:: Late yesterday I heard a mass buzzing from our kitchen range hood. ::
Sounds more likely to be yellow-jackets. The range hood would provide them plenty of animal fat to feast on throughout the vent.
They can’t see at night and return to the swarm. They become docile. Have a brave soul wait at the vent outlet with a spot light and a couple of cans of wasp spray (MeCl brake cleaner is better, IMO) and turn on the fan after dark.
Fortunately, no. The critters we saw were definitely bees, and thankfully pretty docile, probably not Africanized.
