What should be done if fleas appear in the house due to dampness? - briefly
Eliminate the moisture source by repairing leaks and using a dehumidifier, then vacuum carpets, wash bedding at high temperature, and apply a flea‑specific insecticide or fogger to all affected areas. Repeat the treatment after a week to destroy any newly emerged fleas.
What should be done if fleas appear in the house due to dampness? - in detail
Fleas thrive where moisture creates a hospitable environment for eggs and larvae. Immediate action must focus on eliminating the damp conditions and eradicating the insects.
First, locate the source of excess humidity. Check for leaking pipes, roof defects, condensation on walls, or inadequate ventilation in basements and bathrooms. Repair all leaks, seal cracks, and install or improve exhaust fans. Use a dehumidifier to lower indoor relative humidity to below 50 %.
Second, dry all affected surfaces thoroughly. Move furniture away from walls, lift carpets, and expose flooring to air circulation. Wash fabrics—bedding, curtains, pet blankets—at the highest temperature the material allows. Vacuum carpets, upholstery, and crevices repeatedly; empty the canister into a sealed bag and discard it outside the home.
Third, apply a flea control regimen. Options include:
- Insect growth regulator (IGR) spray applied to cracks, baseboards, and under furniture; it prevents immature stages from developing.
- Adulticide fogger for rapid knock‑down of visible fleas; follow manufacturer safety instructions.
- Spot‑on treatments for pets, ensuring the product is veterinary‑approved.
After treatment, repeat vacuuming and washing for at least two weeks to capture any newly emerged insects. Maintain low humidity, fix water intrusions promptly, and keep indoor spaces clean to deter future infestations.
