With the recent rise in reported cases of West Nile virus in Brazos County, many residents are calling for increased fumigation.
But a Bryan Parks and Recreation official says widespread fogging is not as effective as most think.
According to Bob Holmes, fogging kills only mosquitoes that happen to be flying through the mist at the exact time it's being sprayed. He also says fogging kills many other beneficial insects and can cause severe reactions among residents sensitive to the pesticide.
Both Bryan and College Station discontinued widespread mosquito fumigation several years ago. However the two cities still use it in areas where West Nile infected mosquitoes have been located.
