Featured Advice from Our Experts
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.
I've orderd this stuff 3 times and the first two it was great no fleas and no ticks at all. Still works great on the ticks but the fleas have returned. changing up
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!
I put on per instructions and my dog had fleas next day! Waste of money! Very unhappy...
