I live in a relatively new house in Ibaraki. There is what I am assuming is a cockroach or some other kind of bug flying bug trapped inside the light cover of my shower. I know they can squeeze in really tight spaces but looking at the light cover it doesn’t seem possible, could it have come in from the fixture inside??

Do I have to deal with this now or can I just leave the light on all night and deal with it tomorrow? Do I need spray? I don’t have much experience with roaches…I don’t do well with large flying bugs 😭
