1. Snakes - I don't go into full panic mode if know they're venomous, but my blood pressure and heart rate go up a few ticks for sure.
2. Wasps - Years ago, my little brother was 4 or 5 and got stung by a red wasp through his jeans. I was only a few feet away from him and he was already to the point to where I had to carry him across the road to get him in the house. We sped to the hospital and got him the care he needed. *** This was before benadryl was OTC and of course we weren't aware that he was allergic to wasps so we had nothing on hand at the house. Needless to say, he is always packing benadryl.
***Hospital wasn't going to treat him until my mom could prove she could pay for services. At that time, she couldn't and they didn't give him an attention until a friend of our showed up to show proof that the bill would get handled. Dude was a rodeo clown - in the Cowboy Hall of Fame. You could hear him walking in the other side of the hospital cussing every one in sight.
3. Eels - I mean... wtf, man?
