Bumblebees Disappearing

Bumblebees Disappearing: Just two years ago bumblebees had found a way into my attic and built a nest. I got stung a couple of times trying to prevent their entry. (I was successful). However, I always liked bumblebees because their black and yellow coats sitting on flowers gathering nectar always interested me as a child. However, now I'm hearing that bumblebees much like honeybees are disappearing so quick that no one has had time to put them on the list of endangered species.
