In article , snipped-for-privacy@example.invalid says... :) I live in Florida, have St. Augustine grass and now have my first cinch bug :) infestation. There are about half a dozen brown spots on the lawn at this :) time. My question is what is the simplest way to get rid of these pests. :) Thanks in advance...Ross :) For quicker results any liquid insecticide on the areas and away from the areas a bit, re apply 7-10 days later maybe three applications to be sure...granules can work but or slower and may end up below where the bug feeds. Make sure it is the bug and not just brown patch, which effects St Augustine, before treating.
