FALL RIVER — Spraying has been planned following the detection of mosquitoes carrying West Nile virus in Fall River.

The office of Mayor Jasiel Correia II announced Wednesday that ground spraying will take place in Oak Grove Cemetery and the immediate areas between the hours of 2 and 5 a.m. on Friday, Sept. 9.

"The spraying will be performed by the Bristol County Mosquito Control Project using a man-made pesticide product related to the natural components of the chrysanthemum flower, and also those found in other pesticide products used indoors in pet shampoo, lice treatments and on pets. The active ingredients of the pesticide product generally break down quickly and do not leave a toxic residue," the statement notes.

The mosquitoes were collected in an area near Oak Grove Cemetery.
