I have little worms crawling on my ceiling!
Chances are you have been infested with a stored product pest. Indian Meal Moths and what people term as "mealy worms" can come from a variety of places, so it is important to find the source. So where do you look? The main places to look would be any dry goods like cereal, pasts, oat meal, flour, baking sodas, rice, spices, dry milk, dog and cat foods and bird seed to name a few. You have to look in these items and chances are you will find live worms or moths or what look to be "casings". If you see this the item must be thrown away. Don't stop at one item if it is infested. Continue to inspect all dry goods to be sure and throw away any suspected products. The ones in your home can be taken care of with a vacuum cleaner and once the infested item is gone so will your problems. Happy hunting!
