Pond Boss Forums GENERAL QUESTIONS Wildlife Management Muskrat connibear traps and low water levels

Agreed, a 110 is the size you need. BUT, if the hole is out of the water, they won't use it. They only use them when the opening is under water.

Another tip, if you see a hole with a 1/2 diameter tunnel (a run) leading up to it under water, and it is all silted over they are not using that run/den either. If you see one has muddy water in it, they are actively working on it.
