Raising Leafcutter Bees

Leafcutter bees (Megachile spp.) are gentle, solitary, native pollinators that are highly effective—often more so than honeybees—for many garden plants, especially legumes, fruits, and vegetables. Unlike carpenter bees, they do not damage structures, making them ideal for backyard pollinator support. Here’s how to raise them responsibly and successfully.

🌿 Why Raise Leafcutter Bees?

• Superb pollinators: One leafcutter bee can do the work of 10–20 honeybees.

• Non-aggressive: They rarely sting (only if trapped or squeezed).

• Easy to host: Require simple nesting materials—no hives or complex equipment.

• No honey production, but excellent for biodiversity and food gardens.

🏡 How to Raise Leafcutter Bees

1. Provide Nesting Tubes

• Use paper straws, cardboard tubes, or wooden nesting blocks with 5/16" (8 mm) diameter holes, 4–6 inches deep.

• Avoid plastic or bamboo (traps moisture/mold).

• Place tubes in a protected bee house facing east or southeast (morning sun, sheltered from wind/rain).

2. Install the Bee House

• Mount 3–6 feet off the ground on a fence, post, or wall.

• Ensure it’s stable and dry—moisture is the #1 cause of nest failure.

3. Time It Right

• Leafcutter bees are active in late spring to summer (varies by region).

• Install nesting materials just before local bloom time (e.g., when alfalfa or roses start flowering).

4. Provide Nesting Materials

• They cut neat circles from soft-leaved plants like:

  • Roses

  • Lilac

  • Virginia creeper

  • Clover

• Don’t use pesticides—they’ll contaminate leaves and harm larvae.

5. Ensure Pollen Sources

• Plant diverse summer-blooming flowers: sunflowers, cosmos, lavender, peas, beans, berries.

• Aim for continuous bloom from June–August.

6. Manage & Protect Nests

• In fall, remove filled nesting tubes and store them in a cool, dry, ventilated container (e.g., mesh bag in a shed or garage).

• Protect from parasites (e.g., chalkbrood) and predators (wasps, birds).

• Do not leave nests outside all winter—they’re vulnerable to moisture and pests.

7. Release in Spring

• In late spring (when temps consistently reach 70°F/21°C), place nests back in the bee house.

• Emerging adults will mate, forage, and begin nesting within days.

⚠️ Common Mistakes to Avoid

• Using bamboo reeds (can’t be cleaned; harbors disease).

• Placing houses in full shade or direct western sun.

• Overcrowding—space out multiple bee houses.

• Disturbing nests during active season (June–Aug).

You’re not “farming” them—you’re providing habitat. Let nature do the work! With minimal effort, you’ll boost pollination, support native species, and enjoy watching these fascinating bees in action.
