Armyworms earn their name. They start their life as small one- to two-inch-long worms before completing their lifecycles as moths. After taking their adult form they lay eggs and the pupae feed on your grass leaving what was once a beautiful lawn into a desiccated wasteland. Unfortunately, they will do this to almost any plant they can get to. Damage is typically in late summer and can last up to the first frost that fall. And like their name they tend to travel together in Squads, (hence the army) and can even produce multiple generations in a single growing season. Since the adult moths do not over winter in the Carolinas, it is hard predicting their activity each year. 2021 saw record high numbers in the US.
How do I save my Lawn from Insects?
No matter the size of your lawn, whether it is a tiny postage stamp or rolling acres your lawn is the first impression many people have of your home or business. But if you see some of your grass dying or clumping up you might have a problem with insects in your lawn. There are actually a few different types of insects that may be damaging your lawn and the methods to treat them vary.
While the appearance of dead grass or discolored spots in your lawn area a good indication of a problem other evidence of lawn pests might be blades of wilting grass, bite marks or seeing an increase of birds in your lawn. While you may see more insects on the surface of your lawn there could be insects under the lawn’s surface in the soil itself. These are sub-surface insects and may give themselves away with evidence of holes or tunnels in your lawn or/and missing/damaged roots.
