I hope you have a good time shrooming. Let us know how it goes. I know next to nothing about shrooms where you are.

When you are looking at snare sets remember that they have to be where the animals go.
You might be able to lure some animals to snares off their trail with the right bait but it is much better if you can get the snare right on their trail. Sometimes it can even pay to make a trail for some animals like beaver and muskrats. In snow a lot of animals will follow in a man's footsteps. Deer are famous for that. They prefer not to break trail if they don't have to. In deep snow they get so they will starve in their yards before they will break new trails to food.

T_Co mentioned the squirrel pole. Yes they do work, but even with those you need to have the squirrels around and willing to use them. If you can lean one right into a tree with a drey (squirrel nest) in it the snares will stand a better chance of catching something than if you set it against a tree with no traffic.
