What should be done if fleas have spread in the house? - in detail
If fleas have infested the residence, immediate action is required to eliminate the insects and prevent re‑infestation.
Begin by treating all animals that share the space. Apply a veterinarian‑approved adulticide to pets, following the product’s dosage schedule. Wash pet bedding, collars, and any fabric that contacts the animals in hot water (≥ 60 °C) and dry on high heat.
Next, address the indoor environment. Vacuum every carpet, rug, and upholstered piece thoroughly; discard the vacuum bag or clean the canister immediately after use. Steam‑clean carpets and flooring where possible, as high temperature kills all life stages. After vacuuming, spray a residual insecticide labeled for indoor flea control, covering baseboards, cracks, and under furniture. Allow the product to dry before re‑entering the rooms.
Treat the exterior perimeter of the home. Apply a yard‑safe flea spray or granules around the foundation, focusing on shaded areas, pet shelters, and mulch. Trim vegetation that contacts the building to reduce humidity and create a less favorable habitat.
Implement a monitoring routine. Place flea traps (e.g., sticky cards) in high‑traffic zones for two weeks, inspecting daily and replacing as needed. Continue weekly vacuuming and maintain pet treatments for at least one month to break the flea life cycle.
Finally, prevent future outbreaks. Keep pets on a consistent preventative regimen prescribed by a veterinarian. Maintain low indoor humidity, regular cleaning, and prompt removal of stray animals that may introduce new infestations.
