ok guys help me out. a new customer was upset with the last company cause his yard is patching, "dead spots". i first thought grubs and lifted a handful of sod. i found a little grayish worm and also noticed small pencil size holes all through the dead areas. after doing some online research i discovered burrowing sod webworms! ok are these a problem in ohio and if the last company was treating for regular white grubs would the treatment have let the webworms live. furthermore any suggestions on killing these boogers and when?? thanks in advance.
