It has been some time since I have temperature tested any of our lures and baits. It never was a problem with the very cold temperatures and the product not being applicable in years past. That work work was done many years ago.
Interestingly, Seth " Yes Sir " brings up some good points on the cold impacts the products that we use.
I put out a sampling of most all of our products last evening. Lures, baits and urines. I knew it was cold and more cold forcasted for the next few days. Below zero and them some.
My results are as follows >
The urines froze solid and crystalized. Red Fox, Coyote, Bobcat and Grey Fox urines were all frozen. These were all in 16 oz. plastic squirt bottles taken off the retail sales shelf.
These urines would all need some antifreeze to keep them fluid enough to use in the kind of temps we had here the last few days.
That or keep them in your vehicle between stops, in a jacket pocket etc. to keep them in a warmer environment. Just keep the cap on tight.
They all had good odor even in the frozen state.
It was -5 here over night with 30-40 miles an hour straight wind chill added to that cold. It's around 2 degrees currently at 7:30 am.
These are extreme good temps to give a good testing of the freezing properties of a product or element.
Our cat, beaver and egg baits all got tightened up, but easily workable with a butter knife for application use.
I also briefly odor tested each product for scent odor vapor and they all smelled the same to me.
Don't think for a minute that this kind of cold holds that odor from releasing. The extreme cold may reduce some of the odor push but definitely will not stop it.
Now if a product is frozen solid the odor release will be greatly reduced but not diminished.
Just my 2 cents from my experience here.
I had some wolf pudding (wolf crap, urine and glycerin) and it was pretty dang stiff but you could still dig some out with a stick.
