Plastic Disk Entrence
- www.betterbee.com sells these in six colors $2.50 ea when you buy 10.
I drilled a two in hole about 2/3 up on front end.
May tape part of the hole this winter or just use the screen over most
You rotate the disk from, 1. full opening , 2, queen exclude, 3, screen
& 4. all bees.
Very handy to control the entrance instantly when installing bees or
any other time.
