Pantry moth prevention

A few years ago, I had a batch of dried great northern beans that were infested with moths. From there, they spread throughout my kitchen and pantry, getting inside tubs of flour, opened boxes of crackers, other bags of beans, rice, etc. They even reduced an opened bag of slivered almonds to a dark brown goo. Since then, I've deep cleaned my kitchen and pantry and keep pheromone in my kitchen and pantry The problem is that I still have the moths. Even though I swap the traps out every few months, they are always filling up. I don't know where they are breeding, or what they are eating. Is there a way to eliminate them, short of taking my kitchen and pantry down to the studs and rebuilding?

I too want to know the answer to this question!

My suggestion would be to put everything that could have moths into the freezer.  At least for a day or two, then put into sealed containers.

Basically, take everything out of the kitchen and pantry then:

Clean the kitchen and pantry with vinegar, full strength, or 50/50 with water. Pay close attention to cracks and crevices.

Never put open packages into the pantry.  Put those into sealed containers.

Make sure when replacing items they are in sealed containers.

Maybe these traps are actually attracting the moths.  I would get rid of them.

Use the 50/50 vinegar to spray any moths you see.

I would make sure new products brought into the kitchen and pantry go into the freezer first. Then into sealed containers.

if they keep appearing, they’re breeding/pupating somewhere! we realized we were bringing them home from the food coop periodically. moving everything into glass/thick plastic containers and freezing foodstuffs that had just come in helped  a lot. still a few about.

After experiencing moth infestation in two group houses, I now keep all grains/cereals/flours/beans etc in lidded containers. Flours go in glass or plastic containers with tight lids.  Smaller odds and ends like half-used packs of beans or rice get packed together in a big metal popcorn tin.

Also inspect regularly so you can deal with any bugs before they get out of hand.

Note that you can still get moths/ weevils because the eggs are in the grain you bought or harvested. The containers just keep the pests from spreading to everything else and starting a colony in your cupboard.

Get a chest freezer/fridge and keep all of your grain/nuts/beans/cereal in it. With no source of food, they should die out.
