An intrafamily feud landed at the Georgia Supreme Court on Monday, as descendents of the cofounder of a major pest-control conglomerate squabble over the family’s multibillion-dollar fortune.

At issue are trusts established by O. Wayne Rollins, the late patriarch of the family behind Rollins Inc. Four of the nine grandchildren who were to benefit from the trusts are fighting their father and uncle over their shares of the family’s money.
