I'm impressed. We're having HORRIBLE flea wars and Tallulah developed a reaction to Advantix and Advantage (and Frontline doesn't even work), so it's a battle. She has a reaction to flea soaps too, and they make ME itch when I bathe the dogs so they can't be feeling that great on the dogs. She's okay with Neem based stuff, and the Neem capsules seem to be helping some. I just gave Kharma a bath with Dr. Bonner's Castille hemp and tea tree soap. THE FLEAS DIED ON CONTACT, and I'm not itching. Now to see how Tallulah tolerates it . . .
