How to treat laundry for fleas? - briefly
Wash infested fabrics in the hottest water safe for the material, using a strong detergent and adding a flea‑killing additive such as an approved insecticidal spray or a cup of white vinegar. Dry them on the highest heat setting for at least 30 minutes to ensure any remaining parasites are eliminated.
How to treat laundry for fleas? - in detail
Flea‑infested fabrics require a systematic approach to eliminate all life stages of the parasite. Begin by separating clothing, bedding, and washable items from non‑washable materials. For each wash‑able piece, inspect for visible fleas or eggs and remove any debris with a lint roller or fine brush before laundering.
- Water temperature – Use the hottest setting the fabric can tolerate, ideally 130 °F (54 °C) or higher. Heat denatures flea proteins and kills eggs and larvae.
- Detergent – Apply a full‑strength detergent; enzymatic formulas enhance breakdown of organic matter that may shield insects.
- Additives – For white or color‑fast items, add a cup of non‑chlorine bleach or a half‑cup of white vinegar to the wash cycle. Both agents lower pH, creating an environment hostile to fleas.
- Cycle length – Select an extended wash (30 minutes or more) to ensure thorough exposure.
- Rinse – Perform an extra rinse to remove residual chemicals that could attract surviving parasites.
- Drying – Transfer items immediately to a dryer set on high heat (≥ 140 °F / 60 °C) for at least 30 minutes. Heat penetrates fibers and guarantees destruction of any remaining stages.
For items that cannot endure high temperatures, use a cold‑water wash followed by a specialized flea‑killing laundry additive, such as a commercial insecticide formulated for fabrics. After washing, seal the garments in airtight bags for 48 hours; fleas cannot survive without a host beyond this period.
Finally, clean the washing machine and dryer interior. Run an empty hot‑water cycle with bleach, then wipe drum surfaces with a disinfectant. Vacuum surrounding areas and dispose of vacuum bags or clean the canister to prevent re‑infestation. Following these steps consistently eradicates fleas from laundry and reduces the risk of re‑introduction into the home.
