I am building a few Screened bottom boards, with 3/4 in. pans underneith to hold mineral oil, all information I believe I have found says " use # 8 hardware cloth "
I understand a adult small hive bettle is too large fit thru # 8 wire cloth, would
not # 7 hardware cloth work just as well ?
If i am correct, bees cannot pass thru # 7 but small hive bettles can.
Any comments will be appreciated.
Oh one other thing. Why isn't plain aluminum window screen mentioned for thing like bee robber screens, vent covers, etc . Just wondering
