We start our hunting (usually) mid Oct. in N.W Ill. & N.E. Iowa.
We use it from then on. Our season goes into Jan.. if we are still Bowhunting in late season-yes, we use the same scent.

In Ill. after the Gun seasons we usually don't venture out until after Christmas-takes Deer time to settle down again.
Our Iowa Bow season runs all through Nov. I Bowhunt very little after that as I've become a fair weather hunter in my old age.
I killed 2 Deer last year-1 just b/4 Thanksgiving that followed my scent trail & 1 in Jan. that did not. I did not hunt any in Oct. as my wife was very sick,

Don't get me wrong-in our day, my brother & I were out there right up till Gun season-1st day after & if it was 40 mile an hour winds & 6' of snow & 10 below we still went. You know-your a little nuts when your younger & I was that way until about 55.
I will be 68 in Nov...
