You may know the Indian Meal Moth by another name: weevil moth, pantry moth, flour moth or grain moth. Whatever you call them, they can be quite a nuisance if you discover them in your home. They typically feed on dry foods like cereal, flour, pasta, bread, couscous, spices, dried fruit or nuts.
We recently discovered some Indian Meal Moth larvae hiding away in a bag of pistachios in a customers’ pantry. The moths can get into very tightly sealed bags by chewing through them. Infested food will look like it has been webbed together. Once Indian meal moths have been discovered, it may be necessary to throw away all food not sealed in tight containers.
