If you've trapped an area for years and you know where coons are located year after year or know how to read sign, no bait or lure of any kind is needed to catch coons all night long. It's all about trap placement and location.

Shelled corn will attract every coon around and yet has very little smell. Given time coons will find it though. When I set traps for coons, I want to take as many out as possible as fast as I can, maintaining traps for a week or more can be difficult. Suppose you have an area to trap located near a sub-division where the coon population desperately needs reduction, but can't get but so close due to non-target catches. Would shelled corn, garbage, honey buns or dog food have the ability to pull the coons hundreds of yards to a location they could be safely eradicated? Possibly given enough time. Or you could use something that reaches far and wide, that a coon simply can not resist. Works much like a call, sometimes light calling works, sometimes you need to turn up the volume.
