I can think of only five types poisonous snakes that are native here in the U.S., Rattlesnakes, there are many different sub species of them, they all rattle though, Coral snakes, Copper Heads, Water Moccasins and Cotton Mouths. Maybe the Cotton Mouths and Water Moccasins are the same
My messages is most of them help us, not harm us
I use to catch a lot of snakes when I was a kid, mainly Garter snakes, Gopher Snakes and a few racer snakes, the racers were really hard to catch due to how fast they could get away
Most Rattle Snakes will stand and fight with you by trying to bite you if you bother them like trying to catch them
My message is don't kill them if they are not trying to hurt you, let them go away instead
