I used a lot of colony traps on summer rats.
Watch out using baited 110s,you will find waterfowl all over the place.
Set up the den holes,summer rats are about the only time,I use a rat lure.And watch out for snapping turtles,I got one in a 110,thought I was pulling up a rat.I had the business end of that snapper to close to my hand for comfort.
