Step : Keep The Lawn Mowed To A Reasonable Height And Keep Grassy Weeds At Bay
In many areas, natural predators can help keep armyworms in check. Aim to make your garden a better environment for natural larvae predators, such as birds and beneficial insects like ground beetles, rove beetles, and ladybugs.
Long grass and grassy weeds can attract adult armyworms. A well-maintained garden creates a less attractive environment for the adult moths to lay their eggs. Keeping grasses short and removing fallen debris also exposes armyworm hiding spots, so natural predators can pick off existing bugs. Keeping a healthy yard will also help your grass or plants bounce back in the case of a minor armyworm infestation.
If you suspect armyworms as the cause of your garden woes, its important to identify and treat the problem quickly. Armyworms can lay devastation to a lawn or garden in a matter of days. At the first signs of brown patches and chewed plants, look for the small armyworm larvae, which are identifiable due to their green, yellow, brown, or reddish stripes that span their body length. Then, its time to consider treating your yard. With a few simple treatment steps and regular yard maintenance, you can keep armyworms at bay and help your garden flourish.

After hatching, armyworm caterpillars create web-like nests in your grass. These web tunnels allow them to take shelter in the lawn during the day and feed safely at night. As they begin to grow into adults, they will venture farther and farther up the blades of grass until they can seek out other food sources. They will dine on pretty much any plant they can find, including grasses such as bermuda and zoysia, but also crops, such as peanuts, corn, lettuce, cabbage, and soybeans. Corn is actually their preferred meal.
As mentioned previously, armyworms are mainly active at night, so unless youre taking the time to go outside with a flashlight and scour the lawn, you probably wont notice the caterpillars themselves. Still, youll certainly notice the damage they leave behind. Some of the signs of armyworm damage include the following:

What Are Army Worms
Army worms, also known as lawn army worms, are the larvae of the army worm moth . They are a major pest of turf and pastures and are particularly problematic in tropical, subtropical, and warmer coastal areas of Australia.
Army worms typically target healthy pastures, including Couch, Buffalo, and Kikuyu, among others. Army worms will infest the best looking turf in the neighbourhood and feed on it, before moving on to a nearby lawn.
Army worm moths lay clusters of hundreds of eggs in areas adjacent to lawns, including nearby plants, walls, fences, or buildings. When these eggs hatch, young larvae descend onto the lawn on fine silk threads.
Army worm larvae start out green but become brown with lighter stripes as they mature. The lifecycle of the army worm, from egg to adult, lasts approximately six weeks, with the larvae pupating in the soil before emerging as fully grown moths.
Army worm infestations are most prevalent through the warmer months, from late spring to early autumn.
What Are Lawn Armyworms & How To Get Rid Of Them
Armyworms are generally found in the Northern Territory, Queensland, New South Wales and the Australian Capital Territory.
Its called Armyworm because of the army-like nature, where large numbers march into an area and feed on lawns, turf and various plants in the garden, swiftly decimating expansive areas of vegetation.
Lawn Armyworm can develop rapidly into near plague proportions and quickly cause significant damage in the garden. To help control these destructive pests, its important to regularly monitor, identify correctly and treat at the earliest sign of infestation.

Description And Life Cycle
Adult. The adult fall armyworm is an ash-gray moth with a wingspan of about 112 inches . The front wings are mottled and have white or light gray spots near the tips. The back wings are white with a narrow, smoky-brown edge. Moths become active at twilight and feed on nectar. They have an average life span of 2 to 3 weeks.
Eggs. The female moths lay eggs at night in masses of several hundred. They prefer to lay eggs on light- colored surfaces such as fence rails, tree trunks, and the underside of tree limbs. They will also lay eggs on the grass itself. Most eggs are laid 4 to 9 days after the female emerges from the pupal stage. The eggs are light gray and covered with grayish fuzz from the females body. These masses darken with age, and the eggs hatch within 2 to 4 days. All the eggs within a mass hatch at about the same time.
Pupae. Fully grown larvae burrow into the soil and form pupae. The moths emerge in about 10 days in summer.

When the army worms are young, they are also very vulnerable to heat and too much sunlight can kill them. So, cutting the grass short and watering it often can do the trick. If you find army worms in your garden, use a spray bottle to spray them with water. It is because when they are young, they are very much susceptible to even moisture..

S To Help Your Lawn Recover From Faw Damage
- After you’ve applied your insecticide treatments and if it’s been four weeks since you fertilized, we recommend applying 5-10-30 fertilizer with Acelepryn to your lawn ASAP to give it a boost in regrowing and provide continued protection.
- Thoroughly water your lawn until it greens back up. This is important for established sod, but is especially important for new sod that does not have the root structure in place to help it recover. Water, water, water!
While warm season grasses, given proper care, will typically recover from FAW damage, damage to tall fescue is often much more significant.
Tall Fescue lawns simply do not have the same tolerance to FAW activity, particularly if it is not very well established. As a result, FAW damage in tall fescue often requires overseeding or re-sodding in order to repair the damage. A new lawn can go from fine one day, to a complete loss in as little as 24 to 48 hours. Tall fescue users cannot take the FAW threat too lightly.
We are here to help you if you have any questions about diagnosis or treatment.

How To Get Rid Of Armyworms Organically
Getting rid of armyworms organically requires more time than using pesticides. But it is a far better option for a variety of reasons:
- Organic methods are harmless to both humans and beneficial insects. Just look at our review for the best pet safe weed killers. The more organic they are, the safer. Also, definitely read this informative article on how long to keep a dog off grass after using a weed killer.
- They are cheap and, sometimes, free.
The first organic method that you can use is Beneficial Nematodes.Nematodes occur naturally in dark and moist places. They are microscopic parasites that are invisible to the naked eye. Once you release them in the soil, they track down the larvae, in our case armyworms, and kill them.
The main quality of these parasitic organisms is that they are harmless to humans, pets, and plants. So, you can use them and not have to worry about any side effects.
Next up, you can also set up Pheromone Traps. Pheromone traps should only be used at the start of moth season i.e. early summer. These traps attract moths using sex pheromones. As a result, the moths get trapped and cant lay any eggs.
Even so, the effect of pheromone traps is negligible compared to using insecticides especially if the timing is not right.
Encourage these natural armyworm predators either by refraining from using pesticides or by releasing them in your yard.
This way the birds will come for the plants but stay for the moths. Its a win-win.
