Chinch bug damage can be easily confused with other lawn disorders. In particular, it can be difficult to distinguish from that caused by drought. Finding numbers of the insects is the best proof of chinch bug damage. Bring us an 8″ square of sod (1/2 good and 1/2 damaged) with 1″ of soil attached. We will be happy to help solve your problem!
One product that we have found to be effective for controlling chinch bugs is Nitro-Phos Bug Out Max.
