Recommendations for Your Clients


The best way for pet owners to avoid flea and tick problems is to use oral medications and clean their homes regularly to thoroughly remove flea larvae and eggs. We encourage veterinarians and other animal care professionals to share these recommendations with their clients1,2,3:


1. Speak to your vet about oral medications to protect pets against fleas, ticks, and other parasites

  • Work with your veterinarian to select appropriate oral medications to protect your pets. Some chewable oral medications protect against ticks and other parasites like hookworms, roundworms, and/or heartworms, in addition to fleas.
  • If additional topical flea control is needed, consider using flea shampoos or dips that contain pyrethrinsPyrethrins, not to be confused with pyrethroids, are much less toxic than other flea shampoo chemicals and they decompose quickly.

2. Avoid products that contain toxic chemicals

  • Avoid using external or topical flea and tick treatments to avoid exposing your pets and family to toxic chemicals. Topical collars and spot products can transport pesticides onto hands, clothing, and other indoor surfaces around your home.
  • Avoid house sprays, foggers and house “bombs.” These items have limited effectiveness and lingering residue transfers to objects, pets, and occupants, even when used as directed.
  • Avoid treatments containing chemicals that are highly toxic and persist in the environment, including fipronil, indoxacarb, imidacloprid, bifenthrin, deltamethrin, and permethrin

3. Clean your home regularly and thoroughly to prevent flea problems before they start

  • Vacuum carpets, floors, furniture, and inside cracks and Reduce clutter around your home to improve the effectiveness of vacuuming and dusting. If you are able, consider replacing carpets with hardwood floors.
  • Wash pet bedding and other fabrics that pets touch regularly, including human bedding.
  • Use flea combs. Dip the comb frequently into soapy water to capture and drown fleas.
  • Use flea traps to help determine the size and location of the infestation. You can make your own flea trap by putting soapy water in a shallow baking tray and leaving it in a room overnight with a small lamp aimed at it. The fleas will be attracted to the light, and results will be visible in the morning.

4. Dispose of unused pet medication safely

  • Never flush old, unused pet medication! Instead, use the Earth911 Search Engine to find a safe disposal location near you.
