Very easy to catch coons. dry cat food and a $1 can of mackeral. Traps dont have to be along creeks etc. We catch a ton of them no where near water sources and just on the sides of the roads. We have painted a few DP traps white to make them catch their eye more and set them in the wide open. Also makes them easier for us to see.
If you run feeders set multiple DP traps around them. We have several sites where we put 3 or 4 traps out and its pretty common the first few times in that spot to have one in every trap.
