How is it best to deal with muskrats in lagoons
We have muskrats in one of our lagoon and have done trapping but are surrounded by wilderness and fear just more will keep coming.
What have you done to deal with muskrats?
How do you assess their impacts on lagoon liner integrity? Do you recommend using monitoring wells? Checking groundwater quality? Our discharge is immediately beside a lake where we discharge to. Thanks.
PSEaG marsh reclamation in south jersey Cumberland county used rock in the burms to stop digging ....Birds like owls, blue herron, eagles, eat muskrat....Trapping might be the most practical way ....Conabear traps or a homemade havahart trap but is submerged in the runs to kill .....In areas where the rats are digging ..cover areas with galvanized chicken wire...... probably not practical....hire a trapper ....
