Had an outbreak of them in Iowa...we lived about two blocks from a large grain elevator.

They can bore thru cardboard to get to boxed grain products like cereal. Ended up storing cereal, pasta, etc. boxes in large gallon-size plastic zip-top bags and that worked.

Got some old-timey fly-paper ribbons and they collected all the adults. Evidently they can communicate as the ones stuck on the fly-paper attract more in to get stuck. At first you get a few an then the number stuck on the paper explodes.

I store that stuff in the freezer now.

I've used the ribbon trap too. They work well.
