diatomaceous earth: not the kind used for pool; the kind sold at nursery stores such as Nurseryland Garden Centers or Orange County Farm Supply in Orange. Your carpets should be vacuumed, cleaned and dry. Cover fish tanks and any electronic equipment that could be damaged by powder. Cover your nose and mouth with a dust mask, sold at hardware or drugstores. Keep your pets, incliding birds, out of the way until the dust has settled. Using a flour sifter, sprinkle the mixture liberally on all carpeted areas, including under furniture and in closets. Rub it in with a broom. Wait at least 24 hours and vacuum, then vacuum frequently. Do Not Use The Mixture On Your Pet. More Important-do not let children breath this.
