How to disinfect items of fleas? - briefly

Wash fabrics in water at 60 °C (140 °F) or higher and dry them on high heat or steam to eradicate all flea life stages. For non‑washable items, apply a permethrin‑based flea spray or expose them to hot‑air drying for at least 30 minutes.

How to disinfect items of fleas? - in detail

Fleas survive on fabrics, carpets, and other household items for weeks, so thorough decontamination is necessary after an infestation. The following procedures eliminate all life stages without damaging most materials.

1. High‑temperature laundering

   • Machine‑wash clothing, bedding, and washable pet accessories at a minimum of 60 °C (140 °F).
   • Use a full‑cycle rinse to ensure detergent and heat reach every fiber.
   • Transfer items to a dryer set on high heat for at least 30 minutes; the combined heat kills eggs, larvae, pupae, and adults.

2. Steam treatment

   • Apply a steam cleaner (minimum 100 °C/212 °F) to upholstery, curtains, and carpeted areas that cannot be laundered.
   • Move the nozzle slowly to allow steam penetration into seams and padding.
   • Repeat after 48 hours, when newly emerged adults become vulnerable to heat.

3. Freezing

   • Seal non‑washable items (e.g., stuffed toys, small rugs) in airtight plastic bags.
   • Place bags in a freezer set to –20 °C (–4 °F) for at least 72 hours.
   • Thaw at room temperature, then vacuum or wash if possible.

4. Chemical insecticides

   • Choose products labeled for indoor flea control, containing active ingredients such as permethrin, pyrethrins, or spinosad.
   • Apply following manufacturer directions, ensuring adequate ventilation.
   • Focus on cracks, crevices, and the undersides of furniture where fleas hide.

5. Diatomaceous earth

   • Sprinkle food‑grade diatomaceous earth on carpets, pet bedding, and floor junctions.
   • Leave for 24–48 hours, then vacuum thoroughly. The fine particles desiccate the insects.

6. Vacuuming

   • Use a vacuum equipped with a HEPA filter to remove adult fleas and fallen debris.
   • Vacuum all floors, upholstery, and pet sleeping areas daily for two weeks.
   • Empty the canister or bag into a sealed plastic bag and discard outdoors.

7. Isolation and disposal

   • Items that cannot be cleaned or treated should be sealed in heavy‑duty trash bags and removed from the home.
   • Dispose of bags promptly to prevent re‑infestation.

Combining heat, moisture, and chemical measures provides the most reliable eradication. After completing the above steps, monitor the environment for at least three weeks; any residual activity indicates a need for repeated treatment.
