Which pest is known to damage food products but is not a fabric pest?

The Indian meal moth is known for its ability to infest and damage various food products, particularly stored grains, cereals, and dried fruits. Its larvae feed on these items, leading to substantial damage that can render food inedible. Unlike fabric pests, which specifically target fibers for nesting and feeding, the Indian meal moth is primarily associated with food storage areas, emphasizing its role in pest management related to food contamination and loss.

In contrast, the clothes moth and fabric pests target textiles and materials made from natural fibers, using them as a food source for their larvae. The flea is a blood-feeding parasite that primarily affects pets and humans, and while the silverfish feeds on a variety of organic materials, it does not specifically target stored food products. Thus, the distinctive characteristic of the Indian meal moth as a pest that causes food damage but does not pose a threat to fabrics makes it the correct answer in this context.
