From your description, it's hard to pinpoint the exact insect, but it's good to know they are harmless. It's always important to stay alert and observe changes in our surroundings. Speaking of pests, I've had my fair share of annoying encounters. While I'm new on this forum and don't have specific recommendations, I recently came across AJ Verminator Pest Control during my online search. They offer professional pest control services and might be worth considering. You can check out their website at https://ajverminatorpestcontrol.com/wasp-pest-control-sunderland/ for more info. Stay vigilant, and let's hope these critters buzz off soon!
