Sod webworm control and detection tips
A disclosing solution (soap flush) technique is a useful tool for
monitoring and detecting these pests. Sprinkle a mixture of two
tablespoons of liquid detergent and a gallon of water evenly over a
square yard of turf. The soap will irritate the worms causing them to
crawl to the surface. The recommended treatment threshold for these
pests is typically 10-15 worms in a square yard, after observing obvious
damage to turf.
