I need to put a couple smoke detectors in the grow room. They would go off every nice day I opened the window though as the bees find their way in and always go to the HID bulbs. Instant bug smoke and if they land on top, they stay and cook. I almost freaked out one day when I opened the door and the room was cloudy with smoke. I shut everything down and started searching with my nose, It didn't smell electrical but I was still worried, ended up finding a blackened bee carcass atop the 400w MH. I hate for bees to die but they just can't resist the smell.
