Eggs are deposited in the spring. Nymphs begin feeding immediately after emerging from eggs. A second generation is produced later in the summer. Second generation adults overwinter. Yellowed or browned areas in lawns are an indication of something amiss.
Chinch bugs feed on grass near the soil interface or just below the soil surface.
Prewatering may improve the movement of a spray material to the action site. Follow label directions to determine dilution and application rates. Do not reenter the area until the grass has dried.
