A mosquito sample found in the St. Rose area of St. Charles Parish tested positive for the West Nile virus, according to St. Charles Parish officials.

Renee Simpson, spokesperson for the parish said the Louisiana Animal Disease Diagnostic Laboratory confirmed the positive sample came from a mosquito trap that was checked Friday.

Simpson said residents are advised to avoid outside activities at dawn or dusk when mosquitoes are most prevalent. It is also recommended that wear longer sleeves and pants and apply mosquito repellant containing DEET.

Residents are also asked to eradicate potential breeding sites by removing any standing water in yards.

“Mosquito Control for the parish is increasing spraying and conducting other abatement measures in the area.” Simpson said.
