Ok, so I have recommended using Pantry Moth traps in combination with Aunt Norma's Pantry Moth Spray, and I find the combination to be the most effective way to handle the problem. The Pantry moth spray will kill eggs and larvae and keep the moths from going back into your pantry, but once you have these stupid things it seems like it is impossible to get every single eggs, moth and larvae in one swoop. This is becuse they can hide and lay eggs just about anywhere, and also because once they hatch into adult moths they can fly into other parts of the house. You have likely seen them on the ceiling and in other rooms besides the kitchen.
Pantry Moth TRAPS have a pheremone lure that attracts the males, and then they get stuck in the sticky glue tape inside the trap. You can see their effectiveness by checking the moth carcasses every day in the glue. YUCK! They don't kill eggs or larvae, or deter moths from the areas like the Moth Spray does, but they sure are an effective back-up that can kill the moths that you missed or that have hatched after you have cleaned. This is why using them AFTER the moth spray is so effective- it basically just speeds up the elimination process. If you use the moth traps alone, they still work, but it takes a lot longer to get the numbers down.
Something that I have just learned though, is that if you get over-zealous and put out several pantry moth traps, the horny little buggers get confused and can't follow the scent to the trap, so if you several have pantry moth traps out that don't seem to be working, try removing all traps but one and see if that helps.
