They dont really look like that. If they do they are damn small as I have never seen them have you? Try feeding mycelium and seal up your lights. You can spray soda on there backs so they cant fly if they are going to fly into the lamps after they shut off to keep warm then get blinded and baked when the lights come on. If you dont have shades its not a problem and they will stay if its warm enough. 85 is real good.
