During some hive maintenance last week I decided to try to surgically remove the sliding corflute from my screened bottom board. The girls had done an admirable job of propolyzing it to the bottom board and no amount of tugging was going to make it budge.
Surgery turned into outright demolition — I ended up having to tear everything apart, get into the underside of the bottom board and to a vertical cut along the corflute, then tear it out on each side. Whew. Good thing I was completely suited up — the girls were PISSED.
I did notice one thing that made me want to investigate a different, longer-term solution to SHB and other critters that fall through the screen. Between the screen and the corflute were dozens of live SHB and even a wax moth larvae (I think — it was certainly something wormy!)
In my trolling around on the internet I saw a Freeman beetle trap… It looks like just a tray (in place of the corflute) that holds oil to trap and suffocate the critters that fall into it.
I also found this “Neverwet SHB barrier”: https://www.youtube.com/watch?v=FfnefkJSfBs&t=8s
So my plan for the spring: Build a new bottom board using the “Neverwet SHB barrier” (above) and something like the freeman bottom board method…
Where I need help:I need to source some trays that are sized to fit (roughly) into 8 and 10 frame bottom boards (and this can be a “close” fit as I have to actually build the bottom boards and can make some adjustments as necessary in their design. Has anyone looked at/done this?
