Ok. The title of this is going to sound really strange to the non hunting public. I had learned of this technique of baiting predators from a hunting forum. Here in Massachusetts we can bait for predators and hunt at night provided that we don't use a light source. To me that is silly as a light would aid in target identification but the powers that be fear people would illegally shoot deer. Personally speaking, I don't think so. Those people will do it anyways.
The way to use a meatcicle is to take a five gallon food grade pail and spray the inside with PAM or other non stick cooking spray. Put in meat scraps about one third of the way up and then fill it with water. Let it sit overnight to freeze and then bring it to your stand location. It is pretty simple to use.
I have set up a Trail camera to record what manner of wildlife would come to my meatcicle at one location I hunt in. So far the only animals that have approached it were red and gray fox. crows and a fisher.
Next winter I plan to set up a couple more meatcicles in the hopes of attracting a coyote. We'll see how well it works.
