SPRING Mason Bees available February—April

  • • Release spring mason bees when daytime temperatures are consistently 55°F (13°C) or warmer AND there are open blossoms for your hungry bees.
  • • 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.


  • • A hot mail box can be harmful to developing or emerging bees. If you are not home during the day to retrieve your bees, consider having them shipped to your workplace.
  • • Select the Monday when you would like your bees shipped, allowing 1-5 days for delivery. When the bees ship, you will receive a USPS tracking number by email.


  • • We care about your success and do our best to provide healthy bees. 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.

20 High-quality Mason Bee Cocoons, available to ship February - April 30, 2018. Includes FREE SHIPPING!

Spring mason bees fly in cool weather and are perfect for fruit and nut trees, berries, and virtually all spring blooming flowers. Mason bees are 100 times more effective pollinators than honey bees and mason bees can double or triple your fruit yield!

Each package contains 8 female and 12 male cocoons (nature’s natural ratio). The cocoons have been inspected and washed for pests. Although we do all we can to ensure mason bee health, sometimes bees die in hibernation.

You should only purchase bees acclimated to your region for bee raising success. Our bees are raised locally or through our BeeBuyBack program. Bees sent to you will come from a similar climate zone to help ensure the best bee health and performance.

If bees emerge during shipping, this is ok and natural for shipments between February and April. Follow the care instructions included with your bees.

Please do NOT use drilled blocks of wood or bamboo tubes. Your bees will fail within a few years due to pest buildup. Your success is important.

Bees will be sent First Class Mail and are mailed out each Monday. If you require special shipping, please email us at info@crownbees.com to make arrangements.

Additional Information


Your bees will arrive safely tucked away in their cocoons inside a small cardboard box.  Feel free to open the box to see your cocoons.  Pouring them into the palm of your hand, you should see a combination of larger cocoons (females) and smaller cocoons (males).  Cocoons must be stored under refrigeration to prevent them from waking up from their long winter's nap before spring has actually sprung.

Return the cocoons to their carton/box, or you can transfer them to a slightly larger container.  Be sure the container will allow some degree of air in/out. 

If outdoor conditions are not optimal (meaning that daytime temperatures are consistently below 50 degrees, freezing conditions at night), store your bees in the refrigerator.  The cool dark environment of your fridge is an important factor in keeping your bees in a state of hibernation.  You will also want to keep the container somewhat moist so that the cocoons do not dry out and kill the bees sleeping inside.  DO NOT SOAK the container. (Consider using our HumidiBee (cocoon humidifier) to assist with your bees’ hibernation.) 

Also, to be safe, place a cotton-ball, soaked in equal parts of white table sugar and water, inside the container with the cocoons.   If any of the bees (typically the males) hatch early, they will have a ready food supply to sustain them.  

When daytime temperatures have reached about 50-55°F, you can place the box containing your bee cocoons (with the top open) outdoors with the nesting house/material.   Place the carton or container on top of, or behind the nesting material with the top or lid open or removed.  The bees will emerge from their cocoons, crawl over the nesting material and head out into your garden, orchard, or yard.

Please note: In addition to warmer daytime temperatures, there must also be sufficient pollen available (blooming trees/shrubs/flowers) for your new bees.  Try to avoid holding your bees in hibernation past May 1st as they will begin to die in their cocoons or may emerge too weak to fly and forage.

  • Pollen, mud, clean nesting material, and correctly located/positioned houses are all key factors for successfully raising your bees. Learn more here.  
  • Please do not use wood blocks with drilled holes or bamboo tubes.  Your bees will fail within a few years due to pest buildup. 
  • Be sure to sign up, on our website, for our informative Bee-Mail.  We'll help you to be successful by telling you what to do and when to do it!

Thank you for your efforts and welcome to the fun, fascinating and beneficial world of gentle bee-keeping!
