Venomous snakes will find a way to let you know they are there they'd rather not waste their venom on something they can't eat...not to mention it has been proven and documented that a venomous snake will let you pretty much step on it with out striking so long as you don't reach for it.....as far as children go well they should be educated first and foremost about what is safe and what isn't or even to back away when they see a snake and get an adult there are much better ways to go about this than just killing on site
