When to Start Using Doe Estrus?

Doe in heat urine is best used during the rut (or, sometimes the “earlier rut” that happens when some older does sometimes get a biological advantage and go into estrus 28 days sooner than the other younger does).

Can you use too much Doe Estrus?

The doe are not in heat yet, so the bucks are not chasing and you shouldn't be using an estrous scent at this point. You can use a normal doe urine, but estrous is from the point in time the doe go into heat. I would start using it around October 28th or so until the end of the regular archery season.

Can you use doe estrus in early season?

It is not unreasonable for a mature doe to come into heat early, so yes it does happen. Give it a try just don't use a lot, very small amount. The problems with guys using scent is that to many use way to much and it spooks deer. Fresh, fresh, fresh is what I have read on this topic.
