Preventing Sod Webworms Can Be Difficult
But You Can Prevent Extensive Damage
However, there are a couple things you can do to help prevent extensive damage to your yard.
Properly Maintain Your Lawn
Also, an overfertilized and over watered lawn can be even more enticing to the moths when laying eggs, so maintaining proper fertilization rates and irrigation in your lawn care schedule will help to keep your lawn healthy but not too attractive to the moths.
Reduce Excess Thatch
Proper thatch maintenance will reduce this shelter and will also make it easier for you to do your thorough inspection, since the worms will be easier to see when they're near the soil if there is reduced or normal thatch levels.
