Fogging operations to be conducted in specific neighborhoods

LOUISVILLE, Ky. – (August 18, 2021) The Department of Public Health and Wellness has found mosquitos infected with West Nile virus in surveillance traps in four additional Louisville ZIP Code areas: 40203, 40206, 40208, 40210. Mosquitos with West Nile were previously reported in ZIP codes 40205, 40212, 40214 and 40215.

Mosquito fogging will take place this evening, Wednesday, August 18, in these areas weather permitting: neighborhoods around Churchill Downs, Iroquois, Old Louisville and Irish Hills.

Fogging occurs in the early morning or early evening hours. The Department of Public Health and Wellness uses Zenivex, a synergized synthetic pyrethroid, using an ultra-low volume fogging machine. This product offers a very low toxicity and odor. The U.S. Environmental Protection Agency and Kentucky Department of Agriculture recognize pyrethroids as safe to use without posing unreasonable risks to human health. Zenivex breaks down quickly in sunlight and does not have a residual effect.

West Nile mosquitos are not unusual at this time of year.  People are advised to take the following precautions:

Avoid Mosquito Bites

Mosquito-Proof Your Home

No human cases of West Nile have been reported in Louisville so far this year. 

In most instances, people infected with West Nile virus either show no symptoms or relatively mild symptoms.  However, less than one percent of infected people develop a serious neurologic illness such as encephalitis or meningitis.  Serious illness can occur in people of any age. However, people over 60 years of age are at the greatest risk for severe disease. People with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and people who have received organ transplants, are also at greater risk for serious illness.

To check if your area has been fogged or will be fogged call the mosquito hotline, 574-6641, or visit the department’s website. To make a complaint about mosquitos in your neighborhood call Metro Call at 311 or 574-5000.
