🌱 ARMYWORMS: SMALL PEST, BIG APPETITE! 🐛
It’s armyworm season, and these little pests can cause a LOT of damage to a healthy lawn in a surprisingly short amount of time.
🐛 What are armyworms?
Armyworms are the caterpillar stage of a moth. They get their name from the way they can move across an area in large groups—almost like an “army”—feeding as they go.
🌱 What do they do?
Armyworms feed on grass blades and can quickly turn a thick, green lawn into an area that looks brown, thin, scalped, or drought-stressed. When populations are heavy, noticeable damage can seem to appear almost overnight.
🔎 How do you know if you have them?
Keep an eye out for:
• Brown or thinning patches that appear suddenly
• Grass blades that look chewed or ragged
• An unusual number of birds feeding in one area of the lawn
• Small caterpillars crawling through the turf, especially early morning or late afternoon
• Damage that seems to spread across the lawn from one day to the next
One easy check: mix a little dish soap with water and pour it over a small section of suspicious turf. If armyworms are present near the surface, the solution can encourage them to crawl up where they’re easier to spot.
🛡️ Can you prevent them?
Regularly inspecting your lawn is one of your best defenses. Armyworm outbreaks can develop quickly, so catching them early can mean the difference between minor feeding damage and a badly damaged lawn.
Keep your turf properly watered and maintained, but remember—a healthy lawn isn’t necessarily an armyworm-proof lawn. They can show up even in well-maintained turf.
🚨 What if you find them?
Act quickly! Armyworms can consume a tremendous amount of grass in a short period of time. Lawn insecticides labeled for armyworm control are available, but always make sure the product is labeled for your turf type and follow the label directions carefully.
The good news? Armyworms primarily eat the grass blades rather than the roots and growing points of many established warm-season grasses, so turf can often recover with proper care once the infestation is controlled.
🌱 The biggest thing to remember: DON’T IGNORE SUDDEN CHANGES IN YOUR LAWN.
If an area goes from green to brown seemingly overnight, take a closer look. It may not be drought or disease—something hungry could be moving through!
