Do you have moths or other insects in your cupboard or pantry? Fill a small bowl with 1 1/2 cups apple cider vinegar and add a couple of drops of liquid dish detergent. Leave it in there for a week; it will attract the bugs, which will fall into the bowl and drown. Then empty the shelves, and give the interior a thorough washing with dish washing detergent or 2 cups baking soda in 1 quart (1 liter) water. Discard all wheat products (breads, pasta, flour, and such), and clean off canned goods before putting them back.
