A few years ago, we had a infestation of cicada-killer wasps, which I think are the largest wasps in North America. We had just dug up the front yard and had the grass re-planted. These wasps prefer recently tilled soil to dig their nests in. In the small front yard, I counted about 200 nests. They were easy to find since there is always a pile of dirt next to the nest hole. They mostly all contained a cicada which had been stung and paralyzed and then drug down into the hole.

When I went into the yard, a bunch of them would always buzz very close to me at very high speeds. At first, this was intimidating until I found out that it was mostly bluff. The males don't have stingers and the females usually won't sting you unless they get caught in your clothing or something similar. They are very, very hard to get rid of. You mostly have to wait until the end of the season. I had them for 2 years and none of the internet remedies seemed to work, including pouring ammonia down the holes. Some say to swat then with a tennis racket but that is easier said than done, since they are so damned fast. I'm sure the cicada population those 2 years had a lot to do with it. The first year we had the wasps, there were tons of cicadas.
Another interesting critter is the carpenter bee. They look just like bumble bees but they are solid black - no yellow stripes. They bore a highly polished perfect 3/8" hole in lumber and lay their eggs in it. For example, on a 2" x 6", they first bore about a 3" deep hole from the edge and then turn 90 degrees and start boring down the length of the board. They can be very destructive, especially if there are lots of them.
