Additional Information

  1. Your mason bee house should ideally be placed in a location that receives sunshine earlier (as opposed to later) in the day to encourage bees to rise early and get to work.  Place BeeTubes, open end facing outward, in your bee house.  Nature tends to be a bit random, so consider adding a few twigs or sticks between tubes to break up the pattern of the tubes in your bee house.  Additionally, push some tubes in deeper than others to create a "3-D" look and feel.  This spacial differentiation will help nesting females to quickly and easily locate her nesting tube. 
  2. Consider the use of InvitaBee™ attractant sheets to add the smell of mason bees to your nesting tubes.  
  3. Please attempt to keep your BeeTubes out of direct rain.  Crown Bees houses are designed with roofs to overhang beyond the end of the tubes.
  4. When spring mason bee activity has ceased (typically by early June) remove tubes from bee house and store mud end up, out of direct sunlight, allowing larvae to develop and mature.  Consider a BeeGuardian™ fine mesh bag for storage of BeeTubes over the summer helping to protect developing bees from pests such as ants, beetles and wasps.  Exposure to average air temperatures typical for your region will help bees to develop at the appropriate rate.
  5. In October, determine which tubes are empty and which contain mud and larvae by first examining each tube.  If mud is obviously visible at the end of a tube, set it aside for harvesting.  For tubes where mud is not so obvious, hold the tube up towards a light source and peer through the open end of the straw.  If light can be seen through the tube, the tube is empty and can be set aside for reuse next year.
  6. BeeTubes can be opened easily by making a nick or tear  in the open end of the tube with a scissor or razor blade and then continuing to tear or unravel the tube, exposing any cocoons.  Cocoons can be easily extracted from the unravelled tubes.
  7. Questions about harvesting specifics?  Consult our harvesting section for more information.

Please be reminded of the importance of NOT leaving your nesting tubes out in your bee house all season.  Doing so only increases the risk of attack by pests and predators thereby reducing the number healthy cocoons at harvest.  The simple act of protecting your tubes may be rewarded by a bountiful harvest!
