7 Reusable wood trays made of Red Alder strapped together to create 48 nesting holes.
Wood is the natural habitat for Mason bees which provides insulation and moisture control.
The front of the trays are burnt to provide visual clues to help the bee identify which hole it is nesting in.
Wood retains scents left from nesting Mason bees which acts as an attractant the following year.
Nesting holes are 8mm which is the mason bees preferred size.
Easy to open for harvesting your bees in the winter.
