THIS STUFF REALLY WORKS!

this is not advertised as a cockroach killer but has worked WONDERS! Ive tried everything and i mean everything! even paid a exterminator over $100 and it just made the problem worse! it was disgusting honestly, the roaches took over my house! so my mother in law told me about this, i used it and will never need to use anything ever again! not only did it kill the roaches including their nest but it keeps them away too! everyone ive told about this used it and had nothing but praises about it! the only thing is that the smell isnt that pleasant when you first put the powder down, and you have to keep children %26 pets away till it settles and dont let them have access to it! but once it settles(about a hour after applying) its no problem at all! it rids ants, roaches and more! bit it actually works!! i do and have recommend this product and it hasnt failed not once!

Works every time!!

This is all you need for ants. It doesn't take alot either. As I got near the bottom of the jug I only sprinkled a teaspoon on a big mound. It killed them all. I keep it up high in the utility cabinet inside to keep the ingredients active and it has lasted years!! Be sure you keep all insect killers inside if you live in a hot climate. Heat of 80 degrees or higher starts inactivating the ingredients.

This product stinks to high heaven. You won't believe how bad it smells, especially if it's over applied. However, it works exactly as advertised: just a light dusting of it on the surface of an ant mound kills an entire colony of ants in minutes. I've almost erased the fire ant presence from my yard completely! Perfect for getting the fire ants out of your yard. Don't use it in the house.
