Features of the Sundance Pollen Trap are, a cover to prevent hive debris from entering the pollen drawer, a stainless steel screen on the drawer, heavy duty galvanized wire cloth, a rear opening drawer, and bee exits that do not require going through stripper screens. You can switch from collection to non-collection so that the trap can be left on all season. This is the only trap that can be used while using sticky boards for mite detection. Comes with instructions. Fully assembled.
