Providing a safe place for solitary bees to live and breed. Bee hotels are made from untreated (so as not drive the bees away with toxic fumes) pine with multiple, different sized holes drilled into one face. The size of the holes have been informed through research and experimentation and each size is perfectly suited to specific species of solitary bees. The holes mimic the natural holes the solitary bees would find in nature. Usually these holes are made by other insects in dead wood, as most solitary bees (carpenter bees are an exception) cannot create their own holes. The holes offer a safe place for solitary bees to rest and breed.
