how to run into a swarm of angry bees and not get stung

A while ago some friends and I were sitting around talking, sharing stories about work and life, when one of my friends began to tell us about an experience he had with a crazy bug exterminator he hired to get rid of some bees in the building that he oversees. This exterminator had something just slightly out of whack going on in the head but somehow he still proved to be very smart. He was an odd guy and did strange things, like trying to find garden snakes in the area so he could have them for dinner. Anyway, my friend called the guy up told him about the nest/hive and waited for him to show. When Mr. Exterminator showed up, all he was equipped with was a push broom and his eccentric personality. My friend as anyone else would,  expected more but he knew the guy was a little odd so he didn't question him. He simply showed the exterminator where the nest was and went across the way to watch safely from afar. What happened next was pretty amazing. The exterminator went straight for the nest and swatted it, then a huge cloud of angry bees quickly appeared as one would expect. The exterminator ran into the angry swarm, swatted as many bees as he could to the ground and then he would stomp them after they had fallen. He then would run out of the swarm only to run back in a short moment later.  For the next 15 to 20 min my friend watched in awe as this man ran into the swarm, perform his swat and stomp dance, and run out just to do it all over again. This went on until all of the bees were dead....he didn’t get stung once! After it was all over my friend told the guy he saw everything and he asked him what he was doing and how he did what he did. What he explained was pretty suprising.The exterminator explained that whenever he ran into the swarm he was holding his breath and he only ran out because he was getting air. According to him bees react aggressively to CO2 and as long as one doesn't breathe out the bee’s wont (or at least will have trouble) attack. When I heard this I was a little skeptical, so I did a little research on my own. From what I read, carbon dioxide has an aggressive affect on bees; apparently carbon dioxide can enrage bees and provoke them to sting once they detect it. It seems as if there was a discovery channel program on bees where the host tested this hypothesis, proving the theory to be true. It’s astounding to me, but I'm never trying this, imp not that crazy.
