Corrugated plastic squares for use in application with CheckMite+™ in treating Small Hive Beetles. Simple cut out a slot in the corrugations and place Checkmite+ strips in the gaps. The squares are placed on the bottom board or on top of an inner cover where the beetles hang out. The bees corral the beetles into the squares where they come in contact with the Checkmite+ strips and receive a lethal dose which kills the beetles. It is also important to use a ground drench when treating for the Small Hive Beetle.
