I wouldn't keep them screened in for a day. The best option is to move them a few miles away the night before then bring them back the night after the BBQ. Or just leave them be how they are.
!. Believe it or not there are lots of bees that don't get home before dark, so you would be keeping them out the next day which wouldn't make them happy. And you would have to go to great lengths to keep all of the bees inside any net or large screen you might have.Hello,
My thoughts are:
1. cover the hive the night before with a large screen when all the bees are home.
2. make sure they have a jar of syruple and water to keep them through the day
3. Uncover them as soon as everyone is gone.
Anyone have any insight or suggestions?
