Signs of Sod Webworm Presence & Types of Grass They Will Target

One of the most telling signs of sod webworms will be visible at night. If you sit outside and see tiny, pale brown moths flitting around your grass, then you more than likely have sod webworms in your yard. You may also see brown patches that are about the size of a baseball, as well as an increased presence of birds rooting around in your grass to feed on the larvae. It can be easy to confuse sod webworm damage with dog urine damage, but a lawn care professional will be able to tell you what has caused the issue in your grass.

Areas that sod webworms will target are usually the ones that are hardest to water, such as steep slopes, ditches, or banks. Types of grass that are most likely to have sod webworms are:

  • Fine fescue
  • Kentucky bluegrass
  • Ryegrass
  • And others

When Sod Webworms Are Most Common in Pennsylvania

The worst damage from sod webworms generally happens from July through August and can often go undetected during long, hot, dry periods. They are the most common during this late summer period, but will mature into adult moths and lay more eggs that then hatch again in September to cause even more damage.

In other words, you may see many generations of sod webworms in your yard if they are allowed to stay there without any kind of treatment.


How to Prevent Sod Webworm Damage

As with any lawn insect, proactive strategies are the best way to prevent sod webworms from damaging your lawn. The strongest defense against insects is a high-caliber lawn care program that will keep your grass healthy and better able to fight off their infestation. If you do not have a lawn care program and sod webworms are present in the lawn, then you may need an insecticide treatment to control them.
