Non-insect pests, both large and small, do not belong to the insect group. Insects are a specific class of invertebrates within the phylum Arthropoda. They are characterized by having six legs, a three-part body (head, thorax, and abdomen), and typically two pairs of wings.
Non-insect pests can include various organisms from different taxonomic groups, such as:

1. Mammals: Animals like rodents (e.g., rats and mice), bats, and larger mammals can cause damage to crops, stored food, or property.
2. Birds: Certain bird species can be pests in agriculture, especially when they feed on crops or cause damage to structures.
3. Nematodes: Nematodes are microscopic, worm-like organisms that can parasitize plants, causing diseases and affecting their growth.
4. Slugs and Snails: These mollusks are known for feeding on a variety of plants and can cause damage to agricultural crops and gardens.
5. Mites: Mites are arachnids and belong to a different class than insects. They include various species that can be pests, such as spider mites that damage plants by feeding on their tissues.
6. Worms: Various worm species, such as earthworms, wireworms, or cutworms, can cause damage to crops, gardens, or lawns.

It’s important to note that while these organisms are not classified as insects, they can still be considered pests due to the negative impact they have on agricultural or human interests. Effective pest management strategies need to be employed to control and mitigate the damage caused by these non-insect pests.
