Ground Spraying


Following guidelines from the Centers for Disease Control and Prevention (CDC), the City of Burleson’s plan for mosquito control for 2017 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 8 on October 14 and 15, 2017


On October 13, 2017, the City’s environmental services division was notified that a mosquito trap tested positive for West Nile virus. The trap is located in Zone 8 -  in the area of Gregory Street, Warren Street, Miller Street, Dobson Street, Hidden Creek Parkway, Hidden Vistas, Irene Street, and Arnold Street.

The City of Burleson will conduct ground-based spraying for mosquitoes between 9 p.m. on Saturday, October 14, and then again Sunday, October 15

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. 


In 2017 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 2017 season, waterways, historically known breeding sites and complaint locations are inspected and treated as necessary. Once treated, those sites are inspected periodically.  


The pesticide that is used for ground spraying 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).

Precautionary Measures

 The City has hired a private contractor to conduct the spraying. Although the product that is being sprayed from ground level produces no significant health risk, residents are still advised to take precautionary measures if spraying occurs in their neighborhood.

• Whenever possible, stay indoors during spraying.
• Some individuals are sensitive to pesticides. Persons with asthma or other respiratory conditions are encouraged to stay inside during spraying since there is a possibility that spraying could worsen these conditions.
• Central air conditioners may remain on. Persons with window unit air conditioners who wish to reduce the possibility of indoor exposure to pesticides should set the air conditioner vent to the "closed" position or choose the "recirculate" function.
• Remove children's toys, outdoor equipment and clothes from outdoor areas during spraying. If these items are exposed to pesticides, wash with soap and water before using again.
• Remove pets, along with their food and water bowls, from outdoor areas during spraying.
• Wash skin and clothing exposed to pesticides with soap and water.
• Any produce grown, stored or kept outdoors and exposed to spraying should be washed thoroughly before cooking or eating.
• Anyone experiencing adverse reactions to pesticides should seek medical care or call 911.
