Chinch bugs feed on turfgrass by sucking out plant juices and injecting salivary fluids into the leaves and stems, causing the plant to turn yellow before it becomes brown. Hot, dry, sunny conditions favor chinch bug activity. They feed on most cool and warm-season grasses including St. Augustine and bermudagrass. Adult chinch bugs are about one-quarter inch long with white wings folded over its black body. They remain actively feeding as long as warm conditions prevail, producing two or three generations per year.
