If you are like many lakeshore property owners you have probably spotted muskrats swimming near your shoreline in warmer months. Sometimes they can become a nuisance for landowners by causing shoreland to cave in over their burrows. This activity can erode your shoreline or cause sinkholes in your lawn. Arnold Groehler is an Animal Damage Control Trapper authorized as an agent by the DNR to remove muskrats from your shoreline. Permission to access your property is required. Arnold typically begins trapping muskrats in early spring (February or March) when the ice first goes off the lake. If you are in need of his service, he can be reached by email at jmgroehler@aol.com or by phone at 262-490-9363.
