You will want to place the box traps in front or slightly inside there den entrances and make sure they are beneath the water like esshup has said. Muskrats are not the brightest creatures when it comes to traps, unlike some other critters, and are very easy to catch without any prior trapping experience. I wouldn't be the slightest surprised if you are to pull double digits out of your pond.
Ok you guys got me curious, Ive never heard of using the colony trap, when you say set it at the entrance to their tunnel, is that with the open end facing in towards the den, so that you catch them coming out of their den, or facing out, to catch them coming to the den?
Or does this thing catch them from both ends?
Ill have to do some research, maybe this is what I need, I have seen tho that many times they have more then one entry to their den.
I do know these little suckers can excavate a lot of dirt out of a dam.
