have any of you had maggots on your kitchen ceiling? my kitchen it's really clean and I been finding this and had to throw away my rice cause I found it in it too. I was doing research and they say it's called pantry moths infestation and they come from outside and find their way to get in all pasta, dry grains like cereal boxes etc. I'm going to clean an throw away a lot of stuff but wondering what else to do to prevent them from coming.
