Will my lawn recover from chinch bug damage?
Plant damage results not only from withdrawal of sap, but from chinch bug saliva, which contain substances toxic to the plant. Drought or heat stress may cause similar browning of turf, but proper watering will quickly rejuvenate the lawn. Turf injured by chinch bugs will not recover as quickly.
