Default Trifexis - Ineffective on Fleas?

I have found a few fleas through the winter, and my dog itches like crazy. I recall when taking Comfortis, no fleas and no itching. Thinking of switching back to Interceptor and Comfortis. Before discussing with the vet, I was wondering if anyone else has had this issue? I know of another who had found Trifexis useless in the flea dept. For all I know, it could be the cause of the itching.
