Merit can be used as suppression but not as a preventative. After you have them under control recheck the turf in 10 days. Eggs will hatch and need to be killed.

Chinch bugs
If you or your friends have St Augustine turf you have to start looking for Chinch bugs around mid June. These b.b. size insects can devour a lawn in a matter of days. Infected areas will look dry. If the lawn still looks dry or even dryer after you increase the water you may have Chinch bugs. Look at the affected area just where it meets the normal turf to find the insects. Bifen is the control I've used.
