna give my honest review on this product.. I dont think this product work on roaches. It says on the instruction it kills them within 24 hours of contact but i have apply this for at list 3 to 4 days and no result.Yes when you put them around your house, it calls the roaches around and you see them but as of killing them, I didn't see anything like that because I keep seeing the roaches approach the product but never die. Maybe it product might be able to kill lil insert in the garden but not roaches.Plus it make a lot of mess around your house. Look for better options.
