Oklahoma City and several surrounding towns are stepping up their efforts to control the mosquito population.
The goal is to put a dent in the number of illnesses from the West Nile virus.
In Oklahoma City the mosquito hunt has gone high tech.
Dropping a camera on wheels 10 feet below the sidewalk, Derek Johnson and his partner are piloting the machine via remote control through a storm sewer.
"As we go through driving, we'll find pockets of breeding colonies. We can reduce the number of adult mosquitoes coming from these sources," Johnson explains.
City crews treated a mosquito infestation in the storm drain last week.
Checking on the results, Derek said the larva have all been killed quickly and safely.
"It's much easier to send a camera in there than a human being. It makes it a lot easier," Johnson says.
Nearby neighbors support the city’s proactive approach to combating the spread of West Nile.
Other cities like Moore are also doing their part by spraying mosquito-killing chemicals using spray trucks.
Moore's spraying will focus around city parks and other targeted neighborhoods.
Oklahoma City has never sprayed for mosquitoes and said they won't start now.
