In most cases these animals will not quit and move on without some strong “persuasion”. This means you’ll need to trap and relocate them. As you’re probably learning, they can cause quite a bit of damage to docks. They will mostly chew the styrofoam and/or plastic floats doing permanent damage. They can also chew the dock itself depending on the kind of wood used to construct it. The Easy Set Live Beaver Trap is a good option for this type of problem but you could use some other devices we have featured in our beaver control article.
