Things to Know About Hatching Your Bees
Throughout the spring our most common question from customers is “When will my bees hatch?”. As with most parts of nature the answer to this question is quite variable. We know that you are anxiously awaiting the emergence of your bees and are excited to see them fly. Below are some guidelines to help you understand the process and to get the most enjoyment possible from your purchase.
If you purchased your Backyard Pollinator nesting block or Bee Barn from our online shop the bee larvae will be contained within the nesting tunnels. If you order the nesting block/Bee Barn in the early spring months (March - May) it can be stored in a cool place until temperatures are in the 20’s Celcius each day. If you want to bring your nesting block out of storage in early May and keep it in your warm house, this will help the larvae to come out of dormancy more quickly.
A Backyard Pollinator Bee Barn purchased from a retail location (such as Peavey Mart) will have an empty nesting block and a code on the bottom of the barn which enables you to receive a 25g bag of leafcutter bee cocoons in the mail. If you order the cocoons in the early spring months (March - May) the bag can be stored in a cool place until temperatures are in the 20’s Celcius each day. If you bring your bag of cocoons out of storage in early May and keep it in your warm house, this will help the larvae to come out of dormancy more quickly.
LEAFCUTTER BEE COCOONS NEED AN EXTENDED PERIOD OF WARM WEATHER TO FULLY DEVELOP & HATCH. Much patience is required!
When we hatch our bees for the fields it takes 23 days at 30C. If the temperature is less than 30C it will take longer, sometimes much longer. In your backyard (particularly if started in the month of May) this process can take 4-6 weeks. On the Canadian Prairies it is usually best to not even put your nesting block outside until very late May / early June and to not expect hatching bees until the first or second week of July.
LEAFCUTTER BEES ARE A SUMMER POLLINATOR. They will likely not hatch in time to pollinate your fruit trees but can be of benefit to summer flowering plants. And once hatched, these bees need warm weather to emerge from their nesting block and fly (+25C is their favorite temperature), so the warm months of July and August are the best time to observe the activity of these bees.
