doe can breed in cycles, and a first cycle can be in early OCT or even LATE sept, BUt MOST doe's come into heat in the Nov 5-20 range IMO
SO< any remaining will again go into heat again in Mid Dec and then LAN till there bred or time runs out on heat cycles

SO that said, a Doe Estrus scent can work any time legal hunting season is on
MOST all save it for the PEAK rut dates

But IT can be used any time you want

and its BY far NO magic in a bottle
seen it spook as many bucks as its lured in
SO< just saying

any time from OCT 20 th to about Nov 30 th would be MY suggestion for best results
