As a lawn owner, you work hard to keep your turf lush, green and well-fed so your yard can glow with beauty. However, there are some pests which love your work for different reasons such as for food. One such pest that can ruin your efforts to keep a nice lawn are sod webworms. These lawn pests typically become a problem in the fall, as it likes to consume cool season turf grasses. If left untreated, they can do some significant damage to your healthy lawn.

Sod webworms, also known as turf webworms, are the larval or caterpillar stage of the small white-brown moth. The sod webworms are about 1 inch long and the moth are between ½ an inch to ¾ of an inch. They have faintly yellow or brown markings on their wings. There are about 20 different species of sod webworm and they are known for being hungry and destructive during this stage of their life which does not bode well for lawns they find themselves upon.

Sod webworms live above soil level in the thatch. This is where they spin a light webbing and feed on the undersides of leaves. Damage from sod webworms initially go unnoticed by lawn owners but once they multiply to a sizable population, the damage can then become much more noticeable. At first, the damage from sod webworm consumption appears as small, ragged brown spots in the turf. As feeding continues these areas grow larger and result in large patches of dead grass resembling a turf disease.

If you have sod webworms eating up your lawn, you will have to take action before they destroy it. At Solutions Pest and Lawn, we can supply you with everything you need to eradicate this lawn pest--from high quality insecticides to expert guidance and support.

How To Get Rid of Sod Webworms: 3 Step Solution

There are several ways to improve the quality of your lawn after discovering sod webworms. We recommend a combination of cultural means of control with chemical applications as well to put a stop to the sod webworms insatiable appetite. Sod webworms are readily controlled by most liquid insecticides approved for turfgrass such as bifenthrin or cypermethrin. Solutions Pest and Lawn carries the best quality pesticides available on the market which you won’t be able to find at your local garden center or department store. Take a look at our simple 3 step plan to eliminate these irritating pests the right way.

Step 1: Before proceeding with chemical control, it is best to first perform a careful inspection to see where these webworms are residing and whether you have a small or large infestation. Check the damage to your grass. Timing is also important when treating sod webworms. These bugs are known to lay a lot of eggs and it would be best to control them before they hatch and add to the damage.

Step 2:
Once you have completed the inspection, you should then prep your lawn for chemical treatment. The best way to do this is by first mowing your lawn and removing the clippings immediately. This should be done because it makes the sod webworms more vulnerable by not having all that grass to hide in and it also enhances insecticide movement on the turf canopy. After mowing, water your lawn.  A thorough irrigation of about 1/2 to 3/4 inch of water prior to application will move webworms closer to the surface.

Step 3:
Now it’s time to break out the big guns. Load up your sprayer with an insecticide labeled for turf application such as Sylo or Reclaim IT. Apply at a rate of up to 1 oz per 2 gallons of water to cover 1,000 square feet of lawn. Use a hose end sprayer when applying to get good thorough coverage. Apply later in the day as sod webworms are most active at night time. We then recommend irrigating lightly (⅛ inch). After applying a liquid insecticide it is best to go back and apply a granular chemical for long term extended release control of the grubs. We recommend Bifen LP as the primary granular to use for them.
