In the last few weeks we occasioanlly have a downpour of tiny winged insects from the ceiling in the bathroom. They are mostly dead and the rest are very slow moving. Less than a year ago we opened up all the walls and replaced the old (wallpapered) panneling with sheet-rock. At the time we know there was no termite activity in the wall beams (or anywhere else that we could see). The beams were also treated with copper green. Are these termites? Any suggestions before we contact a termite company?
