Like,call-m-all,said.Waxed dirt under the trap,poleyester fiber under the pedal,just enough buckwheat hulls to cover pedal and jaws and finish off with waxed dirt on top.Never will freeze up,unless you set it right in a real watery place.Mine gets rained on,snowed on,and still goes off below zero weather...Just remember,never set your traps in a low spot,where water will constantly run into where you set the trap.One other thing,you don't need no pan cover,when making this set and no wax paper under the trap,i see to many guys do this and it just makes matters worse.The ground needs to absorb the water and melting snow.
