I have done a fair bit of work in the safety testing industry. "EPA approved" may mean a product is safe, or it may mean it was grandfathered before testing was required, or it may mean that they didn't think testing was necessary; and in any case, it's not fool-proof. Many safety issues are discovered only after years of use. DDT is a good example of something that was thought to be safe, but then obviously was not. I think Sam's right to wonder how it kills ONLY mosquitoes and nothing else is affected. We only use pesticides in cases where they are absolutely necessary.
