Meal Moths - A Forever Thing?

I service an ethnic supermarket with an ongoing issue with Indian Meal Moth. We install some traps with lures every now and then, but would like to take care of this issue for good. I've asked them to clean all of their shelves in the store and they did (more or less). I suggested they contact their supplier because that may be the actual source, but they don't want to go this far because they have more than one supplier for their orders. What do you suggest I do next?

They breed rapidly, with females producing around 300 eggs, and the larvae are very mobile, often leaving the infested food and wandering throughout a structure to find the perfect place to pupate. All of this makes it more difficult to isolate the problem and they may be infesting a multitude of packages.
