Post Updated onI finished our new Screened bottom board today, I added a Varroa Mite inspection mat that is just a piece of plastic. Part of the same sheet of plastic that is also the roof of our NUC box. The mat can be speared with a thin layer of Vaseline and then the mites get stuck on the board, which makes it easier to count them and also prevent them climbing back into the hive. Hopefully it will be a chemical free way of controlling Varroa. We will have to see if the Bee’s like the new base board, hopefully the new NUC will take off and this can be its base board.
