Mason bees, known for their exceptional pollination capabilities, play a vital role in ecosystems. Here's an in-depth look at their habitat, predators, and essential care tips:

Habitat of Mason Bees:

  • Mason bees utilize pre-existing nesting sites such as insect holes, hollow stems, and woodpecker holes.
  • Increasingly, gardeners are installing bee hotels to attract mason bees, but improper maintenance may pose threats to mason bee populations.

Rise of Mason Bee Predators:

  • Predators and parasites pose a significant threat to mason bee populations, with invasive parasites such as Houdini flies and pollen mites becoming prevalent.
  • Annual cleaning and sterilization of nesting material are crucial to prevent infestations and safeguard mason bee populations.

Care Tips for Mason Bees:

  1. Provide Clean Nesting Material: Replace nesting material every spring to prevent the buildup of pollen mites and chalkbrood.
  2. Use Easily Opened Nesting Material: Avoid materials like bamboo or drilled logs that encourage predator infestations. Opt for stacking trays or cardboard tubes.
  3. Remove Nesting Material Annually: Mason bees have a short lifespan, requiring the removal of nesting material at the end of spring to prevent summer predator infiltration.
