What do army worms do to your lawn? Armyworms, also known as fall armyworms or sod webworms, are a type of caterpillar that can cause significant damage to your lawn. These pests are notorious for their ability to rapidly infest large areas, leaving behind brown, dead patches of grass that can turn your once lush lawn into an eyesore. Understanding the behavior and impact of armyworms is crucial for effective lawn management and preventing costly repairs.
Armyworms are primarily attracted to grassy areas, including lawns, golf courses, and pastures. They are known for their migratory habits, which can lead to widespread infestations. Once they find a suitable habitat, they begin feeding on the grass blades, causing them to turn brown and wilt. As the armyworms continue to feed, they can create large, circular patches of dead grass, which can spread quickly if left unchecked.
The larvae of armyworms are the primary culprits behind the damage to your lawn. These caterpillars have a voracious appetite and can consume vast amounts of grass in a short period of time. They are also nocturnal, which makes them difficult to spot during the day. However, their presence can be indicated by the signs of damage they leave behind, such as chewed grass blades and small, brown frass (excrement) on the lawn surface.
One of the most concerning aspects of armyworms is their ability to disrupt the ecosystem of your lawn. As they consume grass, they can also harm beneficial insects, such as ladybugs and lacewings, that help control other pests. This disruption can lead to a domino effect, as other pests may take advantage of the weakened grass and beneficial insects, further damaging your lawn.

Understanding what armyworms do to your lawn and taking proactive measures to prevent and manage infestations can help you maintain a beautiful, healthy lawn.
