I had this problem a few months ago. I found the moth larvae in some rice in my pantry. I threw out all of my rice. Then I noticed little cocoons inside of my foil and saran wrap boxes. I ended up throwing almost everything out and thoroughly cleaned everything in the pantry. So far no more moths in the house or little worms...YUCK! I don't know how this starts. This could be the problem you're having. Some moths are in the pantry, some feed off of your clothes. I believe they are different type of moths and can be hard to get rid of. Good luck!
