Glycerine or glycol for freeze-proofing urine?

Do you use glycerine or glycol for freeze proofing urine?

What ratio do you mix at?


I found "Vegetable Glycerine Oil" on Amazon. Is that the same stuff sold at trapping supply places?

Glycerine
1 pint to a gallon , 12 1/2 %
Up to 20% when -25°
Many different grades, know what your buying .

glycerine... I spray 1:3 with water in my sets to freeze proof them I don't know if urine would be the same.

I add some in a pint urine bottle about a inch on the bottom then shake it up I had some great yote urine from MTP this year did not need much at all.

These say "Food Grade" or "USP grade" vegetable glycerine. Is that the same as trapping supply places sell?

I got some urine from wieser, it was liquid at zero degrees. I never seen that before, so that's the lazy way of freeze proofing, buy it already freeze proof, lol.

Freeze out your urine.
The first thing In urine to freeze Is the water. Skim off the frozen water and you shouldn't have to add any additives to your urine. When you do this your urine will become more concentrated and will be stronger.

Hard to believe you can find any stronger urine than Andy's. I set the empty box he mailed it to me in outside, and the flies laid eggs in it. Had maggots crawling in the box in a couple days, and he had it vacuum sealed. Out of all the skunky lures in my packbasket, I can smell the bottle of fox pee the best. My urine post set has become one of my best sets the last couple seasons since I started buying my stuff from him.

USP seems to be the highest grade glycerin.

Does anyone know if that will be at least equal to the trapping companies?

He may freeze out his urine.
