How to Tell If Your Lawn Has Army Worms
If you’ve noticed brown patches on your lawn or if it seems to be thinning out, it’s possible that army worms are the culprits. These pests are known for their voracious appetite and can quickly damage a lawn if left unchecked. Here’s how to tell if your lawn has army worms and what you can do to combat them.
Identifying Army Worms
The first step in determining if army worms are infesting your lawn is to identify them. These caterpillars are typically about an inch long and have a dark brown or black body with a yellow stripe along their back. They have a distinctive humpbacked appearance and can be found in large, moving groups, which is where they get their name.
Signs of Infestation
Aside from the presence of army worms, there are several other signs that may indicate an infestation:
– Brown patches: One of the most obvious signs of army worm damage is brown patches on your lawn. This occurs when the worms eat away at the grass blades, leaving behind a patchy appearance.
– Grass that’s been pulled up: Army worms are known to pull up grass by the roots, which can be a clear indication of their presence.
– Grass that’s been chewed on: If you see grass that’s been chewed on, it’s likely army worms have been at work. They leave behind a distinctive, jagged edge on the grass blades.
How to Confirm the Infestation
To confirm that army worms are the cause of your lawn’s issues, you can perform a simple test. Collect a few grass samples from the affected area and place them in a container with water. If army worms are present, they will float to the top of the water within a few hours.
Controlling Army Worms
Once you’ve confirmed that army worms are infesting your lawn, it’s time to take action. Here are some steps you can take to control the infestation:
– Handpick the worms: If the infestation is small, you can handpick the army worms off your lawn and dispose of them in a sealed bag.
– Use a pesticide: Apply a pesticide that’s specifically designed to target army worms. Follow the instructions on the label carefully to ensure effective control.
– Mulch your lawn: Applying a layer of mulch around your lawn can help deter army worms and protect your grass.
– Water your lawn appropriately: Proper watering can help your lawn recover from army worm damage and reduce the likelihood of future infestations.
By following these steps, you can effectively identify and control army worm infestations in your lawn, ensuring a healthy and vibrant green space.
