Everyone I hunt with, and know, uses the popular Tink's/Code Blue/Golden Estrus including myself. And I am sure everyone on the surrounding properties is using the same. So everywhere a buck goes.... is he smelling the same pee manufacturer's product? I always thought, but have never tried, using some doe pee from a small deer farm I found online, or a smaller company, etc. Would that even matter? Or is Pee Pee? Just trying to differentiate my scents from others. Any other ideas?
Some companies use other scents to attract deer on top of deer pee. Also using preservatives to make it last longer on the shelf. The small farm fresh pee will definitely work it will expire quicker so you'll have a smaller window of time to use it. I've seen some people put it in the fridge to help it last longer. You could also shoot a doe and cut out her bladder and use that.
I think it's all the same, ammonia is ammonia. You can even use your own urine in scrapes and it will get the bucks curious.
You said Pee Pee, lol. Sorry couldn't help myself. I group doe piss in with other gimmicks...evercalm is the only scent product I ever used that was consistently useful. Had some luck with the old buck bombs but that wasn't conclusive.
