Planto, there are lots of ant baits on the market. Numerous ATP subscribers has praised one or the other of these. I just like the fact that Orthene rids me of the ants overnight and does so time after time. When ants get into my staghorns (they are up in the trees), these are never fire ants. They are the tiny, non-biting, "sugar-ants". Regardless, I don't want them in my house or in my greenhouses.
