Chinch bugs are some of the most damaging pests for homeowners and turfgrass professionals alike. These tiny little black insects can be hard to see with the naked eye, but given the right amount of time, they can easily devastate entire St. Augustine lawns. A major symptom of chinch bugs is the yellowing in irregular shapes of turfgrass. Damage symptoms often mimic those of drought. Consider conducting a soap flush test for proper identification.
