I have been doing a lot of work in the backyard and over the past few days, detected a strong odor of benzene or naphtha. It is nauseating to say the least. When I put the trash in the alley this morning, I noticed that my next door neighbor has placed mothballs all along the perimeter of her back and side fence next to mine - with one every 3-4 inches. It seems to me that this might be dangerous for pets, birds or even people happening by. I am not the type to confront neighbors over things that bother me, but am very concerned about it. I get that things like skunks are problematic but if you keep your yard cleaned up and don't provide them food or shelter, they generally aren't an issue. Anyone dealt with a neighbor over this or a similar issue?
