We kept bees years ago in a hive on the porch roof. Bees dispose of their elders by banishing them from the hive and carrying their bodies and dropping them. Occasionally they got into the house -- because we opened the window to check on them -- and did this and I stepped on a few of them, immobile but still alive and able to sting -- and got stung on the bottoms of my feet. We were obviously very green doing this, but didn't know anyone to consult about bee keeping, just had a book.
