If it is a problem or infestation like you describe, and especially in an area where children will be living, then by all means, I agree something needs to be done. I was referring more to like when people see a random copperhead, rattlesnake, whatever, out in the woods or along a hiking trail, and kill it just because it is there. If it weren't for poisonous snakes...we'd have a lot bigger problems on our hands with diseases caused by rodents, and lord knows what else.
But as far as keeping kids safe in their homes & yards...absolutely, I agree with you wholeheartedly. Nothing is worth jeopardizing the safety of our families.
It's on my bucket-list to see & capture on camera an eastern diamondback rattlesnake in the wild. So far, I am batting 0.00 in that department, and having absolutely no luck despite spending countless hours on trails & in areas down in Fla where they frequent.
Those are beyond elusive.
