The City of Upper Arlington contracts with Franklin County Public Health for an integrated mosquito management program. This includes testing and treatment for disease mosquitoes as well as trapping and treatment for floodwater/nuisance mosquitoes. The combined efforts of the City, the Upper Arlington Board of Health, Franklin County Public Health (FCPH) and residents are key to reducing populations.
FCPH focuses on taking action in areas with large mosquito populations or a high incidence of mosquitoes testing positive for diseases such as West Nile Virus (WNV) and Encephalitis. It is hoped these efforts can break the disease cycle. Read on for an outline of the prevention program.
Identifying and Eliminating Breeding Sites
The safest, most cost-effective way to control mosquitoes is to eliminate breeding sites. City and FCPH staff work to identify and eliminate breeding sites, using a variety of tools. Adult surveillance is conducted by trapping adult mosquitoes using light, gravid or sentinel traps at various locations. You can help in this process by contacting FCPH if you know of low-lying areas that collect stagnant water.
Determining the Need to Use Adulticide
The decision to use adulticide is based on the percentage of a mosquito pool testing positive for disease; and is considered the last line of defense if other practices have failed. If spraying is necessary, the City typically receives 24-48 hour notice of any areas to be treated, and uses the ALERT Franklin County automated notification system and UA Alerts texting system to inform affected residents. However, given the tight time constraints, it is recommended that residents concerned about mosquito spraying check the City’s website and Facebook page for the most up-to-date information.
FCPH also posts details of all Franklin County areas to be sprayed – along with precautions to take after your area has been sprayed – on its website which can be accessed via the link below.
Adulticide Product
FCPH uses Merus 3.0, a natural botanical pyrethrin derived from chrysanthemum flowers. Merus 3.0 is listed with the Organic Materials Review Institute and can be applied in and around organic gardens. FCPH uses ultra-low-volume spray machines that are calibrated to apply extremely small amounts of pesticide over large areas, which is lethal to mosquitoes but will not adversely affect other insects.
Do Not Spray
If you do not want your home sprayed, you must fill out a Do Not Spray form annually, which you can complete by clicking the link below and filling out a form on the Franklin County Public Health’s website. This request will take effect five business days after its receipt.
Help Eliminate Mosquitoes in Your Yard
- Empty, remove, cover, or turn over receptacles with the potential to hold water.
- Clean bird baths twice weekly.
- Discard old tires or store them indoors.
- Repair leaky plumbing and outside faucets.
- Make sure gutters and downspouts are free of blockage and are properly draining.
- Fill holes in trees with sand.
- Empty your pets’ water dishes daily.
- Drain or fill low areas on your property that hold water for more than three days.
Ways to Reduce Mosquito Bites
- Wear light-colored clothing, long-sleeved shirts or jackets and long slacks.
- Avoid mosquito-infested areas or stay indoors at dawn and dusk when mosquitoes are most active
- Avoid physical exertion and use colognes and perfumes sparingly, as these may attract mosquitoes.
- Use mosquito repellent, according to directions, when you are outdoors. Click the links for more information about mosquito repellent from the CDC and EPA.
- You can also use products containing picaridin or oil of lemon eucalyptus or Para-menthane-diol as repellents. These products typically provide longer-lasting protection.
