They said good judgment results from bad judgment, so I'm fulfilling the traditional beek noob role by making a few mistakes. I could not find for the life of me screen material in 1/8" square, the hardware stores apparently only carry 1/4". I found some really good coated metal gutter guard screening though, it was between the two sizes. Anyway, the bees are getting through. This is a package bee hive, installed 5/21/19.
There are a LOT of bees hanging out now in the crawl space below the screen and above the floor. They're not building burr comb that I can see. I don't know whether or not to worry about it so I won't for now. All in all, the hive is very vigorous.
Has anyone else had experience with a less-than-sound screened bottom, and if so what was the result?
