The answer to 'why is my sod pests' is that your new sod may be infested with common lawn pests like grubs, chinch bugs, or sod webworms. These pests can quickly damage or kill freshly laid sod by feeding on the roots and grass blades.
Common signs of sod pests include discolored, wilting, or thinning patches in the lawn. You may also notice small insects or larvae if you closely inspect the affected areas. Without proper treatment, these pests can spread and cause significant damage to your new lawn.
