It's time to return your bee blocks

Now is the time to return your mason bee and leafcutter bee blocks. Next month, we will be cleaning the cocooned bees that were made in your backyard and their nesting blocks. The cleaning process is necessary to remove natural pests, parasites and pathogens that may have found their way to your bee blocks during the spring and summer. During fall cleaning, we also prepare the bees for winter hibernation. It is imperative that all rented blocks are returned this month so that we can properly care for these beloved bees and return the next generation of healthy bees to you next year!

If you purchased a kit shipped to your home or opted in to 1-way return shipping, then simply use the return shipping label we provided and drop off the box containing your bee kit(s) at your nearest United States Postal Service office. 

If you planned to return in person, we are offering several drop off sites for no-contact return, for your safety and convenience. A Rent Mason Bees branded tote will be located at each drop off site to serve as a waterproof, temporary holding container for the bee blocks until we pick them up. Drop boxes will be available from September 12th-20th during business hours of each respective business. A list of drop off locations can be found at the bottom of this page. Please practice safe social distancing.

Things to keep in mind when returning bee kits:

  • Do not cut straps or remove cardboard from the nesting block(s). The straps keep the bees safe and snug inside of the nest block, and the cardboard has a barcode that is linked to your information and allows us to check your kit back in. 
  • Return the nesting block with the holes facing up during transport or in the drop boxes.
  • If you are committed to hosting bees again next year, feel free to hold on to the outer black house to reuse. This will save you $5 on your rental next year and help us conserve storage space!
  • To secure the nesting block(s) inside the mailing box, you can use bubble wrap or crumpled newspaper. By this time of year, the mason and leafcutter bees are safely secured inside their silk cocoons and leaf cells, so they they are sturdy enough to be chauffeured or sent vial mail.
  • Please return the PVC tube along with your bee nesting block, so that we can clean and reuse them next season.
Drop boxes will be available from September 12th-20th during business hours of each respective business. Please practice safe social distancing.
