A recent conversation on Mazinfo had an expat seeking info about flour weevils. What to do if you find contaminated food and how to rid your kitchen of it. Stephanie Raney in "How to Get Rid of Flour Weevils and Keep Them Away," writes that you should take all your food out of your cupboards, throw away all that you know is contaminated or that you think might be contaminated. "Be sure to check all sugars, grains, dried beans and breakfast cereals for signs of flour weevils. Do not throw the contaminated food away in your kitchen trashcan you will want to remove it from your home immediately." Then, thoroughly clean and disinfect your cupboards. Even replace the shelf paper.

When you bring in new sugar, flour, cereal, beans etc. first put them in the freezer for four to five days. The freezing will kill any weevils. Raney writes that "...the most important things are to keep foods prone to infestation sealed in airtight containers, to use older food first, and to only buy small amounts of foods that are prone to becoming home to flour weevils at a time. Good advice!
