how does a deer smell it all the time?
I wouldn't say all the time, but how many times you drive by and see someone burning something in a year's time? Limbs, trash, leaves, fireplace, cleaning lots off... and so on.
Deer won't associate danger with the smell and the odor overpowers your own scent. Been using the smoke treatment for years and it works great. Only reason I buy scent-away is for my boots.
