Ground Spraying

Overview


Following guidelines from the Centers for Disease Control and Prevention (CDC), the City of Burleson’s plan for mosquito control for 2016 includes ground spraying for mosquitoes in predetermined zones where a mosquito trap confirms West Nile Virus or where a reportable human case of West Nile Virus was confirmed. In cases of other mosquito borne diseases, treatment and prevention will follow CDC, State, and local health authorities recommendations. 
     

City will spray Zone 3 and Zone 4 on October 29 and October 30, 2016

 

On October 28, 2016, the City’s environmental services division was notified that a mosquito trap tested positive for West Nile virus. The trap is located in Zone 3, in the area of Wicker Hill, Wilshire Boulevard, Wicker Way, Oakbrook Drive, St. Andrews, Glen Ranch, Clubhouse, Shoreline Drive, and Hawks Ridge Trail and Zone 4, in the area of Hidden Creek Parkway, Burleson Boulevard and Hurst Road.

The City of Burleson will conduct ground-based spraying for mosquitoes between 9 p.m. on Saturday, October 29, and then again Sunday, October 30. 
The ground spraying will be performed by trucks with foggers in targeted subdivisions within the designated spray zones.

Preventing Outbreaks

 
In 2012, Texas was the center of one of the worst West Nile Virus outbreaks ever recorded since the disease first appeared in the United States in 1999. In Burleson, 4 mosquito traps tested positive for West Nile Virus in early summer of 2012. The City contracted with a private company to do ground-based spraying in targeted areas where 4 human cases of West Nile Virus were confirmed as well as in any area where a mosquito trap tested positive for West Nile Virus. The ground-based spraying was done in August and September of 2012. 
 

Focus

 
In 2016 the focus is on the container-breeding mosquito, or urban mosquito that has a short flight range. The number of traps increased from 6 to 8 per week to 14 traps in 12 designated spray zones throughout the mosquito breeding season (May 1 - September 30). The objective of this program is to control mosquito larvae before they develop into biting adults. During the 2016 season, waterways, historically known breeding sites and complaint locations are inspected and treated as necessary. Once treated, those sites are inspected periodically.  
 

Pesticide

 
The pesticide that was used for ground spraying in 2016 is Environ 30-30. The active ingredient in this product is Permethrin (see Permethrin fact sheet). Permethrin is a man-made chemical that acts like the natural insecticide in the chrysanthemum flower. Because the product is applied at very low concentrations, it is not likely to harm the health of adults, children, or pets.

The actual amount of dilute insecticide that lands on a typical quarter acre lot is less than 1/3 of a teaspoon. The actual amount of active ingredient that lands on the same lot is less than 5/100ths of a teaspoon (2 or 3 medicine dropper drops).
