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!

If u have roaches this stuff is all u'll ever need

This is the stuff exterminators hate for you to find out about! Just buy the Applicator tool that sprays a light mist of this powder and won't see a roach in sight after a week %26 1/2 then they'll be gone. We had a problem with tree roaches getting in the house after we used this stuff we've seen nothing.

Good stuff

Moved here 8 years ago and OMG the fire ants are just horrible in Florida! This stuff works great but like all other powders and pellets it doesn't reach the queen. But it does kill off a lot of them. It's the best product I've found so far and a tablespoon on a mound will handle it so it lasts quite a while.
