Has anyone found an earth friendly way to rid the yard of fire ants? Last year I tried diatomaceous earth. They didn't seem to like it, so they would move over a couple feet and build again. Not really the effect I was hoping for.
From Oliver: There is an Organic ant killer that has worked well for me. It is made by Greenlight and the active ingredient is spinosad. I seems to have low toxicity to everything but insects that eat it. You can get it here.
Thanks, Oliver! These ants are so aggressive. Spinosad: "The active ingredient is derived from a naturally occurring soil dwelling bacterium called Saccharopolyspora spinosa, a rare actinomycete reportedly collected from soil in an abandoned rum distillery on a Caribbean Island in 1982 by a scientist on vacation" What a history! http://en.wikipedia.org/wiki/Spinosad
