I have read it is a good idea to alternate between ADVAnTIX and FRONTLINE -- I have three fur babies and was having a HORRIBLE time with fleas (and yuk... ticks) and the frontline wasn't working. I tried the advantix last month and it worked!! For the ticks my groomer recomended using flea and tick collars (summer months when ticks are the worst) and I have not seen a tick after using the collars
I also used the dishwashing for bath time if I find any fleas... it kills the fleas (you can see them floating in the bathwater) but does not prevent new ones. I use borax --sprinkling in the cornners on such and it seam to help.. hope that helps!
