I have an old laptop that does that and the keys are very distracting whenever I hold it in tablet mode. I find myself holding it awkwardly on one side to avoid them, even though I know they’re disabled. It is still a nice feature though, I like being able to transition a laptop to portrait mode sometimes.
Hard to tell from the picture but it may be a mud dauber, which is not a very aggressive wasp (to humans) and is useful for controlling spider populations. if they’re getting up into your ceiling near the light fixture, blocking it off may prevent it from trying to nest there. if it’s building on the fixture itself, knocking down the nest might convince it to relocate to a safer area. I’ve never had a mud dauber sting me even while knocking down nests, but I would still wait until it’s off gathering mud to make an attempt on the nest.
