Shelf Life of Deer Lure

[buck460XVR]

While older deer lures may work, do you trust them to work as well? Doe pee, Rut and Scrape type scents all stink, so your nose ain't gonna tell you they have gone bad. How does one know that the lure has not been contaminated(which happens more than folks think)? Older deer lures tend to have been used a lot too, so if one hunts in an area where the lure has been used to excess, effectiveness suffers. Similar to calling turkeys. While a certain series of yelps made on a particular call may work extremely well on opening morning, use it continuously over the season and pretty soon it is ignored. While deer lure manufacturers make all sorts of claims, how do we know really what we are getting? Does doe pee(estrus or not) collected from several deer smell like a whole herd as opposed to just one? Would that confused a deer more than attract? Same goed for those dominate buck lures? How do bucks know a buck is a dominate or a subordinate just from it's pee?

Lure?

Around here you would have more use for repellant.

How do bucks know a buck is a dominate or a subordinate just from it's pee?

I know that bucks can tell a doe is ready to breed by smell ..... detecting estrogen levels, IIRC ...... I do not doubt that they could assess testosterone levels with the same exactitude.
