Add more valuable bee pollinators to your garden using Replacement Mason Bee Fiberboard Nesting Tubes for Mason Bee Shelter. Contains 94 tubes constructed of fiberboard. They are called mason bees, because they work with mud to build and seal their nests. As pollinators, mason bees are attracted to flowering plants, such as vegetables, fruit trees & bushes, flowering annuals, perennials, and vine plants. Their work in the spring can determine the volume of fruit or vegetables that will be available to harvest. Mount the house (sold separately) to a post or wall, ideally near a source of mud. The fiberboard nesting tubes should be replaced each spring after Mason Bees have emerged from their nests or early spring if using an emergence box for last year's occupied tubes.
