How to get rid of fleas in the house

Flea infestations have to be hit on three fronts at once — pet, home, and yard — or they bounce back. Their life cycle takes 3–4 weeks, so treatment continues that long even when bites stop. Most cases clear in 4–8 weeks if you stay consistent.

Difficulty: Medium Time: 1 hr initial setup, 4–8 wks protocol Cost: $50–150

Steps

  1. 1

    Treat every pet on the same day

    Give a Capstar pill (immediate adult kill) AND apply monthly topical preventative. Treat every pet in the house even if only one is scratching.

  2. 2

    Wash all pet bedding hot

    Strip pet beds, blankets pets sleep on, throw rugs in pet areas. Wash on hot, dry on HIGH for 60 minutes. Repeat weekly for 6 weeks.

  3. 3

    Vacuum every surface daily

    Carpet, upholstery, between couch cushions, under furniture. Vibration triggers pupae to emerge — vacuuming captures them. Discard the vacuum bag in outdoor trash immediately.

  4. 4

    Spray indoor surfaces with Precor

    Apply Precor 2000 to carpets, rugs, upholstery, baseboards, pet sleeping areas. Let dry fully before pets return to the area. Reapply at 4 weeks.

  5. 5

    Treat the yard

    Apply Wondercide via hose-end sprayer to the lawn perimeter, under decks, around the dog run, and shady spots where pets rest. Reapply at 4 weeks.

  6. 6

    Stay consistent for the full life cycle

    Flea eggs and pupae hatch over 3–4 weeks. Bites may stop in 7–14 days, but if you stop treating, the next wave hatches. Continue all three fronts (pet, home, yard) for at least 8 weeks total.
