    There really isn't anything that does a good job against fleas, especially in the summer. Advantix is my choice for attempting to "thin the herd," so to speak. Over time it seems that the fleas become resistant to whatever you use. I didn't see your warning not to use the name of other retail producst, so I apologize for using a name earlier. I do use an oral medication that kills fleas in the last week of the month (but not often and only in the summer). Also spray dog beds and carpets, anything that's a fabric where fleas might make a home. I know there are some newer products for flea and tick control but they are even more expensive.

    I bought it as a preventive method to be used monthly. NY state was hit with warm winter, spring, summer and now fall, so there are a lot of ticks, fleas, lice all around. I really hope for the good results.
    It was not easy to administer the medicine. It is topical and had to be "spread" over the animal's back. Could not get it as neatly onto the determined spots. But, I guess, with practice and my dog's familiarity with the procedure it will get easier and more beneficial.

        Easy application to apply to dog and soaks in 24hours. Like that it has biting insects added to fleas and ticks. More coverage over mosquitos to help in preventing heartworms.
