For some reason the barley always gets them, that is why I always put it in a bag but I think they eat thru it. That Kashi cereal is like health food store stuff it draws them like magnets. I guess if we freeze everything 1st we can kill them before they get started. Oh well at least the pantry is clean now. I use to sell Tupperware too. Don't know how I did it because I was kinda shy.
