How to kill cat fleas in the house? - in detail
Eliminate indoor cat fleas by combining chemical, mechanical, and environmental strategies.
First, treat the pet. Apply a veterinarian‑approved topical adulticide (e.g., fipronil, imidacloprid) or oral medication (e.g., nitenpyram, spinosad). Follow the label dosage exactly, repeat according to the product schedule, and monitor for adverse reactions.
Second, clean the living area. Perform these steps:
- Vacuum all carpeted surfaces, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately after use.
- Wash bedding, blankets, and any removable fabric at ≥ 60 °C (140 °F) or use a dryer on high heat for at least 30 minutes.
- Steam‑clean hard floors and carpets, as temperatures above 50 °C (122 °F) kill all life stages.
- Apply an EPA‑registered household flea spray or fogger to cracks, baseboards, and under furniture; ensure the product covers eggs, larvae, and pupae.
Third, address hidden habitats. Sprinkle diatomaceous earth or a silica‑based powder in crevices, pet sleeping spots, and under furniture. Reapply after cleaning or when the powder becomes damp.
Fourth, maintain preventive measures. Use a monthly flea collar or spot‑on treatment on the cat, keep the home humidity below 50 % (flea larvae require higher moisture), and continue regular vacuuming for at least four weeks to break the life cycle.
Finally, verify effectiveness. Inspect the cat daily for live fleas, use a fine‑toothed flea comb, and repeat environmental treatments if any fleas reappear within two weeks. Persistence of these actions for a full month eliminates the infestation and prevents recurrence.
