Mason bees and other species of wild bees are excellent pollinators for the garden, especially for greenhouse crops, orchards and fields. Bees of this species are not aggressive, so they are safe for everyone, even the smallest garden users. A beautiful nature observation for children and a biology lesson due to the interesting behavior of individual bees. Bees hatch from each cocoon in spring. They pollinate all crops within a radius of up to 300 m from the nest. I only use natural reed grass for breeding. We have been involved in court training for many years, we have a lot of experience, we invite you to ask any questions, we will answer all of them.After purchase, the cocoons must be stored in a cool place to keep them in good condition in spring, so if you do not have a cool place, choose the shipping option in January, you will have a guarantee of good quality cocoons.
