They are here in KY also. I used a new chemical this year and have had very few so far this summer. I think the key is putting the stuff on in the early spring to catch them when they are very small or just hatching. Even squashing them does not work when they get bigger, have to behead them. I do not think that adding anything after they are already down in the fans is useful. Someone correct me if I am wrong. Destructive little buggers....I am vigilant daily searching for signs. My husband thinks I am praying over them...Ha.
