What to do if there are cat fleas in the house? - in detail
If fleas have been found in a home with a cat, immediate action is required to prevent a rapid increase in the infestation and to protect both the pet and the occupants.
First, treat the cat. Use a veterinarian‑approved flea medication such as a topical spot‑on product, an oral tablet, or a flea collar. Follow the dosage instructions precisely and repeat the treatment according to the product’s schedule, typically every 30 days, to break the life cycle.
Second, clean the environment. Wash all bedding, blankets, and removable fabrics in hot water (≥ 130 °F) and dry on high heat. Vacuum carpets, rugs, upholstered furniture, and cracks in flooring thoroughly; discard the vacuum bag or empty the canister into a sealed bag immediately after use. Apply a residual insecticide spray or a flea fogger that is labeled safe for indoor use and specifically targets adult fleas and developing larvae. Follow label directions for ventilation and re‑entry times.
Third, address hidden stages of the flea. Sprinkle a fine layer of diatomaceous earth or a flea growth inhibitor (IGR) on carpet fibers, under furniture, and in pet sleeping areas. Leave the product for at least 24 hours before vacuuming again to remove larvae and pupae.
Fourth, monitor progress. Place flea traps—small dishes of soapy water with a light source—near the cat’s favorite spots. Check traps daily for several weeks; the presence of trapped insects indicates ongoing activity and may require additional treatment.
Finally, maintain preventive measures. Continue monthly veterinary flea control on the cat, keep bedding clean, and perform regular vacuuming. Periodic application of an IGR in the house will suppress any new hatches before they reach adulthood.
By treating the animal, sanitizing the living space, targeting immature stages, and sustaining preventive protocols, a flea infestation can be eliminated and prevented from returning.
