Yes, Talstar P Professional Insecticide is one of the top choices for sod webworm control. Preventative or low level infestations are treated at 0.18 to 0.25 fl oz in 2 gallons of water per 1000 sq ft followed by ¼ inch of rainfall or irrigation to ensure the active ingredient gets into the subsurface soil layer. For heavy or severe infestations, apply at the 1 fl oz per 2 gallons of water per 1000 sq ft. The manufacturer recommends to time applications to control young larvae, if possible. Spot treatments may be applied when infestations are first detected and the damaged area is small. The treatment will be most effective if applied in the early evening when larvae begin feeding.
