A snake can squeeze thro9ugh some darn small openings, and I find it
hard to belicve netting alone is going to restrict a snake fropm
getting in a typical pond.......contrary to what McKoi
says..........

I suspect you are correct. I used to catch and keep snakes. My first
attempts involved making a simple box, getting some screen, and stapling
the screen to the inside of the box hole. The snakes always escaped,
until I learned to completely pin all edges of the screen with a wood
perimeter on both sides.
