Keeping carcasses from freezing

Do any of you put glycerin or propylene glycol on them?

Are these bait station carcasses?

Yes

I never have. It would take alot of glycerine and injecting into them. Not cost effective at all. Even frozen solid the animals you are after will still find them. Use a high powered call lure around them if you feel you need more reach and attraction.

Over ten days maybe 2 week period with temps never getting above the single digit or teens during the day .and 15 to 20 below at night..that was a brutal winter about 10 years ago. Coyotes cleaned those frozen pieces up no problem. Never underestimate a coyotes nose.
