Usually, when a caterpillar crosses your path you can’t help to think of what a beautiful butterfly it will become. This isn’t the case with sod webworms. While in the larvae stage, these caterpillars can damage your lawn before becoming a moth. Learn the signs and treatment options for sod webworms and get back to daydreaming in your beautiful yard.

What are Sod Webworms?

Head over to a sunny spot on your lawn. See any damage? Any signs of pests? What about an off-white moth with a long snout? While these moths aren’t likely to do any damage, they may already be done from when they were little larvae.

The larvae are less than an inch long and vary in color. You may notice their dark head and spots on their body. They love to chew leaves and will eat entire grass stems.

Webworms get their name from the silk-like tunnels they make. They may drag the grass through these structures to save it for later, and they certainly have a large appetite.

Signs of Sod Webworms

If you don’t notice the larva or the moth, you may notice the damage done. It starts as irregular spots in your lawn. Then you may see the grass turn from green to brown as the spots get bigger.

While the small larvae are hard to see, you may notice the adult moth flying around. Look for the short zigzag flight pattern. If you find a lot of them in your yard, chances are the larvae were also in the area.

Pest Control

Sod webworms do their best work at night. This is why your greatest chance of controlling them is to apply a pesticide during the late afternoon or early evening right before feeding time. There are various products available to deal with webworms. As with any treatment product, make sure to follow the instructions carefully for the best results.

To make any topical lawn treatments more effective, it’s best to make sure your lawn is cut to a proper height and any layer of thatch is removed. This helps the product reach its destination. Many granular products also work better when wet after application. Depending on the level of infestation, you could spot-treat or spray a larger area.
