Monitor mite infestations in your hive with our Mite Detecting Bottom Board. This bottom board is made of plastic that is easy to clean and reuse, and has a grid pattern that helps to count the mites. The bottom board fits under the hive, and has a sticky board that traps the mites that fall through the mesh. The bottom board also has a sliding tray that can be pulled out to check the mite count. Use it to detect and manage varroa mites, the most common and harmful parasite of honey bees.
