How to kill domestic fleas? - briefly
Use a veterinarian‑approved insecticide spray or fogger, wash all bedding and fabrics in hot water, and vacuum carpets and furniture thoroughly, repeating the process weekly until fleas are eliminated.
How to kill domestic fleas? - in detail
Domestic flea infestations require a systematic approach that combines environmental treatment, host management, and ongoing monitoring.
First, eliminate adult insects and their eggs from the living space. Apply a residual insecticide spray or fogger labeled for indoor use, focusing on cracks, baseboards, under furniture, and pet bedding. Choose products containing adulticides such as pyrethroids or neonicotinoids and an insect growth regulator (IGR) like methoprene or pyriproxyfen to prevent development of immature stages. Follow label directions precisely, ventilate the area, and keep pets and people out for the recommended period.
Second, treat the animals that host the parasites. Use a veterinarian‑approved topical or oral flea medication that kills adults on contact and contains an IGR to disrupt the life cycle. Options include fipronil, imidacloprid, selamectin, or spinosad formulations. Administer the product at the recommended interval—typically monthly—to maintain efficacy.
Third, address the indoor environment where eggs and larvae reside. Vacuum all carpeted floors, rugs, and upholstery daily; discard the vacuum bag or clean the canister immediately to prevent re‑infestation. Wash all removable fabrics—bedding, curtains, pet blankets—at temperatures of 60 °C (140 °F) or higher. For non‑washable items, steam‑clean or apply a flea‑killing powder such as diatomaceous earth, ensuring it remains dry to preserve its abrasive properties.
Fourth, implement preventative measures to break the cycle. Maintain a regular cleaning schedule, keep pet habitats tidy, and use year‑round flea prophylaxis on animals. Seal gaps around doors, windows, and baseboards to reduce access points for wandering insects.
Summary checklist
- Apply indoor residual spray/fogger with adulticide + IGR.
- Treat pets with veterinarian‑approved topical or oral product.
- Vacuum daily; dispose of debris promptly.
- Wash or steam‑clean all fabrics; use diatomaceous earth on dry surfaces.
- Continue monthly pet medication and routine house cleaning.
Consistent execution of these steps eradicates existing fleas, prevents maturation of new generations, and minimizes the risk of recurrence.
