Ugh! Poor Bees

I guess there was a swarm at my work on Monday, which was my day off. They called an exterminator and killed off the whole hive... my stomach hurts just thinking about it. I let them know that I can pick up any bees if they ever come back. That I would gladly take time off of work to move them off the property. ... I guess it was a large swarm.. and now it's all dead. =(
