How to treat bedding for fleas? - briefly
Wash all bedding in water at least 130 °F (54 °C) and dry on the highest heat setting to eliminate every life stage of fleas. Then vacuum the mattress and surrounding area thoroughly and apply a pet‑safe flea spray or diatomaceous earth to prevent re‑infestation.
How to treat bedding for fleas? - in detail
Treating flea‑infested bedding requires a multi‑step approach that eliminates all life stages of the parasite and prevents re‑infestation.
First, remove all removable items such as pillowcases, blankets, and mattress covers. Wash them in water at least 130 °F (54 °C) for 30 minutes; this temperature kills adult fleas, larvae, and eggs. After washing, tumble‑dry on the highest heat setting for a minimum of 20 minutes to ensure complete eradication.
Second, address the mattress and box spring. Vacuum the entire surface thoroughly, paying special attention to seams, crevices, and the underside of the mattress. Dispose of the vacuum bag or empty the canister into a sealed plastic bag and discard it outdoors. Follow vacuuming with a steam‑cleaning cycle; steam at temperatures above 120 °F (49 °C) penetrates fabric fibers and destroys hidden stages.
Third, apply a residual insecticide formulated for indoor use on fabrics. Choose a product containing an adulticide such as permethrin or a growth regulator like methoprene. Lightly mist the mattress, bed frame, and surrounding area, adhering to the manufacturer’s safety instructions. Allow the treated surfaces to dry completely before re‑making the bed.
Fourth, consider a non‑chemical option: sprinkle a thin layer of food‑grade diatomaceous earth over the mattress and bedding, then leave it for 24 hours before vacuuming. The abrasive particles desiccate fleas without affecting humans or pets when used as directed.
Finally, implement preventive measures. Encase the mattress and box spring in flea‑proof covers that are zip‑sealed, reducing future exposure. Maintain a regular cleaning schedule: weekly vacuuming, monthly laundering of all bedding at high temperature, and periodic application of a flea‑preventive spray in the sleeping area.
Following these procedures systematically eliminates existing flea populations in bedding and creates an environment hostile to new infestations.
