You need to find exactly WHAT they are eating. This may include different things, as all stages of the pests may be feeding on multiple products. The first and most obvious place to start is the kitchen. It sounds like you have a good start there; next, bathroom and closets. This could get tricky, as the larva can feed on starch alone. Be patient and diligent, and continue to remove any larvae or adults you find. When you find out what they are eating, REMOVE it completely from your home, then address air-tight ways of storing and using that product. You may have to rethink how things are stored around the house. Don’t give up!
