Orchard Mason Bee cocoons from Knox Cellars Mason Bees arrive in a small cardboard box with 10 female and 15 male bees. The cocoons should be stored at temperatures approximately 38°F 42°F until they are placed outdoors. These are loose cocoons. They have been cleaned, sanitized, inspected, and have a fully formed Orchard Mason Bee inside. 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 placed outside. Cocoons are sent between mid October and April due to the OMB life cycle. As tempters increase in late winter and early spring OMB may emerge during shipment. Please, order early as we can not control shipping or temperatures 
For bees sake order winter 2025 or very early 2026!
