Moist air moves up into a bed of wood chips and is removed out of the hive through the screened vent holes without causing a draft.  Works 24/7 all winter long

Ventilates the hive in the hot summer months.  Chips are removed in the summer and The Hive Toppers is flipped and placed on top of the inner cover.  Ventilation without a top entrance reduces robbing.

Use above the feeder on top of the inner cover and The Hive Topper removes moisture from the hive while feeding.  Keeps the hive dry .
