Going through so old trapping stuff in the loft in my son's barn. Found numerous urine that are atleast 8 years old. Use it or lose it?

I have part of a gallon of coyote urine I bought from O'Gormans around 1990. It still smells the same now as the day I bought it.

Keep it and see what happens this season… if it works good deal, if it doesn’t, you aren’t out nothing.

Good clean urine will last forever as long as the cap and enclosure are still in some what good condition. If it is a metal cap I would replace it if you can get one the same size. I have some 20 plus years old I save for special circumstances in the field. It is very strong and dark.

I would never hesitate to use older urine. Even soured urine will get results from my field tests and use. If I want to create a new marking scent area I will often use what I deemed poor quality urine that I won't sell.

Dump 4-6 oz. on my selected marking object and let nature take its course. It will develop a life of its own in a few weeks. Come season I will catch several fox and coyote on that scent station.

Speaking of urine, has anybody noticed their urine going skunky after eating asparagus? Pooee

I have numerous gallons of 30+ year old bobcat urine. pull the cap and let it air off for a couple hours and its good as new.

All I know is when I go in the yard, my wifes male Peke can't wait to cover it, lol

Wouldn't be surprised if it works on all K9's....lol

Yep

I have a half gallon from around 95 .........can't remember where I got it
