Soil dwelling pests encompass a wide range of organisms. Nematodes are microscopic, thread-like worms that can attack plant roots, leading to stunted growth and yield loss. Wireworms are the larvae of click beetles and are known for damaging the roots and tubers of crops like potatoes. Grubs, the larvae of scarab beetles, feed on the roots of grasses and cereals. Root weevils are beetles whose larvae can severely damage a variety of plants by feeding on their roots.
