Had high hopes for this bait, per the ad on your website which labeled it as the best of all you offered. When I got it, I noticed the label was very specific as to what species of ants it affected. I would consider it minimally effective on the ants we are dealing with in Las Vegas. They seem to be curious to it, but they keep coming. Not slowed down at all. Better bait, although very expensive, is the Terro-Pro.
