My dad always insisted that if you don't bury a rattlesnake head there's a type of wasp that will eat the head, then become as toxic as a rattlesnake. I know it's not true, but it's one of the things he grew up hearing.

Another is the woman whose husband was killed by a rattlesnake. She gave his boots to a hired hand, and he almost died. After inspecting the boots they found a fang left behind when the snake bit the husband.

If it lasts longer than 4 hours, seek medical attention
