you might try those instead. I think i bought a pack of 6 or something off amazon last year. Work well and you can load them with cooking oil which attracts the beetles but is otherwise harmless to the girls.
Mine is a screened bottom board made just an inch deeper than most. The dry board goes in while I powder sugar the bees. It comes out immediately after, and the sticky board goes in for 24 hours. The next day, the tray of vegetable oil goes in and catches mites and hive beetles, sometimes in pretty large quantities. Any slimy, wormy frames get frozen and replaced 2 days later.
