Put regular size marshmallows in a small zip bag along with a small amt of cinnamon & flour. Shake well enough to coat. The flour helps keep them from sticking together, esp in warm weather. Put I under the trigger & set. Have caught many coon in D-P's at deer feeders using only this. For a booster, I sometimes add 1/2 tsp. of floating catfish food pellets on top. Other variation is to fill a small jar with deer corn &'add 1 a few drops of 1 of the following: anise, butterscotch, vanilla, almond, cherry or other type of sweet flavoring. Put lid on, shake it well &'let sit well overnight, then drop a few kernels on top of marshmallow. The kernels of corn will hold their scent longer than you mite think, and down here in the south the fire ants have a hard time carrying the shelled corn off. IMO, I laff every time I read where some guy says you MUST fill the barrel of the DP full of bait in order to catch coons. Of course, some of them are making &'selling DP bait. The above are inexpensive and work very well in my country. Since I run a multi-species line, I don't want to cross contaminate my canine traps & equip't with anything sticky, stinky, runny or gooey, so I only use dry bait in the DP's, but like them best anyway. Just my opinion, but based on a lot of experience. For the record, I prefer the Duke DP's over all the rest.
