Hi. I have a friend who needs help. She has a Butterfly house that bumblebees (big ones) have moved into and seem to be taking over. The two narrow slots in front have what looks like some kind of nesting material hanging out of them. I don't have a picture, but when we look inside the house there are at least 10 bumblebees. If the butterfly house were not quite so close to her back door, it wouldn't be such a concern.

We don't want to harm the bees. How do we politely tell these bees to buzz off??

Thanks!
