Which pest is known to infest a variety of organic products, including dog food and spices?

The correct answer is the Indian Meal Moth. This pest is particularly notorious for infesting a wide range of organic products, such as grains, cereals, nuts, dried fruits, and even dog food and spices. It has the ability to thrive in stored products due to its resilience and adaptability, making it a common household pest found in pantries and storage areas.

The Indian Meal Moth's life cycle, which includes both a larval and adult stage, enables the larvae to feed on materials that are often present in food storage environments. Their ability to fly allows adults to easily migrate to new food sources, which can lead to widespread infestations. Recognizing the habits and behaviors of the Indian Meal Moth is crucial for effective pest management, particularly in settings where food products are stored.

The other pests listed may also be associated with stored products, but they do not have the same level of association with a diverse range of organic food items as the Indian Meal Moth does.
