Bee's are dying?

If you watch the news you have probably heard that the numbers of bees on the earth are fewer and fewer. While we were in Utah you wouldn't have known it. I stopped counting the number of nests we (not me, Trey) sprayed. Some of the nests were too high up to reach so Trey would spray them and we were going to knock them down later, and before we could knock them off new bees would nest in them.
