OLMOS PARK - In the battle to stop the spread of West Nile virus some cities have turned to aerial spraying. The problem with that is spraying gets in the air, and some say breathing that in is not the healthiest option.

So, in lieu of spraying, the City of Olmos Park has an alternative plan to combat the West Nile virus.

City Manager Michael Simpson said when it rains the city will put larvicide granules in the storm drains.

Our objective is to kill them before they become airborne, he said.

The city manager said the main benefit of using granules is that nothing is sprayed into the air.

I'm not quite sure if they're as effective as the aerial spray, said Olmos Park mom Julie Miggins.

But for Patrick Simpson, who takes a four-mile walk every day through the small upscale city, the use of granules is a breath of fresh air.

I was a heavy smoker for a long time so anything I breathe in is going to cause some irritation, he said.

The downside to not spraying is granules do not kill adult mosquitoes but only mosquito larvae.
