    How to Return Bee Blocks 1

    It’s September & Time to Mail Back Your Mason and Leafcutter Nesting Blocks!

    This spring and summer buzzed by quickly, and we want to extend a big thank you to all of you for hosting solitary bees this year and creating a safe and nurturing habitat for our pollinators!

    Watch our steps to sending back your blocks:

    Throughout the month of September, please remember to mail back your nesting blocks.

    WHAT TO SEND US:

    • Keep your black house to refill next season.
    • Send back your nesting blocks.
    • If you still have your white PVC tube and the bags of ice, feel free to include those as well—we’ll recycle them. YOU DO NOT NEED TO PUT YOUR BEES ON ICE TO SEND BACK. 
    • Pack them with newspaper or recycled shipping bubbles so they don’t jostle around during shipping.
    • Don’t forget to include your first and last name inside the box.

    Avoid the Late Processing Fee: Mason blocks returned after September will be charged a late fee, since they must be cleaned by hand.
