In southern areas St. Augustine grass is especially susceptible while in northern states bentgrass lawns are prone to infestations. Several generations are possible each year.
Chinch bugs prefer the bright sunny areas of the yard and dry conditions.
Infected areas will have a bleached out appearance at first and then turn brown and die. A thorough spraying with a dursban spray 2-4 times a season will keep chinch bugs and other lawn pests under control.
