Works great! Got this to get rid of aphids on our roses and ants living INSIDE our strawberry bed and to deter slugs from our hostas! I DIY'd a powder sprinkler (see pic) instead of buying one. I used a small narrow food container with a lid and spout and poked several holes in the top of the lid over the spout and I just squeeze the container over the area I'm covering (similar to how you would with a baby powder container). You could also use an empty plastic water or soda bottle and poke holes in the cap. NOTE: If using on and around plants, try to avoid sprinkling on flowers so pollinators don't get any on themselves. I had aphids living on my rose buds so I had to sprinkle the buds but now that they're dead I will be rinsing off as much product as I can to avoid harming any pollinators

Best buy for the money!

This Organic Food Grade DE is a great price!!! One of the best insect deterrents in my garden. It's also a good fertilizer type nutrient as well. Apply it dry or use it as a foliage spray. Great to start with your seedlings as well. ...and best thing is not harmful to animals or people if used properly.

Will use again! and again... and again...

My apartment is roachy and they're coming in from my neighbors apartment, so really all I can do is complain to the manager and do what I can to keep them away. Putting this stuff down makes it way easier to fight them off hands down. Not only does it kill them but it also shows me possible entry points and locations to dust when I find powder free bugs. Also resulted in a masterpiece I'll laugh at for years to come (attatched photo).
