Today my wife went to make some bread. She noticed some very small insects in the whole wheat and regular flour. Upon further inspection, many of our wheat based products were infested with these critters. The worst infestation was in some buckwheat noodles that looked like swiss cheese.
The bug looks like a dark, barely visible beetle. Maybe about half a centimeter in length. They seem to be depositing a powder everywhere. Maybe this is just flour they've carried around.
What are these guys? How do we get rid of them? How do we prevent them from coming back?
