It’s Mosquito Season

The City of Gahanna has contracted with Franklin County Public Health (FCPH) for mosquito control.  FCPH uses an Integrated Pest Management approach with a public health focus to reduce and control disease carrying mosquitoes.  Various tools and techniques are utilized throughout the mosquito season to help control the mosquito population.  These include:

• Larviciding areas of stagnant water and stormwater catch basins to prevent mosquitoes from hatching in these prime breeding sites.
• Surveillance of adult mosquito populations by the use of traps.
• Testing of adult mosquitoes for the presence of disease.
• Adulticiding (spraying) using Ultra Low Volume (ULV) truck mounted equipment to treat residential areas to reduce adult mosquito populations.
• Implementing a variety of educational materials and awareness approaches.

Franklin County Public Health uses the data they collect from these methods along with historical data about mosquito breeding locations, areas that traditionally have high adult mosquito populations and the frequency and distribution of mosquito-borne diseases to concentrate and focus their efforts.  They also rely on residents to report areas that they suspect may be mosquito breeding areas and/or when there is an increase in adult mosquito activity.

Call the FCPH Mosquito Bite Line at 614-525-BITE (2483) to submit a request for service or to report mosquito problems or concerns.  The Bite Line is a voicemail system so please leave a detailed message.  All submissions will be processed in the order received.  FCPH will make an attempt to respond to reported mosquito problems or concerns within one business day.  This may include a site visit to the location reported and/or telephone call to try and obtain further information.

Testing and Spraying
During mosquito season, FCPH will set traps out every Monday night throughout central Ohio and test the mosquitoes on Tuesday for mosquito-borne diseases, such as the West Nile Virus.  The criteria for spaying is based on an increase of mosquitoes trapped and/or if mosquitoes test positive for West Nile Virus.  Click here to view the weekly trap data.  If there is a need to treat a specific area in Gahanna, pre-spray maps will be featured on the City of Gahanna's website prior to treatment.  Click here to view local spray maps.

Did You Know...
• Mosquitoes are not only annoying, but they present a potential health risk as transmitters of diseases such as encephalitis and West Nile Virus.
• Mosquitoes lay their eggs in water.  Standing water is required for their young to hatch and develop.  A single water-filled bucket can produce hundreds of biting mosquitoes in little as one week.
• Most mosquitoes spend their entire lives near their container-breeding site.
• Female mosquitoes look for hosts to bite nearby.
• Dawn and dusk are when mosquitoes are most active.
• While the adult mosquito’s life expectancy is not usually more than a few weeks, the female may lay several batches of eggs each containing several hundred eggs during its life.

What Can You Do?
Mosquitoes are attracted to anything they can get a blood meal from.  Not only are mosquitoes annoying, but they present a potential health risk as transmitters of diseases such as encephalitis and West Nile Virus.  By eliminating potential breeding sites around your home and taking simple precautions, you can lower your chances of getting bit by mosquitoes and avoid mosquito-borne diseases.  Follow the tips below:

Take a few minutes to go outside and look around your yard.  Anything that holds standing water (pots, tarps, trash cans, toys, etc) could be a potential breeding site for mosquitoes.  It does not take much water and it does not take much time.  Dump these containers and turn them upside down or store them inside your garage.
• Change the water in wading pools, planters and bird baths once a week.  Change water in pet dishes daily.  This will prevent the breeding and growth of mosquitoes.
• Clogged gutters are an optimal environment for mosquito eggs.  Ensure your gutters and downspouts are free of blockages and are properly draining to prevent mosquitoes from laying eggs.
• Repair leaky pipes and outside faucets.
• Drain or fill low areas on your property that hold water for more than three days.
• Keep window screens and screened doors in good condition so mosquitoes cannot enter the home.
• Avoid being outdoors at dawn and dusk when mosquitoes are most active.
• When outside, wear light colors, long sleeves, long pants and socks.  Mosquitoes can pierce tight clothing so be sure to wear loose-fitting clothing.
• Use repellent products that contain active ingredients which have been registered with the US Environmental Protection Agency (US EPA).  Products containing DEET and Picaridin typically provide longer-lasting protection than others, but products containing Oil of Lemon Eucalyptus, PMD or IR3535 also provide a reasonable amount protection.  Always follow label directions when applying mosquito repellents and see if it is appropriate to apply to children, as some may have concentrations not suitable for small children.
• Avoid perfume, colognes or other heavy scents that may attract mosquitoes.
