A Quick Guide to Treating Fleas on Your Pet

Treating Fleas on Your Pets

In our first Flea Week blog, “Getting Rid of Fleas: A Comprehensive Guide,” we learned that the fight against fleas is a fierce battle and it must be fought on many fronts. First and foremost, you must treat your pets to protect them against fleas and ticks. In this post, we’ll explain how to get rid of fleas fast using several proven methods and strategies.

Itchy Dog - Treating Fleas on Your PetYou are not the only one that loves your pet: Fleas do too! With so many types of flea treatments and prevention on the market, how do you choose the right one? The product that is best for treating fleas on your pet may depend on your lifestyle, where you live, and even the age of your pet.

Permethrin vs. Pyrethrum: What’s the Difference?

Most flea and tick shampoos contain either permethrin or pyrethrin, so what’s the difference?

On the surface, these two insecticides are quite similar. They both kill unwanted insects and mosquitoes. They may sound similar and share certain qualities, but they are different in chemical composition and origin.

Permethrin is a synthetic, man-made chemical. Pyrethrum is all- natural and derived from the chrysanthemum plant. Pet owners need to be aware that products with pyrethrins are generally safe for dogs and cats. Permethrin-based insecticides must NOT be used on cats.

Shampoos and Dips:

Flea and tick shampoos are a great way to “start” the season, especially if you’re planning on following up with either a collar, a topical, or an oral treatment. The Gold Medal Flea and Tick Shampoo and Bio-Groom Flea and Tick Shampoo both have the active ingredient pyrethrin, making them safe for dogs and cats. Sentry Flea and Tick Shampoo contains Permethrins so you will not want to use it on cats. Vets Best Anti-Flea Spray Shampoo that is made with peppermint Oil and clove oils for a more natural approach to flea control.

Flea dips, such as Adams Plus Pyrethrin Dip, have aloe vera extract, lanolin, and sunscreen, while Martin’s FLEE Flea, Tick, and Mange Dip controls fleas for up to 28 days.

Sprays, Wipes, and Spot-Ons

Topical flea treatments can include drops or spot-ons, sprays, and wipes. Apply spot-ons by parting your dog’s hair and applying the liquid directly onto the skin. The product must be applied to the skin and not the hair to be effective. For best results, you can apply to several spots along your pet’s back (always follow label directions). If you have a very agile, flexible cat, you may want to apply the topical at the base of the skull rather than along the back. Do not rub the product in: it will be absorbed into the skin.

Advantage II has the active ingredient Imidacloprid with the IGR (insect growth regulator) being Pyriproxyfen. Frontline Plus has the active ingredient Fipronil and (S)-methoprene is the IGR. There are now several “generics” of both Frontline Plus and Advantage II available, as well as topicals that are Permethrin-based.

For a more natural approach, Vet’s Best has a topical containing clove, thyme, and cinnamon oils as active ingredients. Rounding out this category are sprays, such as Advantage Treatment Spray, ShieldTec Flea and Tick Spray, and Espree Flea and Tick Spray. Davis Pure Planet has a spray that, although labeled as a poultry spray, is safe for dogs, cats, and puppies, and is effective against fleas, ticks, and mosquitoes! For those on the go, Espree and Vet’s Best both have convenient flea and tick wipes which are safe for dogs, cats, puppies, and kittens over 12 weeks of age.

Oral and Chewable Treatments

Oral treatments such as Advantus Soft Chews or Capstar are formulated to begin killing fleas very quickly and to work for 24 hours. These can be used daily; however, they are generally meant for a quick “knockdown” to be followed up with a collar or topical.

NexGard, Bravecto, Simparica, and Trifexis are just a few of the monthly oral flea treatments that require a prescription. Jeffers does not sell prescription items and recommends that you talk with your veterinarian.

Not Your Father’s Flea Collar

When it comes to flea and tick collars, they’ve come a long way baby! There is a new generation that says “goodbye” to the powdery, greasy, smelly, and frankly, ineffective collars of yesteryear. Here are a few great choices:

The Seresto flea and tick collar offers eight months of protection using a unique combination of Imidacloprid and Flumethrin. The active ingredients are infused within the collar and are released in low concentrations over time. The Seresto collar is not only waterproof and unaffected by bathing or swimming, but Bayer recommends that you not remove the collar as it might interrupt its function and disrupt the continuous release of chemicals.

UltraShield and Salvo flea and tick collars both contain Deltamethrin as the active ingredient, and both offer six months protection per collar. Salvo comes in a two-pack for a whole year of protection. The Natural Essential Oil Pest Repellent Collar for Dogs is infused with essential oils such as Citronella, Peppermint, Geranium, and Orange Oils, making them a natural alternative to collars with chemicals.

Hanging Tough:

Another type of protection for your dog is the SpectraShield Medallion which clips onto their regular collar. They will then be protected from fleas & ticks for up to four months. The active ingredients zeta-cypermethrin and piperonyl butoxide in the medallion remain effective through bathing and swimming. This may be the perfect solution for your outdoor-loving dog!

It is important to remember that treating fleas on your pet is only the first step in the process. For the next steps, please read our blog post titled “Flea Control Around the Home and Yard“.
