Mason bees are sold as winged adults hibernating in their capsule like cocoons 


After   receiving the bees, they can be stored in the fridge between 40 degrees unless it's time to release the bees when ordered. To keep the cocoon from getting dehydrated keep a moist paper towel in a slightly opened plastic bag next to the cocoon container. An older fridge would work better as it does not have the frost-free feature newer ones have.    

  • Be careful not to get the cocoons themselves wet so they don’t get moldy or expose them to direct sunlight, it will kill them. 
  • Outside temperatures ranging from 32-55 are preferable to keep bees alive. Temperatures below 32 will freeze and kill the bees. 
  • To put a cocoon in a reed, gently push in cocoon in the reed with a q tip. For mason bees be sure to put the nipple end, the head of the bee, at the outward facing part of the reed.  
  • Be sure to put it far enough in so birds and other animals do not get to the cocoon, and only put one cocoon in each reed. Attach some chicken wire around the mason bee house to help protect the bees from birds and animals if needed. 
  • Cocoons should be placed in reeds close to expected blossom time of your crops. There must be several pollen sources before the bees are released.Early spring and summer flowers, wildflowers, and native weeds are best as are flowering fruit and native trees and bushes close to the mason bee home so that bees prosper and keep coming back. 
  • Fruit trees blossom for a short time so it is important to have a lot of other of the above vegetation for the bees 
  • DO NOT release bees if weather is bad or too cold otherwise the bees will not get to the pollen sources 
  • Bees should be released in mid-March to mid- May 
  • Place cocoon filled reed(s) in a mason bee house with fresh, empty reeds then place the house so it can be reached by the sun to hatch the bees and to keep them healthy and active but with leaves and branches above the house to protect it against rain and scorching summer suns 
  • It is best to have the house facing south east so the bees warm themselves and become active in the early morning 
  • For Californica bees: place the orange pollen covered cocoons with blue orchard cocoons. They work well pollinating together and will need a box, can, or bottle with at least a 9mm opening due to not being able to determine which end is the head like mason bees 
  • Be sure to keep a moist soil source like mud near their nest, blue orchard females build their nests in it 
  • Keep house in place until fall after the bees’ flight. DO NOT change the surroundings of the bee house after bees have hatched, disturb the nest or cover it as this will scare the bees and never return to the nest. 
  • Store nest in garage or shed when positive bees are not around the nest, making sure it is covered to protect against pests. 
  • To harvest cocoons out of nesting reeds (around the end of November) simply insert a thin knife into end of reed and twist it to break the reed in half 
  • Remove cocoons, inspect the cocoons for pests then gently clean the cocoons and put in the fridge until next spring when you repeat the process, use new nesting reeds each year to help the health, success of the bees. 


 The bees need to stay cold in order to stay healthy and hibernating, we have shipping cold packs to help keep the bees cool and dormant during shipping. These bees should be ordered during the cold fall, winter spring months and will start to come out of dormancy when exposed to temps above 55 for a prolonged time. These bees are from the intermountain region in Utah and may not be native to your area. These bees are not recommended for humid tropical climates. The bees need a lot of good bee friendly pollen sources for the bee's entire lifespan and quality house nests to survive and reproduce. We recommend having some native pollen sources from flowers, trees, bushes etc. for the bees.  For warm outside temperatures above 55 degrees we highly recommend using express mail for orders.
