Remove all the bedding and linens in your home. Put sheets, pillowcases, duvets, bedspreads, dust ruffles, place mats, shams, tablecloths and curtains in a washing machine and wash them in hot water using the appropriate amount of detergent.
Put on protective eyewear and a mask that covers your nose and mouth. Take a large canister of diatomaceous earth and sprinkle it all over your carpet, upholstery and your pet's bed. Diatomaceous earth causes fleas to die organically, without exposing you or members of your household to noxious chemicals. Vacuum it up after eight days.
Add a quarter cup of all-purpose floor cleaner to a gallon of hot water in a bucket. Mop down your floors. Wipe down all your counters and surfaces with a sponge dipped in a gallon of hot water mixed with a quarter cup of liquid detergent.
Bathe your pet with flea shampoo. Comb through your pet's fur with a flea comb, removing as many flea eggs as you can and disposing of them immediately. Rub a store-bought flea powder into your animal's fur.
