How to get rid of fleas caused by dampness? - briefly
First, eliminate moisture by repairing leaks, increasing ventilation, and using a dehumidifier. Then, clean all fabrics, vacuum thoroughly, and apply a suitable flea insecticide, repeating treatment until no fleas remain.
How to get rid of fleas caused by dampness? - in detail
Fleas proliferate when humidity creates a favorable micro‑climate for their eggs and larvae. Reducing moisture, removing the insects, and preventing re‑infestation are essential steps.
First, measure indoor humidity. Aim for a relative humidity below 50 % by using a hygrometer. If levels exceed this threshold, install a dehumidifier or improve ventilation with exhaust fans and open windows. Repair any leaks in roofs, walls, or plumbing promptly, as standing water supplies a breeding ground.
Second, treat the environment. Wash all bedding, blankets, and removable fabrics in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately. Apply a residual insecticide approved for indoor use, focusing on cracks, baseboards, and pet sleeping areas. Follow product instructions regarding concentration and safety precautions.
Third, address the animal host. Bathe pets with a flea‑specific shampoo, then apply a veterinarian‑recommended topical or oral medication that disrupts the flea life cycle. Repeat treatment according to the product schedule to cover emerging larvae.
Fourth, maintain long‑term control:
- Keep indoor humidity consistently under 50 %.
- Use a low‑dose insect growth regulator (IGR) spray quarterly in hidden areas.
- Perform weekly vacuuming, emptying the container after each session.
- Inspect pets weekly for signs of fleas and treat promptly.
Finally, monitor progress. After two weeks, re‑inspect bedding, floor coverings, and pets. If any fleas are observed, repeat the cleaning and treatment cycle. Sustained humidity management combined with thorough sanitation and targeted pet care eliminates the infestation and prevents recurrence.
