Yep -- depends on where you live. I know some places in Canada don't even have any cases of heartworm or flea/ticks so nothing is needed... lucky them!

Here in Maryland, I use it accordingly. Well I give heartworm meds every month, it's not worth the risk to me not to. Flea/tick meds I just play by ear. Usually ticks here are terrible in the summer, however this year, I gave him Advantix in June and did not give again until two weeks ago (first week of October). Never saw any ticks. I probably will give one more dose in December (and skip November) unless I am seeing more ticks around. Last December, I pulled three ticks off him, so ended up having to use the stuff.

My usual course of action is to use Frontline from October-April and then I use K9 Advantix in the summer when ticks are usually worse. I prefer using Frontline because it does not contain permerthin but I like to avoid them all if at all possible.
