Which two pests are commonly treated with nematodes in lawn care?

The use of nematodes in lawn care is particularly effective for managing pest populations that are hidden in the soil or that infect the root systems of plants. Grubs, which are the larvae of beetles, cause significant damage to lawns by feeding on grass roots, leading to brown patches and a weakened lawn. Introduced nematodes can target these grubs effectively, providing a biological control method that minimizes reliance on chemical pesticides.

Root weevils, another soil-dwelling pest, also pose a threat to various ornamental plants and lawns. The larvae of root weevils live in the soil and feed on plant roots, leading to stunted growth and plant decline. Nematodes have a proven track record of controlling root weevil infestations, making them a valuable tool for maintaining healthy landscapes.

In contrast, while other pests like ants, termites, fleas, ticks, leaf miners, and aphids can cause issues, they are typically managed through different pest control methods, including chemical treatments or cultural practices, rather than nematodes. This highlights the specific role that nematodes play in targeting particular groups of pests that affect the soil or root systems of plants.
