Best flea control products

My two favorite flea products are Comfortis® and Trifexis®. Both products are once monthly, chewable tablets.  They contain an active ingredient against fleas, spinosad, and ComfortisTrifexis also contains milbemycin which prevents heartworms and controls some important intestinal parasites (roundworms, hookworms, and whipworms).  Fleas take a blood meal within minutes of jumping on a dog. In this way they are quickly killed by spinosad, a chemical that is much, much safer for mammals than for insects by virtue of differences in the nervous system.

We used to hear that “even one bite” could cause flea allergy.  But, the number of mites DOES matter and Comfortis and Trifexis kill fleas more quickly than other products, minimizing the number of bites.  They are not affected by getting wet or bathing in the same way that all topical products are, making them the best option for my patients that often require frequent bathing.  Comfortis and Trifexis are prescription drugs that must be prescribed by your veterinarian.  The choice between the products will depend on your pet’s specific needs and other parasite control prescriptions.

My favorite flea products for dogs

Protecting your dog from fleas is much easier than it was 20 years ago. Back then, the best we could do was knock the flea numbers down, but it was challenging with the products that were available.  Lately, the problem is knowing which of the many products out there is right for your dog. I’ll give you my 3 favorites, starting this week with number 3:

Vectra 3D is at the top of my list for topical products (spoiler alert: the top two are given orally). It combats fleas (plus ticks and mosquitoes) on three fronts:

1.  One ingredient (dinotefuran) over-stimulates the fleas’ nervous system. It acts on an insect nervous system receptor, leaving a wide margin of safety for mammals.

2. The second ingredient is permethrin, which helps repel mosquitoes, kill ticks, and fleas.

3. The third ingredient is an “insect growth regulator” called pyriproxyfen.  This ensures that even if eggs are laid by a few surviving fleas, they will not result in an infestation.

Vectra 3D is quite safe for most dogs if applied according to the label, but always consult with your veterinarian for recommendations concerning your individual dog.
