There are some little brown moths, very small that usually come into a house through grain foods like flower, oatmeal, rice, granola cereal etc.

They are at first very tiny eggs, impossible to detect. Then they hatch into small larvae that stay buried in the product and very quickly go into a pupal stage.

You probably won't ever notice them until they come out as small brown moths.

These will leave the kitchen and you'll find them everywhere in the house. If you find hanging clothes that have been eaten is is often these moths that are the culprit.

The first thing to do is go through the kitchen shelves and find the source. If you shake the package and notice tiny bits of the product that sticks to the packaging by a spiderweb like substance, that's it. Throw it out in the outside trashcan.

Check everything.

Another possible culprit in some areas is silverfish.

For them you use the same bait as for sowbugs.
