I have performed some spring cleaning/inspections on a few of my hives and have removed the screened bottom boards from them. Why? Because all they appear to be good for is collecting hive debris and moisture. I am also leaning towards the opinion that they may be one of the reasons I have so much trouble with the small hive beetle, and wax moth’s and even caulk brood in my hives. Are there benefits of screened bottom boards? Well yes I am sure there are, but in a humid environment with these pests always attempting to enter the hive the screened bottom board is just another way in.
So this year I am going to go without them and see what the results will be.
