You can control the mosquito population

Mosquitoes are an all too familiar summer nuisance. They are not only annoying, but they present a potential health risk as transmitters of diseases such as West Nile virus and Zika virus. Mosquitoes require standing water for their young to hatch and develop. Once eggs are laid, a new crop of mosquitoes can hatch, grow and emerge from the water as adults in as little as one week. Eliminating potential breeding sites around your home can go a long way to reduce the mosquito population. Many mosquitoes stay very close to their juvenile habitat when they emerge as adults, and the females look for hosts to bite nearby. Eliminating mosquito habitats around your home can prevent bites, reduce your risk of disease and make your summer activities more enjoyable.

Here are a few simple suggestions that can make a big difference in controlling the mosquito population in your own back yard:

  • Empty, remove, cover or turn over any container that has the potential to hold water.
  • Repair leaky pipes and outside faucets.
  • Make sure gutters and downspouts are free of leaves and debris, and are properly draining.
  • Change the water in wading pools weekly and store indoors when not in use.
  • Properly dispose of old tires.
  • Empty planters that hold water twice each week.
  • Empty bird baths weekly.
  • Empty your pets watering dishes daily.
  • Use sand to plug holes in trees where water can collect.
  • Drain or fill low areas on your property that hold water for more than five days.
  • Remind or help neighbors to eliminate breeding sites on their property.

Do Your Part to Prevent West Nile Virus


Franklin County Public Health has been actively trapping mosquitoes since Mid-May to monitor the population and test for West Nile virus (WNV). Through this surveillance, we know there is WNV in our community.


It is not unexpected to see WNV in mosquitoes in our community. WNV has been present for many years and historically begins to show up at this time of the year.  It is a good reminder for residents to take precautionary steps to protect themselves and their families.


  • Wear insect repellant containing DEET (follow package directions)
  • Limit outdoor activity at dusk and dawn when mosquitoes are most active
  • Eliminate all standing water around your home (mosquitoes breed in water and it doesn’t take much)


WNV can be transmitted to people through the bite of an infected mosquito. Symptoms include mild fever, headache and body aches, often with skin rash and swollen lymph glands. Eighty percent of people bitten by an infected mosquito will not show any symptoms at all.  Less than one percent of those who do have symptoms will become severely ill.  Franklin County had one human case of WNV in 2016 and three human cases in 2015.  


Franklin County Public Health will continue their comprehensive mosquito control program throughout the mosquito season.  Fifty Gravid mosquito traps are set weekly throughout the county to trap and identify culex mosquitoes, which have the potential to carry WNV. The mosquitoes in each trap are identified and grouped into pools of fifty.  Based on historical data and/or high trap counts, some mosquito pools are tested for WNV in our facility to give us quick results.  All mosquitoes are sent to the Ohio Department of Health for WNV testing.
