They incorporate reeds, bamboo or other materials to create a bundle of horizontal tubes, open at one end, closed at the other.
[4] These nested tubes require maintenance and cleanliness as bees in hotel are more susceptible to disease, such as the spread of chalkbrood.
[7] Approximately 30% of the 5,000 native bee species in North America build nests in tunnels or cavities situated above ground.
Bees, unlike wasps, favour hotels that receive direct (especially morning) sunlight, and that are closer to the ground.
Both Cory Sheffield and Laurence Packer encouraged creation of bee hotels, despite the issues identified in the Toronto study.
