Police are warning Hudson Valley residents after a snake that can kill a human was found in a homeowner’s yard.

The above picture was taken in Upper Nyack. Clarkstown Police say a venomous copperhead was found by a homeowner in the yard.

Police say the venom from the snake can kill humans.

If you ever encounter a snake like this the New York State Department of Environmental Conservation recommends you call a Venomous Snake Responder, licensed by New York State, to come and remove the snake if it doesn’t move on its own.

If you are bitten the NYS DEC says to seek immediate medical assistance. Commercial snakebite kits, which suggest making lacerations in the area of the bite and applying suction, are not recommended.

Authorities recommend you show this picture to children so they know to stay away.
