A white corrugated plastic tray that slides into the slot of most screened bottom boards. Did yours get lost, stolen by the wind or torn up by an animal? This is useful to count mite drop when doing varroa treatment and to help control the amount of ventilation a hive has through the screen bottom board. Easily cut to size with a razor knife. This is plain white on both sides but you can draw lines on the board if your looking to count mites. Other places charge $8.00 for a board with lines drawn on one side. This is made for a 10 frame hive but is easily cut with a razor knife or kitchen scissors to fit smaller hives.
