How to get rid of many fleas in a house? - in detail

Eliminating a severe flea infestation requires simultaneous action on pets, the indoor environment, and the surrounding outdoor area.

First, treat every animal that spends time inside. Use a veterinarian‑approved adulticide (e.g., selamectin, imidacloprid, or fipronil) applied according to the label schedule. Administer a short‑acting adulticide (such as a spray or fogger) to kill insects already on the host, then continue with a long‑lasting preventer to stop new eggs from hatching.

Second, remove eggs, larvae, and pupae from the house. Follow these steps:

  • Wash all bedding, blankets, and removable fabrics in hot water (≥ 60 °C) and dry on high heat.
  • Vacuum carpets, rugs, upholstery, and floor seams thoroughly; discard the vacuum bag or clean the canister immediately.
  • Apply an insect growth regulator (IGR) such as methoprene or pyriproxyfen to carpets, cracks, and baseboards; these compounds prevent immature stages from developing into adults.
  • Use a flea fogger or aerosol spray labeled for indoor use, focusing on dark, undisturbed areas where pupae hide (under furniture, pet crates, closets). Follow the manufacturer’s safety instructions, vacate the premises, and ventilate before re‑entry.

Third, address outdoor sources that feed the indoor population. Trim grass, remove leaf litter, and treat shaded zones with a pet‑safe outdoor flea spray or IGR. Keep dogs and cats on a regular monthly flea preventive to stop re‑infestation from the yard.

Finally, maintain a preventive routine:

  • Repeat vacuuming and washing of pet bedding weekly for at least four weeks.
  • Reapply IGR treatments according to product recommendations (typically every 30 days).
  • Inspect pets weekly for live fleas; retreat immediately if any are detected.

Coordinating chemical control, rigorous cleaning, and ongoing pet protection eliminates the infestation and prevents recurrence.
