Spinosad Flea Control for Dogs

Are you tired of unsightly, unhygienic flea collars and messy flea drops?

If so, there are several new, and possibly better, options out there for you. We’re going to discuss some of them today so stick around!

There have been many developments over the last few years in the area of flea control for dogs. One of those treatment methods is called Spinosad, an ingredient in flea tablets which provides your dog with on-going, 30-day flea control.

Spinosad is the active ingredient in the tablet whose trade name is Comfortis. The flea tablet is produced by Eli Lilly and Company and was introduced to answer the call for an oral tab that offers longer-term protection from fleas.

The Comfortis flea tablet allows a dog owner to spend less time and money on tablets. Traditional flea tablets such as Capstar are becoming less popular because, although the tablet kills fleas, pets need to be given weekly and even daily doses of insecticides in order for the pill to be effective long term. This poses a problem not only to your pet’s health but to your wallet as well.

In contrast, Comfortis with Spinosad allows a pet owner to give the pill to their dog just once a month in order to be protected. The tablet will also kill any fleas that are currently living on the animal almost instantly.

Spinosad Health & Safety Concerns

While much safer than some of its predecessors, Spinosad is still a controlled substance and can only be obtained by a vet’s prescription. Furthermore, while it is definitely a better option than Capstar, it’s still a chemical insecticide and may cause side effects. Some pet owners have stated that their dogs experience vomiting, reduced appetite and diarrhea after first exposure to the tablet.

Also, Spinosad products do contain ivermectin, which FDA studies show that there is some level of toxicity in products made with this ingredient. Additionally, these product should only be used in dogs older than 14 weeks and should not be used on pregnant or nursing dogs.

While the majority of pet owners have been pleased with the results offered by Spinosad based flea control products, it is important to note that there are natural flea control products available that provide a great alternative to a chemical based products like these.

    Two of my dogs experienced no side effects. German Shepherd and a Springer Spaniel Labrador mix. Third month I give them this tab. No fleas. Works great.

    Have 2 rescue Chihuahuas, now 7 & 17. Younger 8 lbs, taking Comfortis 4 yrs, older 6 lbs, taking 2 yrs. No side effects, no fleas.
    Prior larger rescue dogs: Corgi x Norfolk Terrier 18lbs, and Autralian Terrier x 40 lbs,took Comfortis for years. No side effects, no fleas. They lived to be 17 & 16 respectively.

    The health risks of worms from ingested fleas (from biting at themselves), risk of plague to dogs & people in our area, miseries from scratching, and miseries to all in case of house infestation make minescule and extremely rare risks of issues with Comfortis NOT a major concern.

  5. Ro Scott says:

    Comfortis does NOT contain ivermectin.
    The only active ingredient is spinosad, a “natural” and organic pesticide legally used on foods labeled as organic in California, perhaps the strictest state in the USA.

    Other ingredients make up a shape-able tablet and ad flavor.

    It might be legally actionable for anyone to claim otherwise.

    By calling Spinosad a chemical it seems you are implying it is a man made poison. Actually it is derived from bacteria. You can insist on calling a chemical if you like but you might as well call H2O a chemical t
