Flea Wars (Part 2) - Demystifying Key Ingredients

One of the biggest misconceptions about flea treatment is that switching brands is the same as rotating. Rotation of active ingredient is key in getting ahead of a flea infestation. The sad truth is, the majority of the products on the market today share a very few common active ingredients...

    "Best Tick Control Yet"

    I live in central Minnesota where ticks with several tick borne diseases abound. Frontline and Advantix Plus did not kill the ticks and often I pulled lively full ticks 24, 48 and 72 hours after application. With Certifect, although ticks still attach, I have never found a bloated full tick like I did with the other products. And many times I remove ticks that are dead. It would be nice if the ticks were repelled before they attach, but at least they are not getting a blood meal and surviving. I am re-ordering more Certifect today.

    "Great stuff!"

    Not sure why this has only one star so far. I am in Michigan with tons of mosquitos fleas and ticks. Since using Certifect mosquitos don't even come near my guys. Try it!
