Spotting a mason bee covered in pollen mites can be a concerning sight for any gardener or bee enthusiast. These tiny parasites can cling to your bees, impacting their health and reducing their ability to pollinate effectively. While mason bees are essential for pollinating fruit trees and other plants, infestations of mites can severely affect their performance and overall population.
Let's explore how these mites affect mason bees and what you can do to keep your pollinators safe and thriving.
What Are Pollen Mites?
Pollen mites are tiny, parasitic pests that feed on the pollen stores intended for the mason bee larvae. They often attach themselves to adult bees, hitching a ride to new nesting sites and flowers. While they don’t directly harm adult bees, they can significantly reduce the pollen available for larvae, leading to malnutrition or death.
This infestation starts when mites invade mason bee nesting blocks, particularly in humid environments. Left unchecked, these mites can decimate a population of mason bees, spreading from one nest to another as bees carry them on their bodies.
The Impact of Pollen Mites on Mason Bees
A bee covered in pollen mites will likely struggle to fly or forage properly. While adult mason bees are resilient, carrying mites across their bodies can slow them down and reduce their effectiveness in pollination. Worse yet, if a bee brings mites into a nesting cavity, the parasites can invade and deplete the pollen stores meant for the developing larvae. Over time, the larvae starve, and the infestation spreads to the next generation.
This poses a significant threat to the life cycle of bees. Mites interfere with reproduction by attaching to newly emerged bees, preventing them from collecting enough pollen to feed their young. The long-term effect of this is fewer bees emerging each season, directly impacting your garden’s pollination success.
How to Prevent and Control Pollen Mite Infestations
Protecting your mason bees from pollen mites starts with proper care of their nesting environment. Here are some effective methods for controlling mites:
- Regular Cleaning: At the end of the pollination season, remove and clean your bee nesting blocks. Consider using bee trap attractants to divert mites from your bee blocks. If you're using paper tubes or removable trays, discard or disinfect them to prevent mites from returning the following season.
- Washing Cocoons: In the fall, harvest the mason bee cocoons and wash them in cool water. Rinse off any visible mites and consider using a mild bleach solution to disinfect the cocoons. After drying them, store the cocoons in a cool, dry place until spring. This process helps remove the majority of mites clinging to the cocoons, reducing the chance of re-infestation.
- Rotate Nesting Blocks: Avoid reusing the same nesting blocks year after year without cleaning. Mites can accumulate and spread within a block, so it’s crucial to regularly replace or clean your blocks. Some experts suggest using a metal screen to roll the cocoons and remove any lingering mites.
The Importance of Healthy Pollinators
Mason bees are among the most effective pollinators, often outperforming honeybees in certain environments. Ensuring their health by controlling mite infestations contributes to the overall benefits of bees for agriculture and biodiversity. Mites not only reduce the bee population but also impact the ability of these bees to pollinate plants effectively. By taking preventative measures, you can help protect these crucial pollinators and maintain a thriving garden or farm.

Frequently Asked Questions About Hairy Bees & Pollination
Q1. What are pollen mites, and how do they affect mason bees?
Pollen mites are parasitic pests that feed on the pollen meant for mason bee larvae. While they don’t harm adult bees directly, they can severely impact the bee population by depleting the pollen necessary for larvae to develop.
Q2. How can I tell if my mason bees are infested with pollen mites?
You may notice small yellow, white, or red mites clinging to the bees’ bodies or within the nesting tubes. Bees infested with mites may have trouble flying or foraging properly.
Q3. How do I clean mason bee cocoons to remove mites?
Gently wash the cocoons in cool water, and consider using a mild bleach solution for disinfection. After washing, let the cocoons dry completely before storing them for the winter.
Q4. Can mites kill mason bee larvae?
Yes, mites can starve the larvae by consuming their pollen stores, leading to malnutrition or death. Infestations can significantly reduce the bee population over time.
You should clean the bee blocks at least once a year, typically in the fall after the bees have completed their life cycle. Regular cleaning helps prevent the spread of mites and other parasites.
