A02 Mason Bee Cocoons

The cocoons (16 female, 9 male) are ready to be placed in nesting boxes or cans in the Spring. The cocoons need to be stored at temperatures at approximately 42 degrees until they are placed outdoors. When the outside temperature has reached 55 degrees or higher for 3-5 days, it is safe to place your bees outside. These are loose cocoons, not in tubes. If you will be storing your cocoons in a refrigerator, you may want to consider purchasing the Bee Safe Humidity Box to help maintain proper humidity for the cocoons until they are ready to be placed outside.
