Fleas can be killed and controlled using a variety of methods and products targeting different stages of their life cycle: Chemical Insecticides and Treatments:
- Household insecticides with active ingredients such as malathion, methoprene, propoxur, and pyrethrins are effective for killing fleas in the home environment.
- Topical prescription medications (e.g., Frontline, Revolution) applied to pets kill adult fleas and prevent new eggs from hatching
- Oral prescription flea medications like nitenpyram (Capstar) kill adult fleas quickly after they bite the pet
- Flea sprays for pets and homes can kill fleas on contact but must be pet-safe and used according to instructions
- Flea sprays and insect growth regulators (IGRs) containing pyrethroids like bifenthrin are effective for yard treatment
Natural and Non-Chemical Methods:
- Food-grade diatomaceous earth can be sprinkled on carpets, furniture, and pet bedding; it kills fleas by dehydrating them and is safe for humans and pets
- Regular washing of pet bedding and household fabrics in hot water (above 130°F) and drying on high heat kills fleas at all life stages
- Bathing pets with flea shampoos containing pyrethrin or mild soap can kill adult fleas on the animal
- Vacuuming carpets and furniture frequently removes fleas, eggs, larvae, and pupae from the home environment
- In yards, spreading cedar chips repels fleas, and nematodes (microscopic worms) can be introduced to eat flea larvae naturally
- Maintaining a clean yard by mowing, removing debris, and avoiding overwatering reduces flea habitats
Summary:
To effectively kill fleas, a combination approach is recommended:
- Treat pets with appropriate topical or oral medications.
- Clean and treat the home environment with insecticides or diatomaceous earth.
- Wash pet bedding and vacuum regularly.
- Treat the yard with insecticides or natural remedies like cedar chips and nematodes.
- Maintain yard cleanliness and limit pet exposure until fleas are controlled.
This multi-pronged strategy addresses fleas at all life stages and locations, ensuring thorough eradication
