Spiders and Leafcutter Bees: Maintenance Tips

To ensure a harmonious environment for your Leafcutter Bees, we recommend regularly brushing away spiderwebs and cobwebs from your bee home. Here are some key tips for managing spiders without resorting to chemicals:

  1. Regular Cleaning: Periodically inspect and clean your bee home, removing any spiderwebs or cobwebs that may accumulate. This simple maintenance routine helps create a spider-free zone for your Leafcutter Bees.

  2. Avoid Chemicals: Refrain from using chemical pesticides or insecticides around your bee home. These substances can be harmful to both spiders and bees, disrupting the delicate balance of your garden ecosystem.

  3. Natural Predation Dynamics: Spiders catch very few bees, and any bees that may get caught are often males, which are expendable to the colony. Female Leafcutters, often possess the ability to extricate themselves from cobwebs.

By adopting these practices, you can foster a safe and spider-friendly environment for your Leafcutter Bees. Remember, maintaining a natural balance in your garden contributes to the overall well-being of your pollinators and the ecosystem. 

Ants and Earwigs

 Addressing ants and earwigs around your Leafcutter Bee home is essential for maintaining an optimal environment for the bees. Here are some tips to manage both pests:

  1. Elevate and Use Barriers:

    • Raise the Leafcutter Bee home and employ physical barriers like ant moats or  petroleum jelly, can be applied to the support structures of the bee discourage both ants and earwigs from accessing the nesting tunnels or cocoons.
  2. Apply Natural Repellents:

    • Utilize natural repellents such as cinnamon, citrus peels, or coffee grounds around the base of the bee home to deter both ants and earwigs without harming the bees.
  3. Keep the Area Clean:

    • Ensure the area around the bee home is free of debris and potential food sources. A clean environment discourages pests from nesting nearby.
  4. Inspect for Trails:

    • Regularly inspect for ant and earwig trails. Disrupt these trails to prevent the establishment of routes leading to the nesting site.

    • These may kill the ants/earwigs but they will also be highly likely to kill your bees too!
  6. Regular Maintenance and Cleaning:

    • Conduct regular maintenance on the bee home, checking for signs of ant and earwig activity. Promptly address any issues to prevent them from escalating.
  7. Relocate if Necessary:

    • If ant and earwig problems persist, consider relocating the bee home to an area less prone to these pests.
  8. Monitor and Adjust Strategies:

    • Continuously monitor the effectiveness of your pest management strategies. Be open to adjusting methods if one proves ineffective against either ants or earwigs.

By implementing a comprehensive approach to pest management, you can create a secure environment for your Leafcutter Bees, promoting a successful nesting season while addressing challenges posed by ants and earwigs.

The measure of success with Leafcutter Bee Keeping - Have your Leafcutter Bee been successful?

The ultimate measure of success in keeping Leafcutter Bees is the emergence of these industrious pollinators from their cocoons. Once your Leafcutter Bees have successfully emerged, it signifies that your cocoons have effectively supported their growth and development throughout the season. The males will gracefully hover around the beehome, patiently awaiting the emergence of the females, which typically occurs up to two weeks later. After mating, the males fulfill their natural life cycle, gracefully departing the scene. The newly mated females, now equipped to pollinate, embark on their mission to enhance your garden's biodiversity. Importantly, Leafcutter Bees exhibit diverse nesting preferences, and whether they choose the provided beehome or opt for natural cavities, hollow plant stems, or other garden features, it is entirely normal. The key takeaway is that the success of your Leafcutter Bees is not contingent on their nesting location. Introducing these bees to your garden contributes to the proliferation of pollinators, enhancing pollination and fostering the growth of New Zealand's Leafcutter Bee population. While we offer an optimal nesting environment with suitable cavities and weather protection, the decision of where to nest ultimately lies with the bees, as we respect the inherent unpredictability and autonomy of nature in this process.


Melittobia and Leafcutter Bees in New Zealand: Management Tips

In New Zealand, we are fortunate to have one of the cleanest and pest-free populations of Leafcutter Bees globally. However, the primary pest of concern for Leafcutter Bees in NZ is the parasitoid Melittobia. Here are some insights and tips for managing this potential threat:

  1. Identification of Melittobia Presence: Adult female Melittobia leave very small holes in the leaf of bee cells, indicating that they have chewed into the cells and potentially laid eggs. Detecting these holes signals the presence of Melittobia in the environment.

  2. Late March to Early April Vigilance: Bee activity decreases around late March to early April, and some nesting holes may be capped if Leafcutter Bees have chosen your bee home. This is a critical time to monitor for signs of Melittobia activity.

  3. Damage Control through Refrigeration: To mitigate the impact of Melittobia, promptly place your Leafcutter Bee cocoons into the fridge. The prepupae within the cocoons can withstand temperatures well below freezing, ensuring that all Melittobia parasitoid adults, eggs, and larvae perish.

  4. Winter Storage Recommendations: To prevent Melittobia damage over the winter period, store your Leafcutter Bee cocoons in the fridge at temperatures around 2-5°C. This practice minimizes the risk of issues with the parasitoid, safeguarding the health of your bee population.

By following these measures and maintaining a vigilant approach during the critical late-season period, you can effectively protect your Leafcutter Bees from the potential impact of Melittobia. This proactive approach ensures a thriving and healthy bee population for the seasons to come.
