Flea Products: Combatting Fleas on Your Dog or Cat
by Trissauna Larson, D.V.M.
Sprays, Foams, Spot-Ons, Combs
Most pet owners in the United States will have to deal with fleas at some point. When warmer weather approaches, flea populations boom. Fleas can leave your pet with annoying bites, allergic skin irritation, tapeworms or anemia. Many products are available through stores and veterinary clinics to help a pet owner win the war on fleas. Holistic remedies are also available.
Combs
Great for puppies and kittens who are too young for chemicals.
Collars
Made with insecticides to kill adult fleas or insect growth regulators (IGR) which prevent flea eggs from hatching. Used alone, it's often not enough to keep fleas under control.
Powders
Most have insecticides that kill adult fleas, but can be messy to use.
Sprays and Foams
Sprays and foams contain insecticides, and may also have an IGR. These work well, but frequent applications are usually necessary.
Shampoos and Dips
Most have action against adult fleas. Shampoos generally offer no flea-killing ability after 24 hours. Dips may kill fleas for a few days, but can contain potent chemicals. For these reasons, I recommend using a mild shampoo and having dips done by veterinary clinics or groomers only.
Over-The-Counter (OTC) Spot-Ons
Dogs: Bio Spot, Control, Power Spot are examples of liquid insecticides which are squeezed onto the skin of pets to kill adult fleas for up to one month. Some products also have an IGR.
Cats: OTC spot-on products for cats generally have only an IGR, so won't kill adult fleas. Spot-on products for dogs may contain insecticides that are toxic or fatal to cats. Read labels carefully!
Veterinary-only Products
Program
Program is given once a month, orally, or as an injection for cats every six months. It prevents flea eggs from developing, but does nothing to kill existing adult fleas.
Veterinary Spot-Ons
Advantage, used once monthly, and Frontline, used every 1-3 months, kill adult fleas without using traditional insecticides. Frontline is my favorite because of the long action and the ability to kill ticks. The main disadvantage is cost, which can be up to five times higher than OTC products. I feel the safety and effectiveness of these products is worth it.
Revolution
Brand new to the market, Revolution is a prescription spot-on product for dogs and cats. It kills adult fleas and their eggs, in addition to mites and worms. It is also a heartworm preventative. Flea control must be tailored to each pet and owner. Pets, home, and yard must all be part of the treatment plan. Try different products to find the ones that work best for you and your pet. Most importantly, read all label directions carefully and consult your veterinarian for recommendations.
