put this out for roaches as well. it get rid of them including the ones you been trying to get rid of for years. I've been living in this apartment complex for 7 years and have not had any roaches. I just started seeing a couple last week and I hurried up in order some more.

WORKS LIKE MAGIC...

If you have been using Spectricide...immediately throw it away! This fire ant killer really works. I've used it on 6 mounds within the past two weeks and no fire ants have rebuilt duing that time. With other brands, they just seem to move a couple of feet and rebuild. Several of these ant nests are dormant within a couple of hours.

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.
