A Comprehensive Guide to Identification, Damage, and Control
Armyworms are common pests that can cause extensive damage to crops, gardens, and lawns. They are the larvae of several species of moth in the family Noctuidae, and they are named for their tendency to move in large, “army-like” groups as they consume vegetation.
In this article, we will discuss the characteristics of Armyworms, how they cause damage, and how to identify and control them using natural methods. We will also provide location-specific advice for dealing with Armyworms in Live Oak, FL (USDA Zone 8B).
Armyworms are generally light green or brown in color, with a distinct “V” shape on their head. They have several pairs of legs, and their bodies are covered in small bumps or bristles. Adult Armyworms are moths, and they are usually brown or gray in color with distinctive markings on their wings.
Armyworms cause damage to plants by feeding on their leaves, stems, and flowers. They can quickly defoliate an entire plant, and they are especially damaging to crops such as corn, wheat, and other grains. They are also known to attack grasses, such as those found in lawns and golf courses.
Natural Control Methods
Biological Control: Biological control involves introducing natural predators of Armyworms, such as birds and parasitic wasps, to your garden. You can attract birds by providing bird feeders or birdhouses, and you can encourage parasitic wasps by planting nectar-producing flowers and providing them with shelter.
Cultural Control: Cultural control involves practices that make your garden less hospitable to Armyworms. This can include crop rotation, where you alternate the types of plants you grow in a given area, to prevent Armyworms from establishing themselves. You can also use barriers, such as row covers, to protect your plants from Armyworms.
Mechanical Control: Mechanical control involves physically removing Armyworms from your garden. This can be done by handpicking them off your plants, or by using a vacuum or hose to suck them up. You can also use sticky traps to attract and capture Armyworms.
Chemical Control: Chemical control involves using pesticides to kill Armyworms. This is typically a last resort, as pesticides can be harmful to beneficial insects and other wildlife in your garden. If you do choose to use pesticides, make sure to follow the instructions carefully, and use them only as a last resort.
