When turf turns yellow in August and early September, suspect chinch bugs. They are found primarily in the sunny areas of your lawn, and cause areas that turn yellow, then brown, and then die. These patches often first appear near sidewalks, driveways, streets, and other borders such as railroad ties or flagstones that reflect heat onto the lawn. The yellowish spots eventually spread outward into the rest of the lawn, showing the greatest damage at their centers where the chinch bugs congregate. Spread the grass gently with your fingers and look in the thatch, near the soil surface. Chinch bugs are usually very active in the summer, so you will be able to see them scurrying around, especially on warm summer days. If the chinch bug population is small, predacious beetles will control them. If the population is large, you may need to apply an insecticide to your lawn.
