Hello! I've had a strange situation this winter, and I'm hoping you can help me make sense of it. Three times in the past two months, I have found individual bees crawling on my living room floor. There's only ever one at a time; I place it outside, and don't see another one for a couple of weeks. We haven't had any issues with hives in our walls or near the house, and lately it's been pretty cold outside (around or a little below freezing) with the exception of a few warmer days here and there. Do you have any guesses as to where these bees might be coming from?
