My beard wasn’t so lucky.
We got a cold blast of Canadian rain and it soaked the beard of bees; probably 2000 bees. A bunch fell off the hive, into the grass and died. The rest were like wet mutts that were barely alive. I scooped them into a oven pan and put them in the oven for about 15 minutes. That dried them off and brought them back to life.
Word to the wise, don’t let your hive get so warm that they stay outside in the freezing rain. Make whatever design changes you need (like a top vent).
If I get time, I might start a new thread with photos of how to bake bees in the oven for 15 minutes to bring them back to life.
