Rattlesnakes are dangerous. They prefer to be left alone and do their own thing but they will bite when provoked. People are safe from rattlesnakes if they respect the snakes by not provoking them by stepping on their homes or trying to handle them.
RatZ are vermin which multiply. They carry disease and plague which they spread wherever they go. They destroy crops and eat food. They overrun homes and make them uninhabitable until the ratZ are exterminated.
Unlike the rattlesnakes the ratZ do not respect those who respect them. The damage from the ratZ happens everywhere the ratZ infest.
Nobody wants rattlesnakes on their property because the snakes can be dangerous. But if you get rid of all the snakes you will have ratZ.
If you want to live in a property without snakes or ratZ you better have the money to move to a gated wealthy community. Most of Mx does not have that money.
