Ground fogging is scheduled in some areas after mosquito traps tested positive for West Nile virus. The affected areas include parts of Denton County, with specific locations mentioned as Harvest, Argyle, Aubrey, South Paloma Creek, and Hickory Creek. It is unclear if the issue is limited to these areas, as other regions, such as Louisville and possibly areas near New Orleans, may also be experiencing high mosquito populations and West Nile virus concerns.
