Advantage flea control

[Old Geezer]

I have been using Advantage for several years now with very good results.
However recently it is not doing the job well. I am seeing fleas in ten days after treatment. I am wondering if he has become immune to it. From what I have found out there is no experation date for it. I did buy the last box on Ebay. I am beginnning to wonder if it could be counterfeit as that goes on all the time with many products including medications.

I'd buy a new box somewhere local, and see if that works better.

Yes I think I will do that. Seems strange it worked for so long and
suddenly stopped working as advertised.

I use Revolution on my cats, as it ALSO works as their monthly heartworm so I don't have to do 2 things. It also addresses hookworm and roundworm and ear mites.

Umh. Good idea. I thought it only protected against fleas and ear mites.
I know he has ear mites.

I've always used Revolution. It works great!!
