Public Health and Wellness Begins Mosquito Fogging

Thursday June 11, 2009

Weather permitting, the Metro Department of Public Health and Wellness will begin spraying for mosquitoes this week. The River Road (Harrod’s Creek) area is first area to be sprayed.  The boundaries of this fogging area are:

North-Sutherland Farm Road;
South-Boxhill Lane;
East-US 42;
West-Ohio River

Mosquito fogging is done between dusk and dawn. Fogging cannot be done if it is raining, if wind speeds exceed 10 miles per hour or if evening temperatures are above 85°.  If fogging activities are canceled due to weather conditions, they will usually be rescheduled for the following weekday evening.  

In determining where to fog, the Department of Public Health and Wellness uses surveillance data, such as counts of mosquitoes in traps distributed throughout the metro area. 

Workers will be spraying a synergized synthetic pyrethroid. This product offers a very low toxicity and odor. Pyrethroids can be used for public health mosquito control programs without posing unreasonable risks to human health. It is registered by the U.S. Environmental Protection Agency and the Kentucky Department of Agriculture for use in adult mosquito control programs. This product is biodegradable.

The Louisville Metro Department of Public Health and Wellness will post areas to be fogged throughout the summer on its website Citizens may also phone the fogging hotline at 574-6641 or call MetroCall at 311 to report a specific mosquito problem.

• Keep children away from the fogging vehicle.
• Park your vehicle off the street when possible.
• Do not tailgate or follow the fogging vehicles.
• Do not stop the fogging truck while it is fogging.
• Go inside and remain indoors while the fogging vehicle is in the neighborhood.
