I'm no help either. I hope you find something soon though. We are having a problem with ants also. They are in our tree out in the backyard. A huge nest of ants. Great big black ones! Someone called them carpentar ants. A neighbor behind us had started to see a few ants in his house and called an exterminater and it turns out that they are coming from our tree. We had no clue and this neighbor didn't even tell us! We found out from another neighbor. Who the first neighbor had told and the second neighbor actually saw him spraying our tree a few times and was so worried about the dogs that he came over and got us. Thank God!! Alden talked to the first neighbor and was very nice and told him he would take care of the problem and to please not spray the tree anymore. We still think he came in the yard and sprayed one more time after Alden talked to him. He told Alden he didn't think the stuff would hurt the dogs because he says it is ok after it dries for a couple of hours. I don't know when he sprayed though and he doesn't know when I am going to put the dogs out. ARGH!!!! Anyway we finally got him to leave it alone and I think Alden is even going to offer to pay for his exterminator, because we do feel bad about it. Alden is taking care of the tree and has built a small fence around it for now so the dogs can't get near it. We think the ants are dead now, but they pretty much have the tree weak and hollowed out in a lot of places so it looks like we might have to chop it down. It bloomed out so pretty this spring too and it breaks my heart it is one of my favorites. We don't know why the backyard neighbor acted so weird about it. He is always nice and we have never had a problem with him. He is getting older maybe that has something to do with it. All I can say is Thank God for Mr. Anderson! He is the one that let us know and the best neighbor in the whole wide world!!!!!
