MONTGOMERY COUNTY, Texas -

For the first time this season, Montgomery County leaders announced they will start aerial spraying to try and get a handle on the growing problem with the West Nile virus.

This year, there have been eight reported human cases, and one Montgomery County resident, an 80-year-old man, is confirmed to have died after contracting the virus.

Most of the cases are in the southern part of the county.

"South Montgomery County is a gateway for mosquito-borne illnesses. It's because of the proximity to Spring Creek and the San Jac River," Commissioner James Noack said.

Local 2 checked and other counties are dealing with the issue as well.

Harris County has reported nine human cases; the city of Houston reports one; Galveston one; Brazoria one, and Ft. Bend County has had zero.

Montgomery County says the aerial spraying is costly and could cost well over $300,000. It's expected to start at some point this week.

The Brazoria County Mosquito Control District says it will conduct aerial spraying in the Pearland area on Thursday and Friday at approximately 6:00 a.m. to 8:30 a.m.
