Female mason bees build the walls of their nesting chambers out of mud or other "masonry" products to give each developing bee its own room in the nesting chamber. Female mason bees will then secure the nesting chamber with a thick mud end-cap to protect their offspring from predators until they emerge to pollinate the following spring.
Because mud is vital for mason bee reproduction, females will not nest if they do not have a reliable source nearby (within 25 sq. ft.). However, not just any mud will do! Mason bees prefer to use mud with a high clay content - or that is the consistency of modeling clay. Read more here.
- 8 oz of dry clay
- 100% recycled, 90% post-consumer recycled content paper bag.
- Spring mason bees use moist clay-rich mud to protect each nesting chamber and female mason bees prefer clay-rich mud, not just clay or wet dirt. Our Mason Bee Mud Mix is just the right texture that mason bees are looking for.
- You can ensure that your yard provides a clay-rich mud source. Within about 25 feet of your bee house, use a trowel or shovel to open a wedge in your soil and add water to check for consistency. If your soil does not stick together when wet and pinched, add Mason Bee Mud Mix to the side of the wedge in the ground. Mason bees like to gather mud from the vertical wall and the groundwater will help keep your mud mix moist.
