Moths contaminate food in the pantry, making it unhealthy for humans to eat. If the problem persists untreated, a food supply could become completely inedible. Foods that have been heavily infested by moths should be thrown out. Small servings of susceptible foods should be refrigerated. If you are not sure if a food item has been infested, it may be heated in shallow pans in the oven for at least half an hour at 130 degrees, or deep freezed at 0 degrees for four days.
The cabinets and shelves that have been victim to infestation should be emptied and vacuumed. They should then be washed down with hot water and soap.
While insecticides should never directly come in contact with food or utensils, there are some household formulas that may be used to treat areas of food storage. Pyrethrins may be used as well as pyrethroid insecticides, which can help control the moths in the pantry. Before treating with insecticides, all food and utensils should be removed to avoid contamination. Treating cracks and crevices is most effective since pests tend to dwell in these places. Of course, directions should always be read and followed when using pesticides. This is especially critical when treating areas near food or food prep areas. If treating an area where food is stored, such as the pantry, use only products marked for use around food storage areas. Once pesticides have been used, pantry shelves should be covered with foil or clean paper before returning food or utensils to the shelves. If the problem continues after following these steps, a professional pest control operation should be contacted.
