WFBKIT Emergence Chamber Kit. Made in Canada Discontined :(

This kit makes it easy for you to clean your Bee Nests if you wish to. An Emergence Chamber is a slip-on cover that fits neatly onto your Solitary Mason Bee Nest. It allows new bees to emerge from the bee nest but not return, leaving the nest tubes empty and ready to clean. 

Instructions are enclosed with pipe cleaners to get the job done.
