I am planning on doing several splits as soon as the time is right. I am at a dilemma as far as oil pans or trays are concerned. I have made my own, customized to fit properly in the bottom holding box, (wall to wall) but this takes time. I have made them from flashing. Which is not so cheap when you add up the time and material. I also have made some from plastic coated foam board that you can easily purchase at any dollar store, or Walmart etc with the advantage of making two Nuc size trays from an eighty-eight cent board. but takes time. What I am hoping to find is some type of material that I can simply (paint) on the inside of the bottom board box which holds the oil tray, thus eliminating the oil tray, and will dry and set up as similar to a plastic finish. I have thought of fiber glass. But as I said am hoping to find something which sets up similar to plastic. Does anyone here know of such a product? I am persuaded that the entire bottom of the hive should have a screen to be completely effective against SHB, along with a wall to wall oil containment beneath that area. My theory is a partial oil tray or pan is not, or cannot be as effective as complete bottom coverage. If a hive beetle happens to fall through the bottom screen and misses the pan. It can simply crawl back up, through the screen and live to slime the hive on another day. This is something that I can't tolerate if at all possible. Once they fall through the bottom screen, I want them in the oil. Dead and done.
Thanks, Phillip
