How to react to unexpected weather changes
Bees are accustomed to temperature swings, including freezing temperatures at night.
Female bees will wait in their nesting holes until the bad weather passes. The male bees wait out bad weather on plants near the bee house.
Spring Mason Bees: For bees waiting to be released, hold them in your refrigerator until the poor weather has passed or daytime temperatures return near 55F(13C). One day of cold or stormy weather will not harm mason bees.
Summer Leafcutter Bees: For bees waiting to be released, keep the leafcutter bees inside and place the bees outside the morning after the storm passes. Leafcutter bees fly best in temperatures above 75F(24C) but can fly in cooler weather if they must.
