Google search reveals high praise for fly-bait, generic: methomyl, brand: Golden Malrin. Poultry farmers swear by it. Mix a soft-drink (not diet) with fly bait crystals in an aluminum pie plan. Raccoons die within minutes, sometimes flopping into the plate. It *will* kill anything that samples it, buy there are mixed opinions as to whether cats or dogs would sample it. To be safe, I'll keep the damn dumb cat inside or else locked-in on the screened-in deck.
