Orchard Mason Bee cocoons arrive in a small cardboard box with 9 female and 16 male bees. They are ready to be placed outside in an Orchard Mason Bee shelter Spring, when temperatures reach 49 - 55 degrees Fahrenheit for 3 to 5 days. 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, inspected, sorted and have a fully formed Orchard Mason Bee inside.
