response: Are they bees or maybe a type of social wasp? If you can snap a clear photo of the insect we will probably be able to tell. You can attach them to this response and just make sure the file size is at least 1MB so we can zoom in and see enough details to ID. We would assume that it is a type of wasp. You can use a pesticide sprayed into the hole if you are comfortable do so but there isn't a way to deter them or encourage them to leave other wise. If you are concerned about safety or getting stung you should hire a professional pest control company to evaluate and remove. If we can confirm it is a wasp and not a bee then they will most likely die at the end of the season with a killing frost and if you have a different entrance to use until then, you can avoid the area.  Emily

response: They look like wasps to me. Here’s two photos but unfortunately they aren’t as big as you need to zoom in. On Wednesday, September 4, 2024, Ask Extension <<personal data hidden>> wrote:-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-Dear Lindsey, here's the response to your question: Are they bees or maybe a type of social wasp?
