1. What Are Armyworms?
Armyworms are a type of caterpillar larvae that feed on grass, wheat, and other crops. As they feed, they can cause extensive damage, making them a major pest problem in the U.S. and across the world. Armyworms can be hard to spot since they’re so small and camouflaged, and they can quickly cause extensive damage to crops, so identifying and controlling them is important.
What to Look For:
- Armyworms are pale green to yellow in color, with a brown, spotted appearance.
- They are typically up to ¾ inch long and have a distinct black head.
- Armyworms feed on the leaves of plants, leaving behind a trail of small, irregular-shaped holes.

Armyworms can be eliminated by using biopesticides, like spinosad-based products, that contain beneficial bacteria or fungi. These products are relatively safe and non-toxic to humans and pets, but can be very effective in controlling armyworms. Regardless, it’s important to always read and follow product directions for use and safety.
In addition to biopesticides, there are several other ways to control armyworms, including:
| Organic Solutions | Inorganic Solutions |
| Crop rotation | Bacillus thuringiensis (BT) |
| Handpicking and disposal | Fenitrothion, Malathion |
| Covering plants with row covers | Template and Acetamiprid |
In most cases, a combination of methods will provide the best control. Keeping your grass and plants healthy is also key. Make sure to maintain regular mowing and irrigation, as this will help to reduce the population of armyworms in your yard and garden.
2. Identifying Armyworms
The first step in getting rid of armyworms is identifying where they are and what kind of damage they are causing. Armyworms come in three forms: fall, true and spotted. All three larvae look quite similar, but there are some key differences to look for:
- Fall Armyworms: They are greenish-brown in color, have light stripes down their back, and measure up to 3/4 inch in length.
- True Armyworms: They are yellowish-green to brown in color, have darker stripes on their front, and grow up to two inches in length.
- Spotted Armyworms: They are yellowish-green to yellowish-brown in color and have spots on their back. They are slightly bigger than true armyworms, growing up to two and a half inches long.
Of course, the easiest way to identify an armyworm is to catch one and take it to a local extension office for identification. But this isn’t always necessary – armyworms have a number of noticeable features, like their dark heads and light bellies. Keep an eye out for large clusters of caterpillars, too, as this is a sure sign that armyworms have invaded your garden.
Armyworms also leave behind visible signs of damage. The leaves of affected plants will be chewed through, leaving small, ragged holes. Additionally, armyworms can damage fruit and vegetables, so if there are any signs of infestation on the fruits or vegetables on your plants, you’ll know to take action.

- Look for webs, droppings or cast skins near affected plants
Eliminating Army Worms
Once identified, there are a few approaches you can use to control the pest. Physical treatments like horticultural oils or insecticides are effective options, as they can stop the worms in their tracks and, when used correctly, have no adverse effect on your plants or farmland. Additionally, there are several biological controls available that can remove army Worms from your land quickly and safely.
| Treatment Type | Applied To | Effectiveness |
|---|---|---|
| Horticultural Oils | Plants | Good |
| Insecticides | Soil and Plants | Good |

Spraying again 10-14 days after the initial treatment can help reduce the population of armyworms.
For an effective chemical control method, the following insecticides are recommended:
- Bifenthrin: This insecticide works as an adulticide and larvicide, helping to quickly reduce the population of armyworms.
- Permethrin: This insecticide quickly acts to kill armyworms and provides long-term protection from reinfestation.
- Trichlorfon: This insecticide works quickly to control armyworm populations and can be used as part of an integrated pest management program.
- Chlorpyrifos: This insecticide works quickly to kill armyworms and has a long-term residual activity.
