This is the third area of the city officials have sprayed after testing positive for the West Nile virus.
The department has sprayed the east side, downtown, and now the west side of Evansville.
"That's my job. I'm trying to keep you from getting sick in Vanderburgh County," says Keith Goy.
This truck, the yellow light, and fog spraying out of the back makes for one lean mean mosquito killing machine.
Tonight, Keith Goy with the Vanderburgh County Health Department, sprays for mosquitoes on the west side of Evansville.
"We are going from Addison to Bosse Avenue, doing some of the area around Carpenter Creek. That's where there are some low areas on the west side, and we get a lot of pond water there," says Goy.
This year three areas in Evansville tested positive for the West Nile disease.
Already spraying the east side and downtown, tonight health officials spray the west side. Goy says this machine shoots a fog high into air to help kill the pests.
"There's a very small droplet size, that's meant to float in the air for a while. Then the mosquitoes will fly through it, get it on their body, and that's how it kills them," says Goy.
So far, in Indiana, sixteen counties have tested positive for West Nile.
"We actually have 53 different types of mosquitoes in Indiana. Of those, very few are actually considered a disease carrier that we are concerned about," says Goy.
Goy says the goal is to catch the mosquitoes at their breeding sites, near water. He says people should eliminate standing water in their yards like empty flower pots, bird bathes, even clogged gutters. "We can come out and check. We can treat those areas and kill the mosquito larvae for you. There's no charge for that. That's really what we are trying to do is catch them at their source," says Goy.
The Vanderburgh County Health Department suggests other ways you can help protect yourself from mosquito bites.
Here are some tips they suggest: avoid being outside around dusk or dawn, wear light colored clothing, keep your grass trimmed, eliminate water in your yard, and wear bug spray.
