I agree with Rick (as usual!
).
And the best cure for those visitors is deer fencing at least 8 ft high! Where we used to live in Oregon, the Fish and Wildlife Dept would provide the materials for free. Couldn't hurt to ask.
We were only fencing an area about 50 ft by 30 ft and they gave us the posts and fence material. All we had to do was go pick it up. Of course, that was in another country far away...
