You can kill fleas that are living on bed linens, but they will come right back if you do not control the flea population in the rest of your house. You must treat carpets, yards and pets for fleas as well. The Northwest Coalition for Alternatives to Pesticides (NCAP) recommends natural pest control methods to avoid exposure to toxic chemicals. You can use natural, pet-safe pesticides in yards and around your house. You can treat pets for fleas with either a natural, pet-safe pesticide shampoo and a flea comb or another method recommended by your veterinarian.
To kill fleas, wash bed linens in a washing machine using regular washing powder.
Dry bed linens in a clothes dryer set at the highest temperature allowed according to the bed linen care label.
Rewash bed linens every three days to kill any newly hatched fleas. Do this until the flea population in the household is gone.
Spray bed linens lightly with a natural pesticide to kill and repel future fleas. D-limonene and linalool are natural pesticides that are derived from citrus extracts. The organisation "Beyond Pesticides" states in the "Journal of Pesticide Reform" that d-limonene and linalool are effective for controlling flea populations.
Always read the label of flea control products to learn if they are safe to use around your pets. Cats especially are sensitive to many flea control products.
