I cannot tell if they are bees or wasps (they are thin and have yellow and black striped thoraxes), but they are entering into an outside window casing by crawling into tiny holes that are in the casing. This is on my front porch. There are only four holes altogether. How can I get rid of the critters? Would it help to either plug the holes or seal them with duct tape? I need some ideas - this started only recently when I noticed a bee buzzing just outside the living room window, then found it crawling into one of the tiny holes. Advice, please? Thanks!
