You just have to deal with them. The most dramatic event occurred last week, when clouds of flying ants surprised Tigers fans and descended on Comerica Park in Detroit. Insect experts believe higher temperatures coaxed the ants to leave their colonies. The game continued, but players in the Tigers bullpen kindled a bonfire to keep the ants at bay. Of all insect pests, mosquitoes may be the most annoying.
Ants are relatively harmless.
Yet yellow jackets represent the greatest danger to humans. For people allergic to yellow jacket venom, stings can cause nausea, itching, vomiting and even unconsciousness. Severe reactions have led to death in 30 minutes. We're used to seeing these guys come out gradually, over the course of many weeks. That didn't happen this year.
