A tip if you have an annoying fly in your house that's hard to swat. Turn off all the lights except the bathroom. In a few minutes it'll fly in. Close the door and it's mano-a-mano.
Works well with mosquitoes too. I just let them do whatever they want in the bathroom once the door is closed.
However I would admit that switching lights on at 3AM and deliberately opening all the doors for the light to be seen is not something my family appreciate. But, at least, I’m their hero.
