The eggs begin hatching during May and early June. Nymphs feed and develop during the summer. There is one generation a year, although egg laying and hatching may be spread out over several weeks. Nymph damage to grass is usually obvious by mid- to late July. By this time the nymphs are large enough to cause noticeable feeding and tunneling damage.
Many mole crickets reach maturity by fall and fly again.
However, mating is not known to occur during the late season. Control Mole cricket control depends upon the season of the year and the life stages that the pests are in at the time. Control is dependent upon an annual, well-timed plan. Timing of controls and cultural practices is as important as the choice of insecticides. Overwintered mole crickets become active in March and April.
