Thanks for reaching out with your question. Our plant and soil science expert sent this response:

"This appears to be a boxelder bug, a common home invader in the fall. They cause no issues other than being a nuisance. They come in when the cold weather sets in in the fall. I am including a link to some info on this nuisance pest. I would not recommend using any pesticides, but try the different methods suggested, such as caulking cracks, fixing screens, vacuuming, removing boxelder (also ash and maple) trees near the house, etc."
