I have the cocoons outside, but no bees have emerged yet

Bee cocoons should not be placed in direct sunlight. Too much exposure to hot, direct sunlight can harm or kill a bee cocoon. Our instructions are to place the bee cocoons inside of the bee house, out of direct sunlight.

  • MASON BEES: Have patience. If your trees, berries, flowers, or vegetables are in bloom and daytime highs are around 53F, then bring a portion of bee cocoons inside to your warm house. Keep them in a HumidiBee container overnight and the warm temperatures indoors will cue them to begin emergence. Cool the container in your refrigerator for about 5 minutes to slow the bees down for easier handling. Now, release them on top of or behind your nesting material or somewhere within your bee house. Or, be patient and let the bees come out on their own outdoors.
  • LEAFCUTTER BEES: Have patience. Cold weather can slow your bees’ development, or it may be possible that you have dehydrated them if temperatures were too hot. Try carefully opening a leafy cocoon and see what the bee looks like inside. If you see a white larva, then it hasn't developed enough and needs more time. If the larva or bee is dried up, then it dehydrated.
