Mosquito spraying continues in county: Officials say effort will keep up until temperatures are low enough to kill West Nile-carrying insects

Local governments will continue to spray for mosquitoes until temperatures are low enough to kill the insects, which spread the West Nile virus.

The Johnson County Health Department is waiting for a report from the state on whether a Bargersville resident has contracted West Nile virus, county health department administrator John Bonsett said.

The county sprays for mosquitoes as needed, and the Franklin and Greenwood street departments spray on a weekly basis. All three departments hope to prevent the spread of the West Nile virus by killing any insects that carry it.

The health department began spraying in the unincorporated parts of the county last week and has been spreading chemicals in pools of water that might be breeding sites for the insects.

The chemicals prevent mosquitoes from developing and could kill thousands of mosquitoes at a time, Bonsett said.

The option is more cost effective than spraying.
