Mason Bee Cocoon Storage

The End of the pollination season. Harvest your Cocoons and store them in a humidifier and chilled humidity-controlled environment.

When your bees have stopped all activity, do not move them for 30 days or you will dislodge the fragile eggs.
After 30 days usually around the End of July move them into your garage or shed for storage.

In October or November, if you are working on Mason Bees; and February if Leafcutter bees, take your nest block apart with a potato peeler and scoop the cocoons and dirt out of the grooves of nesting block.

Brush out the nesting block and spray with Mason bee attractant. Attractants act as prep for next season and as an antiseptic to kill mold and mildew.

Wash the cocoons, with a spray of water, while they are in a strainer until the water runs clear. Set cocoons on a paper towel and let them dry. When dry, put them back in the Humidifier bee-safe till next spring.

Mason bee cocoons overwintered in a 34-38F (1-3C) controlled environment (your refrigerator) consume their stored fats much slower than in fluctuating outdoor temperatures and emerge stronger and ready to go to work, in the spring. Plus, you can hold them longer in your refrigerator, so you can control your release dates.

The only problem is that your refrigerator has a very low humidity around 10-20% and your cocoons will dehydrate, dry up and your bees will die. To solve that problem. Store them in our $11.45 Humidifier, which you can use year after year.
