I have a wooden porch swing that some carpenter bees have been living in for a while. They never bothered us once. Recently we found about a dozen of them lying (mostly on their backs) dead under the swing. We have absolutely no idea what happened and I can't find anything regarding it online. Could you help explain this weird phenomenon of a mini bee-jonestown massacre.
I don't know where you're located (profile update would help *hint*) but that happens here quite a bit. I've seen them fighting at certain times...maybe it was an all-out war?

Neighbors with insecticide?
Short life spans?
normal life span. at some point they start dropping like flies. unless they happen upon my b***h hive where they are
quickly dispatched by the girls. :-D
Maybe the swing is made from treaded wood?
