The selection of roof rats, house mice, and Norway rats as the correct answer is justified based on their significant impact on stored products. All three of these rodent species are notorious for invading warehouses, grain bins, and food storage facilities, leading to substantial financial losses and contamination of products.

Roof rats are agile climbers and often access stored goods that may be located in elevated areas, posing a threat to both dry food supplies and other items stored at height. House mice are highly adaptable and reproduce rapidly, making them a common nuisance in residential and commercial settings alike, often compromising food safety and integrity. Norway rats, being one of the most common rodent pests, can consume and contaminate large quantities of stored goods, and their gnawing can damage packaging, further leading to spoilage and waste.

The other groups listed in the alternatives do not match the same level of impact on stored products. For instance, while deer mice and field mice can cause problems, they typically do not cause the same scale or type of damage associated with the threats posed by roof rats, house mice, and Norway rats. Squirrels, while they may cause damage in specific contexts, are generally not associated with the same type of threat to stored food products as the
