This is a screened bottom board but without the sloped entrance. It is made of radiata pine, has a stainless steel mesh screen. You can choose either a corrugated plastic or poly-metal mite tray.
The shorter entrance & design allow for a cheaper price tag and a lower shipping cost. All joints are glued and stapled. Comes with a corrugated plastic mite tray.
Using a non-invasive method to check mites using a mite-tray allow for frequent testing without disturbing the hive.
