How can fleas that have appeared in an apartment be eliminated? - in detail
Fleas found in a dwelling require rapid, coordinated action. Begin by isolating all animals, washing them with a veterinarian‑approved flea shampoo, and applying a topical or oral adulticide within 24 hours. Treat each pet according to the product’s schedule, repeating the dose after the life cycle’s pupal stage to prevent re‑infestation.
Next, eliminate all stages of the parasite from the living space. Vacuum every carpet, rug, upholstered seat, and floor crevice thoroughly; discard the vacuum bag or clean the canister immediately. Launder bedding, pet blankets, and removable covers in hot water (≥ 60 °C) and dry on high heat. Sprinkle a fine layer of diatomaceous earth on carpets and left‑unfurnished floors, leave for several hours, then vacuum.
Apply an environmental insecticide labeled for indoor flea control. Choose a product containing an adulticide (e.g., permethrin, bifenthrin) and an insect growth regulator (e.g., methoprene, pyriproxyfen). Follow label directions precisely: treat baseboards, under furniture, cracks, and any cracks in flooring. For severe infestations, consider fogging or a professional heat‑treatment service, ensuring adequate ventilation afterward.
Seal entry points that allow stray animals or rodents to bring new parasites. Repair torn screens, close gaps around doors, and store firewood away from the building. Maintain regular grooming and preventive medication for pets throughout the year to interrupt the flea life cycle before eggs are deposited.
Monitor the situation for four weeks. Continue weekly vacuuming, repeat pet treatments as recommended, and re‑apply environmental insecticide if live fleas reappear. Persistent absence of adult fleas, eggs, and larvae confirms successful eradication.
