  • • Cocoons can be refrigerated until the appropriate conditions exist for release.
  • • Place cocoons outdoors by May 1 to help ensure that bees emerge in good health with sufficient energy to begin their work.
  • • NOTE: Spring mason bees are not recommended for AK or gulf regions of FL, AL, MS, LA and TX. Current agricultural restrictions prohibit the shipment of mason bees to the state of HI, and other countries outside of the continental United States.

While most customers successfully raise gentle bees, it is important to understand that bees are wild insects and may not nest in your yard, may be eaten by birds, and may not emerge from their cocoons. We cannot guarantee survival, pollination of crops, or reproduction of bees.
  • • These bees are gentle, typically non-aggressive and rarely sting, While there have been no known reported cases of anaphylactic shock in association with these bees, the use and handling of solitary bees may result in allergic reaction for some users.

Adult bees may emerge during shipping between February and May. Mason bee cocoons can become dehydrated in your fridge and cocoons should always be kept out of direct sunlight. Please carefully follow the mason bee care instructions included with your bee shipment.

Additional Information


Bee cocoons will arrive inside a small cardboard box. Larger cocoons are female and smaller cocoons are male.

Cocoons must be stored under refrigeration to prevent them from waking up from winter hibernation. Use our HumidiBee (cocoon humidifier) to keep your bee cocoons moist in the fridge.

When daytime temperatures have reached about 50-55F, place the bee cocoons in the bee house. Place the box of cocoons on top of the nesting holes with the lid open. The bees will emerge from their cocoons and crawl over the nesting material.

Please note: Bees need open flowers for nectar and pollen.

  • For bee-raising success, ensure: pollen, mud, fresh nesting holes, and a correctly located bee house.
  • Please do not use drilled blocks of wood or bamboo tubes due to pest, disease, and mold buildup. Nesting holes must be easily opened to clean and remove mason bee cocoons in the fall.
  • Sign up for our informative BeeMail  newsletter.
