What should you do if dampness in the house leads to a flea infestation? - briefly
Address the moisture problem by repairing leaks, increasing ventilation, and using a dehumidifier to dry affected areas. Then eradicate the fleas with a comprehensive approach: vacuum thoroughly, wash all linens in hot water, and apply a suitable insecticide or professional pest‑control service.
What should you do if dampness in the house leads to a flea infestation? - in detail
Moist environments create ideal breeding grounds for fleas; eliminating humidity is the first priority. Locate the source of excess moisture—leaky pipes, roof cracks, condensation on walls, or damp basements. Repair plumbing defects, seal roof penetrations, and improve ventilation. Use a dehumidifier or install exhaust fans to lower indoor relative humidity below 50 %.
After the area is dry, remove all flea stages from the home. Wash bedding, curtains, and removable upholstery in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, rugs, and upholstered furniture thoroughly; discard the vacuum bag or clean the canister immediately. Apply an insect growth regulator (IGR) spray or powder to cracks, baseboards, and pet bedding, following label directions. Treat pets with veterinarian‑approved flea preventatives to stop adult fleas from returning.
Sanitize the premises to prevent re‑infestation. Steam‑clean hard floors and tile grout. Seal gaps around doors, windows, and utility penetrations to block flea migration. Maintain a consistent cleaning schedule: vacuum weekly, launder pet linens regularly, and monitor humidity levels with a hygrometer.
If infestation persists after these measures, enlist a licensed pest‑control professional. Request an integrated pest‑management plan that combines chemical treatments, environmental control, and ongoing monitoring. Document all actions taken and retain receipts for potential insurance claims or landlord negotiations.
