Thanks for reaching out and for sending photos as well. It looks to be a European Hornet.
Hornets are one of a number of so-called "social wasps" found in this area. While you definitely don't want them in your house, social wasps tend to be non-confrontational and not aggressive unless a nest is disturbed or an individual feels threatened (like being swatted or caught). However, if a threat is perceived, wasps may sting, and individual wasps are capable of stinging repeatedly, unlike honey bees.
