SUMMER Leafcutter Bees available May—August

  • • Summer bees require temperatures of 75°F (24°C) or warmer AND sufficient sources of pollen/nectar for best performance.
  • • We incubate your summer bees so they arrive ready for immediate placement outdoors.
  • • If you are seeking pollination for your flowering summer vegetables, consider when these plants will flower. A seedling planted in April or May may not produce flowers until June or July.
  • • Current agricultural restrictions prohibit the shipment of leafcutter bees to the state of HI, and other countries outside of the continental United States.


  • • A hot mail box can be harmful to developing or emerging bees. If you are not home during the day to retrieve your bees, consider having them shipped to your workplace.
  • • Select the Monday when you would like your bees shipped, allowing 1-5 days for delivery. When the bees ship, you will receive a USPS tracking number by email.


  • • We care about your success and do our best to provide healthy bees. While most customers successfully raise gentle bees, it is important to understand that bees are wild insects and may not nest in your yard, may be eaten by birds, and may not emerge from their cocoons. We cannot guarantee survival, pollination of crops, or reproduction of bees.
  • • These bees are gentle, typically non-aggressive and rarely sting, While there have been no known reported cases of anaphylactic shock in association with these bees, the use and handling of solitary bees may result in allergic reaction for some users.
  • • Please consider signing up for BeeMail, our monthly newsletter, designed to provide tips and reminders to help ensure success.



Summer leafcutter bees are super pollinators of tomatoes, peppers, squash, melons, and peas - just about any flower. Gentle solitary bees who only fly about 300 feet daily as they forage for nectar and pollen. Easy to raise bees who prefer 6mm sized holes and use soft pliable leaves like those of rose, hosta, lilac, and pea to build their protective leafy cocoons.

You can reuse your spring mason bee house to raise summer leafcutter bees. Just place the summer leafcutter nesting tray into the house and add leafcutter cocoons! Or add the kit to your own bee house.

Apply InvitaBee Spray for Leafcutter bees on the front of nesting tray, wait a few moments to dry.

Open the LeafGuardian bag of leafcutter cocoons and place on top of nesting tray or in the attic of bee house. Keep cocoons out of direct sunlight.

In the early fall, when leafcutter bee activity stops, remove filled nesting tray and store in the BeeGuard Bag with nesting holes facing up. Cinch the bag closed and store in your unheated garage or shed over the winter.
