Green Bee Lawn Care approaches sod webworm prevention differently. Rather than treating for sod webworms once the problem has already started, we work to prevent your lawn from getting infected in the first place. We use a high-tech, non-toxic insecticide that only needs to be applied twice per year, once in April and again in July. Our applications are safe for children and pets, and are guaranteed to last 90 days, leaving your lawn free from sod webworms all season long.
