For sod webworm and cutworm, do not irrigate following application. They continue to be very destructive on turf by burrowing in the soil and feeding on roots and stems of grasses. Many times plants not actually fed on are affected by the soil drying out as a result of mole crickets' burrows. Feeding usually occurs at night with each cricket covering several feet a night. Usually, in late April or early June, new adults emerge and begin mating flights.
Females build cells in the soil where eggs are laid.
Each cell contains about 35 - 40 eggs that hatch in 10 to 40 days, depending on the temperature. Nymphs become adults by the following winter, but most overwinter as immatures. There is one generation per year. Target control toward the young nymphs. Since young nymphs occur more frequently in June and July, consider treatments at this time.
