Reviewing the active ingredients contained in Kirkland flea and tick control we find the following:
- 30.0% Etofenprox -CAS 80844-04-01
- 3.6% (S)-Methoprene CAS 65733-16-6
- 5.0% Piperonyl Butoxide Technical – CAS 51-06-6 (butylcarbity (6-propyliperonyl either) and related components
- 61.4% Other ingredients
These are to be the exact same ingredients used in “Bio Spot Defense Spot On.”
It appears that Kirkland flea and tick control is just a generic version of Bio Spot Defense Spot On. Since the Kirkland product has a limited history and there are not many reviews available yet, we can look to Bio Spot Defense reviews to see if this product has been effective. The products are identical, so we can safely say that the results will be the same.
Upon a thorough investigation of pet owners’ reviews of Bio Spot Defense, I have found an overwhelming majority of negative experiences with the product. Looking at reviews just from PETCO, the general consensus is that the product does not work. To summarize users comments, they basically say that the product is “horrible, bad, it doesn’t work, and it also leaves your pet greasy.” Negative reviews from Amazon include comments like, “worse than useless, disappointing, far worse than the original, Bio Spot hurt my dog, don’t waste your money.” Although difficult, I did find two positive reviews that say the product works if you apply it correctly.
Here is a video review created by a user that shows the typical experience with Bio Spot Defense. Summary: It doesn’t work!
In regards to safety, I found numerous reviews where pet owners complaining of skin burn at the site of application, which is found for almost any topical flea and tick medication. Although there were some complaints of side effects, there were many more complaints about the ineffectiveness of the product. There is not much reason to discuss the safety of the product if it can be concluded that the product is not effective in the first place.
I have been using flea and tick meds on my dogs for a long time and I regularly research the various products on the market. I can safely say that Bio Spot Defense, and consequently Kirkland flea and tick control, are not up to standard. There is an overwhelming majority of negative feedback about Bio Spot Defense and we can expect the same in the coming months from users of Kirkland flea and tick control, which is the exact same product. (Edit: Results are in: See horrific details from users in the comments section below). I would not waste my time with this product. In the words of various pet owner reviews I encountered, “You buy cheap, you get cheap.”
Kirkland Flea And Tick Control = Bio Spot Defense Spot On
In summary, Kirkland contains the same exact formula as Bio Spot Defense Spot On. If you use Kirkland, you can expect the same results as those of Bio Spot Defense users. Kirkland has basically taken an unsuccessful, ineffective product and made a cheap, generic version of it. This reveals something about Kirkland. It basically shows us that they are out for a quick buck and obviously don’t really care about animals. Releasing a low priced product and putting it alongside Frontline Plus at Costco, they know they are going to get sales, and that is ultimately their goal. By the time the market figures out that this product doesn’t work, Kirkland will already have your money and then when sales slow down, they’ll move on to the next thing.
If Kirkland was smart, they would have released a generic version of Frontline Plus and put it up against the brand name version in Costco and other outlets. In my opinion if you are going to make a generic version of a product, at least make a generic version of an effective, proven product like Frontline Plus. Fipronil, one of the active ingredients in Frontline, is now out of patent and available for use in generic products.
Generic Frontline Plus Instead Of Kirkland?
If you are looking for a budget solution for fleas and ticks, then you may want to try the generic version of Frontline Plus, which we know works well for most pet owners. Now that Fipronil has been released from patent there are new Frontline Plus generics available. One generic that has the same ingredients as Frontline is Fiproguard.
