Bee-Safe Nesting Materials for Mason & Leafcutter Bees

Nesting materials play a critical role in the health of Mason and Leafcutter bees. Tube size, length, and breathability affect how bees develop, how many females emerge, and how well future generations are protected from pests and disease.

At Crown Bees, we offer bee-safe, replaceable nesting materials designed to support healthy development and long-term success for native bees.
