It does work for us, that is all I know.If you don't think it WILL work or don't want to try it, that is up to you! why don't you Google lavender and see what you can find out. all I know is we do live in a flea area and since using this, we don't have them anymore. No one is harmed or poisoned, no one has a bad reaction and no one gets sick. THAT is good enough for me!
Johnson & Johnson Lavender Baby powder, we will NEVER be with out it in our house!
