When it happened to me, I got rid of anything that could have been contaminated. From that point on, I have put all grains, legumes, whatever into airtight plastic containers or Mason jars. I have used the bait stations, though I don't anymore. They won't kill all the moths, but at least you'll know you have moths if you see one or more trapped there. I believe that the bait stations are only good in trapping the male moths, as the trap I used had a little rubber bit that was said to be infused with female pheremone, which attracts the males.
Surprisingly, the moths themselves don't eat; they are specifically designed to breed. It's the larval stage that eats and eats and eats...
The only way I got rid of them was the throw out ALL dried items that they got into. This includes dried spices - so I don't really think the bay leaves will work - also potpourri, birdseed, dry pet food, dried flower arrangements - ANYTHING dried and organic. I even found them in one of those cracked corn pillows that you microwave and put on a sore neck or knee etc. I consulted with the University of Connecticut Dept. of Agriculture to find out what they were and followed their advice to dispose of everything and start over, storing everything in tupperware-type containers. Now they make pantry-moth traps or bait, I think, but I have never used them. I would be interested to know if they are effective.
