I believe Long Island has no poisonous snakes.
Long Island has been rid of poisonous snakes for quite a few decades. Over a century actually. Just like in the western roundups the good folks here on Long Island rounded up all the rattlers/copperheads till they were gone. Plenty upstate and Jersey and Connecticut though.
I don’t mind snakes as rodent control. Just not ones with hypodermic needles filled with toxins imbedded in their heads.
