Controlling Sod Webworms: Tips for a Healthy Lawn

As homeowners, we all want our lawns to look lush and green throughout the year. Unfortunately, there are numerous pests that can damage our turfgrass and leave unsightly brown patches. One of the most common culprits is sod webworms, which can quickly cause significant damage if left uncontrolled. In this article, we'll discuss how to identify and control sod webworms to keep your lawn healthy and vibrant.

What are Sod Webworms?

Sod webworms are the larvae of small, tan-colored moths that are often seen flying low over lawns in the evening. These moths lay their eggs in the grass, and once the eggs hatch, the larvae begin feeding on the blades of the turfgrass. As the larvae mature, they create silk-lined burrows in the thatch layer of the lawn, where they hide during the day.

How to Identify Sod Webworm Damage

The first sign of sod webworm damage is usually small brown patches in the lawn that appear seemingly overnight. These patches will become larger as the larvae continue to feed on the grass blades. Additionally, you may notice an increase in birds, such as robins or starlings, as they search for the larvae in the thatch layer. If you suspect that sod webworms are causing damage to your lawn, it's essential to act quickly before the problem becomes severe.

Preventing Sod Webworm Infestations

The best defense against sod webworms is maintaining a healthy lawn. Ensure that your turfgrass is receiving enough water and nutrients, and mow regularly to keep the grass at a proper height. Additionally, avoid over-fertilizing, as this can make the grass more attractive to the moths that lay the sod webworm eggs. It's also a good idea to remove any thatch buildup in the lawn, as this provides an ideal habitat for the larvae.

Controlling Sod Webworms

If you've already noticed signs of sod webworm damage in your lawn, there are several methods you can use to control the infestation. One of the most effective options is treating the lawn with a pesticide designed specifically for sod webworms. Be sure to follow the label instructions carefully and apply the product evenly across the affected areas. Another option is using beneficial nematodes, which are microscopic worms that attack and kill the larvae. These can be purchased at many garden centers and applied to the lawn using a hose-end sprayer.

By taking steps to prevent and control sod webworm infestations, you can keep your lawn looking its best year-round. Remember to maintain a healthy lawn by providing adequate water and nutrients, removing thatch buildup, and mowing regularly. If you notice signs of sod webworm damage, act quickly to control the infestation before it causes extensive damage. With these tips, you'll have a beautiful, healthy lawn that you can enjoy all season long.
