I've found some critters (not the cats) crawling around in some of my grains. Internet research convinces me that they are Sawthoothed Grain Beetles, Oryzaephilus surinamensis. The infestations are small and confined to the plastic canisters holding the grains. I've found them in some of my bulk soft wheat and my bulk barley; also some mixed grains using the wheat and the barley.
I'm pleased that the first site I found was http://www.ellenskitchen.com/pantry/storage1.html . The other sites I looked at had me going through a procedure almost as extensive as when I had a flea infestation. But I don't store my grains in cardboard boxes, so the beetles didn't stray far.
Upon finding them, I spent time trying to sort them out from the grains. I knew that I would eventually be cooking the grains in whatever form, so I wasn't overly concerned. Ellen's Kitchen points out, "Insect eggs and worms are the reason traditional vegan societies did not get vitamin B-12 deficiencies! With improved storage techniques, deficiencies DO develop and this nutrient has had to be supplemented." It also say, "If all else fails, remember black sesame seed, poppyseeds and raisin bits cover a multitude of intrusions (a little cook's joke)."
I made benne wafers a few weeks ago for an event and used some of the soft wheat ground into pastry flour. Some of the gentlemen thought there was an exotic flavor to them. It was probably the toasted sesame seeds, but they were happy when I told them there might be some bugs in it.
I have not seen any threads discussing these insects. Have others had infestations in their granaries? What have you done?
