You would think that the mfr. of that product would adjust whatever they put in it to take care of the problem in a specific area of the country.
They have, actually.
Frontline TritakIf you click on the "View States" link, you'll see that most of the states it's available in are in the south. Last year it was only available in southern states, but I see they've added a few more.
But for whatever reasons I don't hear a lot about this product on the various pet message boards I belong to. I don't recall ever seeing any info about it at my vet's office (and they have plenty of product posters and brochures around). I don't know why it doesn't seem to be more widely available in the states where it's sold.
