nypondguy - You are to be commended for providing habitat for beneficial snakes. However, many people have an irrational fear of snakes. I have heard that mothballs will repel them, but personally, we have few poisonous snakes in my area, so I encourage them. In fact I hope to build a large snake hybernaculum this year.
I used to be a huge snake fancier, trying to catch and identify every obscure species. I lost interest, but know my snakes like some pondmeisters know their fish. I guess I've been bitten a hundred times, and just laugh at it.
Still,,, when I walk up on a snake, I get a tingle up my legs a split second before making it out visually, proving we have an innate fear of them.
Mothballs do a great job of repelling
me. I rather the snakes... just not too many of them.
