Having raised alot of snakes in my "younger years", I will kill every copperhead I see on my place. they seem to have a "i'll hide till they get close" attitude. I raised them to feed to King snakes. The only snake that has bitten me was a Diamondback water snake, non- poisinous, commonly thought as a water moccisson since they almost look identical and probably the most aggressive snakes I have ever had.
I used to have problems getting my (5 yr old daughter at the time) to wear her shoes when she went ouside at the farm, then one day I found a rat snake about 5-6 feet in the yard, I took her outside and showed her the snake so she would understand what Dad ment, the snake was harmless but it made the right impression. I personaly respect snakes and their role in our enviroment but there are limits. As far as Wasp..LOL a few on the porch are good for the occassinal salesman..LOL I don't bother with them either unless they are on the tractor or deer blind as before mentioned. You know your having a bad day when you go to move a square bale and realize there is a bumble bee nest under it, now thats an aggressive monster and sting, wheeeew!
