Which common household item can be used to sample for sod webworms?

Using dishwashing detergent to sample for sod webworms is an effective method because the detergent works by breaking down the surface tension of water. When you mix a small amount of dishwashing detergent with water and apply it to the grass or soil where you suspect the presence of sod webworms, it can cause the larvae to come to the surface. This is because the detergent disrupts their environment, making it difficult for them to remain submerged in the grass or soil.

Sod webworms tend to hide in the thatch layer of turf or soil during the day, and by using this method, you can bring them out for easier identification. Sampling for pests using household items like dishwashing detergent is a practical, low-cost strategy for homeowners and pest management professionals alike to assess the presence of these harmful insects without the need for specialized equipment or chemicals.

The other options, while commonly found in households, do not have the same effect or purpose when assessing for sod webworms.
