Imo the easiest option: fly screens everywhere. Especially in bedroom and keep this door closed so they won’t get in (in case they come through other doors)

I no longer have issues with them and if I ever see one, I just use my electric fly swatter. I also can’t sleep when there’s one in the room.

Fly screens are totally worth it. Self made might be cheaper, but I’m not cerrain since I didn’t do them myself.
