So if I got bitten, no medical attention would be needed? (Exept bandaids )
A simple answer is no, but there would be an extremely small chance of a bad reaction. That said even python bites can cause infections that are potentially harmful. I guess you could say its much safer getting bitten by one than driving a car or living outside a heavily fortified bunker. Although if you are hypersensitive to other snake venoms i would avoid letting them chew on you. A defensive bite would be unlikely to cause any venom to enter your system(although that is a guess).
Would you seek medical attention for a green ant bite?
