The Florida Department of Health in Broward County has confirmed a locally acquired case of West Nile Virus. As a direct response, the Broward County Mosquito Control Section will spray organic larvicide as part of an integrated pest management approach that also includes public outreach, adulticide application and setting mosquito traps. Truck-mounted larviciding will be performed between the hours of 10 PM and 6 AM, weather permitting, August 5 - 22, 2020. The areas being targeted are portions of Hollywood, Pembroke Pines, Davie, and Southwest Ranches. (See map below of the spray areas in Hollywood).
Residents and business owners are encouraged to survey their properties frequently to remove any standing water in common mosquito habitats such as buckets, tires, planters, bird baths and fountains. By reducing the number of mosquito breeding habitats, residents will reduce the number of adult mosquitoes that could otherwise transmit diseases.
The larvicide being used is VectoBac WDG. It is not harmful to humans, pets, bees, aquatic habitats or environmentally sensitive areas. The active ingredient is Bacillus thuringiensis israelensis (Bti, strain AM6552), a naturally occurring, biodegradable bacterial mosquito larvicide. It is certified by the Organic Materials Review Institute (OMRI) and is registered for use by the US Environmental Protection Agency. In addition, VectoBac WDG has been reviewed by the World Health Organization and is listed as a recommended formulation for control of mosquito larvae.
Broward County Mosquito Control Section continues to work closely with the Florida Department of Health and Code Enforcement partners in Broward’s 31 municipalities to reduce the population of mosquitoes and their habitats.
Any Broward County resident experiencing mosquito problems can request service by calling 311 or by completing the online Mosquito Service Request Form.
West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. There are no vaccines to prevent or medications to treat WNV in people.
Most people infected with West Nile virus do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms such as headache, pain, and fatigue. People with mild illness typically recover within about a week with symptomatic treatment. Less than one-percent of infected people develop a serious, sometimes fatal, illness. Symptoms typically appear between two and 14 days after the bite of an infected mosquito. People over the age of 60 and individuals with weakened immune systems are at an increased risk for severe disease
DOH-Broward reminds residents and visitors to avoid being bitten by mosquitoes and to take basic precautions to help limit exposure.
To protect yourself from mosquitoes, you should remember to “Drain and Cover”:
DRAIN standing water to stop mosquitoes from multiplying.
- Drain water from garbage cans, house gutters, buckets, pool covers, coolers, toys, flower pots or any other containers where sprinkler or rain water has collected.
- Discard old tires, drums, bottles, cans, pots and pans, broken appliances and other items that aren’t being used.
- Empty and clean birdbaths and pet’s water bowls at least once or twice a week.
- Protect boats and vehicles from rain with tarps that don’t accumulate water.
- Maintain swimming pools in good condition and appropriately chlorinated. Empty plastic swimming pools when not in use.
COVER skin with clothing or repellent.
- Clothing - Wear shoes, socks, and long pants and long-sleeves. This type of protection may be necessary for people who must work in areas where mosquitoes are present.
- Repellent - Apply mosquito repellent to bare skin and clothing.
- Always use repellents according to the label. Repellents with DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol, and IR3535 are effective.
- Use mosquito netting to protect children younger than 2 months old.
Tips on Repellent Use
- Always read label directions carefully for the approved usage before you apply a repellent. Some repellents are not suitable for children.
- Products with concentrations of up to 30 percent DEET (N, N-diethyl-m-toluamide) are generally recommended. Other U.S. Environmental Protection Agency-approved repellents contain picaridin, oil of lemon eucalyptus, para-menthane-diol, or IR3535. These products are generally available at local pharmacies. Look for active ingredients to be listed on the product label.
- Apply insect repellent to exposed skin, or onto clothing, but not under clothing.
- In protecting children, read label instructions to be sure the repellent is age-appropriate. According to the Centers for Disease Control and Prevention (CDC), mosquito repellents containing oil of lemon eucalyptus should not be used on children under the age of three years. DEET is not recommended on children younger than two months old.
- Avoid applying repellents to the hands of children. Adults should apply repellent first to their own hands and then transfer it to the child’s skin and clothing.
- If additional protection is necessary, apply a permethrin repellent directly to your clothing. Again, always follow the manufacturer’s directions.
COVER doors and windows with screens to keep mosquitoes out of your house.
- Repair broken screening on windows, doors, porches, and patios.

The Department of Health continues to conduct statewide surveillance for mosquito-borne illnesses, including West Nile virus infections, Eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya and dengue. Residents of Florida are encouraged to report dead birds via the Florida Fish and Wildlife Conservation Commission’s site - http://legacy.myfwc.com/bird/default.asp.
