I understand your concern. I just used it as directed. You can get the weaker version of it. Bifen IT, Bifenthrin 7.9% Insecticide. Cost just as much and you would use 3 times as much per application. So I just asked how to use it and went to work. Please let me know what your neighbor says. If there is a expert in the house I am all over it. I have had really goo luck with it so far.
I think I am going to have one of my sons jump on the roof and spray that too. It would be just my luck if they lived under the panels and after all that work they showed back up.
