BOTHELL, Wash., Nov. 12, 2024 /PRNewswire/ -- Bee hotels are used in gardens to provide nesting chambers for mason bees and increase pollination, but many people don't realize these bee hotels require ongoing care. Without proper maintenance, these well-meaning efforts can actually harm bee populations instead of helping them. By fall mason bees have spun a waterproof silk cocoon, making it the perfect time to safely harvest them to remove harmful predators like pollen mites, chalkbrood, Houdini fly and mono wasps. Year-round care is essential for helping bee populations thrive. Without regular upkeep, bee habitats can become a breeding ground for harmful parasites and diseases, jeopardizing the health of the bees.

Predators multiply rapidly in nesting chambers and if not cleaned then overtime your "bee hotel" will become a "predator hotel". Learn how to clean your bees in the Fall. Protecting mason bees involves understanding the various predators that threaten them. By learning more, you can take effective steps to ensure the safety and health of your mason bees.

Rent Mason Bees, the largest solitary bee provider in the country, is dedicated to educating people on the proper care and maintenance of mason bees. They partner with research teams and bee labs to study parasites and predators and educate the public on caring for these essential pollinators. Dr. Amy Murillo, an entomologist at UC Riverside who studies pollen mites, emphasizes the importance of nest hygiene: "Cleaning or replacing nests to remove mites or other parasites is important for bee health. Pollen mites can persist in nests in the inert deutonymph stage, then infest new hosts who enter the nest the following season. Sanitation or replacing the nests helps to reduce or eliminate surviving deutonymphs in the nest. This practice plays a critical role in maintaining healthy mason bee populations."

Homeowners can boost the health and habitat of mason bees by following a Year-Round Care Guide. Watch this educational video to learn how to 'Care for Mason Bees Year-Round.

Year-Round Mason Bee Care

FALL: Harvest and clean mason bee cocoons to remove them from predators and sterilize their nesting materials.
WINTER: Store clean cocoons in humidity-controlled refrigerator over winter.
SPRING: MASON BEES DO NOT STAY OUT YEAR-ROUND - Set out clean nesting material and avoid bamboo or drilled logs, they can't be opened and can get moldy. Use stacking trays or cardboard tubes.
SUMMER: Mason bees only live 6-8 weeks. At the beginning of Summer, store nesting material in a cool place to protect them from summer predators

October and November is the best time to open nesting material and remove healthy cocoons and eliminate predators that can harm your bees. Do not bring your bees indoors to clean them. Make sure to do it outside where temperatures are cold so they stay in hibernation.

WASH COCOONS: Mason bee cocoons are waterproof and need to be washed in a mild bleach solution to remove pollen mites and chalkbrood.
DRY COCOONS: Allow the cocoons to dry overnight so they don't mold during hibernation.
CANDLE COCOONS: Use a flashlight to identify and remove any non-viable cocoons that are amber or see-through.
STERILIZE NESTING MATERIAL: If you use stacking trays, use a flame to eliminate any remaining pollen mites or chalkbrood. Replace all cardboard tubes with new ones.
STORE IN WINTER HIBERNATION: Place the cleaned cocoons in a humidity-controlled container and store them in your refrigerator over the winter.

WHAT IS A SOLITARY MASON BEE?

Mason bees are nature's most productive pollinators, visiting over 2,000 blossoms daily. Their distinctive "belly-flopping" technique enables them to gather loose pollen across their bodies, resulting in an impressive 95% pollination rate compared to their honeybee cousins 5% rate. These gentle, non-stinging bees live and work independently, without producing honey or residing in hives. Their self-sufficiency makes them non-aggressive and incredibly easy to care for.
