Why are black widow spiders not affected by their own venom?
Priceclass
Great question! And also, why aren't snakes poisoned by theirs? In general a creature that uses poison in some form CAN die from their own bite in the same way that you can die from your own stomach acid, urine, feces, bile, etc. if it gets into your blood stream. Various organs have their own fluids and microbial life that should not get into other organs! What might be even stranger is that you have bacteria in your mouth that can kill you if it gets into your lungs, and bacteria in your urethra that causes great problems if it gets into your bladder!
