Hi Margriet – when is your best guess as to when to put out the Bee Cocoons? I have had them in my outside storage shed all winter, but with the warmer weather as of late, and not much in the way of flowering trees, etc., I hate to have the Bees emerge too early, so I have placed them in a picnic cooler with ice packs, to simulate a cooler or colder climate. Let me know what you suggest. Thanks, Andy.
Hi Andy, Yes the cooler will work in the short term. For the longer term, use a humidity cooler inside a fridge. A storage shed works until it warms up in late winter. The simplest way of storing bees is in the attic of a bee home. Bees will emerge when temperatures improve during the early spring. But with experience, if you find that bees emerge earlier than fruit tree blossoms in your garden, then refrigeration inside a humidity cooler is the way to go. Temperature inside the fridge needs to be between 2-4C. If mason bees are kept in hibernation until late April- early May, fridge temperature needs to be decreased to 1-2C. Dr Margriet.
