Wow, I just read up on Crazy Ants ... don't know whether to be happy for you that they will crowd out the Fire Ants, or worried because of how invasive they are. Does it look like they are tampering with the plants?

I have found them now in the Crape Myrtles, Daylilies, and Roses, but I don't see any harm being done so far by them. At first I thought they were pretty much localized in one area of my back yard, now that I have been looking they appear to be well established just about everywhere . I think my first reaction was a panic attack, now I just don't know what to make of them...for now.I think the focus of the concern is mainly electrical and electronics damage caused by them, so far no sign of them in the house, I'm keeping a check on that.
