The wasps around here have such a tough exoskeleton that you would hurt them only with a direct hit with a hammer on a very hard surface. If your wife was hitting you that hard... well, maybe you two have an interesting relationship. I think the best idea is to remove jersey and jump about like Orikal. I ride in the mountains, it is more common for an angry wasp to attack me than for me to suck one into my jersey. They first usually buzz me and then start bouncing off my body angrily. Then they land and start to bite or sting. From what I understand they can bite and sting. Don't know which is worse. The Yellowjackets are usually the most aggressive. But I wouldn't want to mess with the Africanized bees. From what I hear, most Africans would rather be attacked by a lion than by a swarm of killer bees.
