bumble bee or a carpenter bee

6009  This bug has been flying around outside my bedroom window for three days now. I just want to know if it’s dangerous or not.

This is either a bumble bee or a carpenter bee; as it has been sprayed with some substance, I cannot be certain which it is. Also, I believe that this image has been posted before. Ed Saugstad, retired entomologist; Sinks Grove, WV.
