Sod webworms are the larvae of lawn moths. In the spring, female sod webworms lay eggs, up to 60 eggs per night! Unfortunately, winter doesn't kill off the webworms. Instead, the last generation from the summer build tunnels in the soil and mature. When spring hits, they begin feeding on grass.
The biggest indication of sod webworms is baseball sized brown patches where your lawn is driest. For those who have experienced sod webworms, they can attest the damage to their lawns and how it happens in a short amount of time. Severe damage is usually noticed in July and August.
Another sign is that you'll may even be able to see small white tubes made of silky web at the root level. At dusk, you might even see the larvae or moths flying above your grass.
Sod webworm control must focus on the larva, not the adult moths since spring's first generation of larvae is already at work. Every subsequent generation will cause more larvae to feed off your lawn.
This is why we recommend taking preventive measures now to get ahead of what could cause major lawn damage. We recommend two treatments: one now and another one in July or August. For a limited time, by receiving these two treatments we are offering a one-year warranty from the first initial treatment against the Sod Webworm Larvae.
