What to do when fleas appear in the house? - briefly

What to do when fleas appear in the house? - in detail

Fleas infestations require immediate, systematic action to protect humans and pets and to prevent recurrence.

Begin with inspection. Locate adult fleas, larvae, and eggs on pets, bedding, carpets, and cracks in flooring. Use a fine‑toothed comb on animals, then examine the comb for trapped insects.

Treat the animals first. Administer a veterinarian‑approved adulticide (topical spot‑on, oral tablet, or collar) that kills fleas on contact and disrupts the life cycle. Follow the product’s dosage schedule precisely; repeat treatment after seven days to eliminate emerging adults.

Next, address the environment.

  • Wash all pet bedding, blankets, and removable furniture covers in hot water (minimum 130 °F) and dry on high heat.
  • Vacuum every carpet, rug, and upholstered surface thoroughly; discard the vacuum bag or clean the canister immediately to prevent re‑infestation.
  • Apply a residual insecticide spray or fogger labeled for indoor flea control, focusing on baseboards, under furniture, and cracks. Follow label instructions for ventilation and dwell time.
  • Sprinkle a fine layer of diatomaceous earth on carpets and pet areas; leave for 24–48 hours before vacuuming.

Eliminate breeding sites. Reduce humidity below 50 % and keep indoor temperatures moderate, as fleas thrive in warm, moist conditions. Repair any floorboard gaps or wall cracks where eggs could accumulate.

Monitor progress. Use sticky flea traps placed near pet sleeping spots for two weeks; a decline in captured insects indicates effective control. Continue regular grooming of pets and weekly vacuuming for at least one month.

If the infestation persists after these measures, consult a pest‑management professional for targeted treatment and possible prescription‑strength products.
