We almost never see mealworms as pests in a home, but they are pests in facilities that store or process grain. Even in these sites, they are not major pests because they rarely feed on clean grain that is food quality. They prefer grains that are old and moldy, and so they are found in dark, damp, musty sites where there is damp grain spillage. In addition to moldy grains, mealworms will also feed on meat scraps, dead insects, and feathers.
