Mason Bee Guard Tubes - Bundle of 50
Click To Enlarge

Guard tubes are very important for a healthy colony that is free of parasitic wasps.  The little wasps will make holes in your paper liners if you do not have a guard tube to protect the thin walled liners.  The wasps will lay their eggs within the cocoon of a mason bee and the wasps will invade your mason bee cocoons.

These 8mm tubes are the perfect size for your mason bee needs.  They are constructed of 100% recycled material and can be reused each year.
