I know this thread has kept you on the edge of your seat all evening. Searching through some bug sites yeilded results that eluded the hive mind. I believe they are called "mining bees" and they are docile and present no threat. They don't work in hives, they build individual nests near each other. They like the sandy, dry areas they have chosen to nest in.
So what the heck are these things?
They have been multiplying rapidly. About two weeks ago I first noticed them. They are in my back yard. They cirle around low to the ground when they fly. They are capable of rapid flight to avoid the can of RAID. If you can land it on them, it will kill them, however there are hundreds of them and raid is four bucks a can and only lasts about 20 seconds.
These flying insects are building lots of little nests in the ground. Some have a mound of dirt around the entrance, some do not.
I nuked the area saturday with raid and about 15 lbs of Sevin (carbaryl). It did nothing. They might be building their mounds out of the stuff. Today there are easily twice as many nests.
The insects do not seem aggressive and don't sting. I've driven my lawnmower through them, laid down bug killier walking around all over with them... they don't seem to care.
The bugs are black, they have a yellow furry patch on the part behind the head. Those are the best pictures I can do with my camera. The bugs have some sand on them from rolling around on the ground to die.
My soil is sandy in the back yard. They like those areas best I think.
Do I need to unass the A.O.?
Kill them with fire?
Call terminix?
Run around and scream like a little girl?
Get an anteater?
Ask DrFriDge to borrow his spider collection?
Ignore the problem entirely?
EDIT to correct my title because I used the wrong word. Blame public schools.
