They are pests primarily by their presence, thus the contamination of the food product. Developmental time is about three weeks. Grain mites Grain mites are tiny, pale grayish, wingless, soft-bodied creatures much smaller than psocids. They often are found in stored grain and eventually may be brought into the home in grain food products. In damp conditions, they may build up rapidly to populations that make infested food seem to be alive with the mites.
Developmental time is about two weeks.
Steps in controlling pantry pests Pantry pest infestations may be eliminated by following a systematic and complete control program. Shortcuts may result in control failure. Carefully examine all susceptible foods to determine sources of infestations. Throw away any that are heavily infested. If infested food has further value or if infestation is questionable, heat the food at 130 degrees Fahrenheit for at least 30 minutes or place in a deep freezer at zero for four days.
