City to Begin 2020 Mosquito Control Program Starting June 3

Post Date:05/26/2020 10:00 PM

The City of Williamsburg 2020 mosquito control program will begin Wednesday, June 3, 2020. The program protects the public’s health by reducing the number of mosquitoes during the mosquito season June through September. Mosquitoes are a nuisance and regarded as an infectious disease vector for pathogens such as West Nile Virus, Eastern Equine Encephalitis and Zika.

The City’s mosquito program includes the spraying of City streets on Wednesdays beginning the route around dusk from June through September. Spraying is weather-dependent and curtailed during rainy conditions.

The City uses an insecticide that kills adult mosquitoes, black flies and gnats. The insecticide, Duet, rapidly bio-degrades to create less risk for area beekeepers and pollinators.

The program also includes on-site yard inspections, eliminating breeding sites such as standing water and using a low-toxicity pellet or briquette style pesticide to reduce larvae when removing standing water is not feasible. Most species of mosquito live about two weeks, so any change in their breeding grounds will have a near-immediate impact on the number of mosquitoes in an area.

Every Williamsburg resident can help fight nuisance insects by getting rid of standing water in their yard:

1. Change the water in birdbaths, ornamental ponds and fountains at least once a week.

2. Clean leaf-filled drains, gutters and roof areas to allow proper drainage.

3. Fill in or drain any low places (puddles, ruts) in yard.

4. Keep grass cut short and shrubbery well-trimmed around the house so adult mosquitoes will not have a place to hide.

5. Make sure your backyard pool is properly cared for while on vacation.

6. Turn buckets, baby pools, boats and other outside containers upside down when they are not in use.

7. Cover rain barrels, garbage cans and other large containers.

8. Properly dispose of old, unnecessary tires.

9. Repair leaky water faucets, water hoses and air conditioners.

Call the Public Works office at 757-220-6140 with any questions about the mosquito control program, for an on-site yard inspection or for information on how to get rid of old tires.
