Just opened a compartment in my boat. Red Squirrels have been in there. 6+ wires chewed thru, no idea where the other ends are. Boat is stored with a cover on in a pole barn. I thought moth balls kept the squirrels away, but I guess not. Plenty of moth balls in the compartment they were in. Is there anything that will keep Red Squirrels away? Thinking about paying for indoor storage somewhere, seems silly when I have space in the barn.
