Re: Dadant Screened IPM Bottom Booard
I have bb similar to what you describe but from a different vendor, honestly, I prefer them much more than the others with a gap I have. I get a little build up and on occasion a few moth webs, but easily falls out when I check them. I like the closer seal during cold months and pulling them every few weeks hasn't be an issue.
I also find more hive beetles, bees and moths on the boards that have the wider "gap".
