don't buy harmful flea powders or drops that only last up to 2 weeks any more! if you dog or cat is infested with fleas pour jhonsons baby powder on their coat and comb through fur, really good. you may need to repeat in some cases. start from head then work you way down to tail, DO NOT POUR ON DOGS FACE !!!!!!. if you start from the backside first they will rush to the head making it more difficult to kill them. for carpet, first start to pour on the outside rim of the carpet traping the fleas then quickly start covering the rest of the carpet. let set for about 10 minutes then vacumme. TIP: when putting it on the carpet pour closely to the carpet so it dosent poof in the air. ANY QUESTIONS OR CONCERNS? JUST ASK. for beds do the same as the carpet then use the attatchment shown below on your vacume to remove the powder.
