The city of Marysville wants to share the latest buzz about mosquito spraying.

The city of Marysville wants to share the latest buzz about mosquito spraying.

Workers treated the Jim Simmons Trail as well as Mill Creek, Greenwood, Aldersgate, McCarthy and American Legion parks June 12-13.

Public Service Director Mike Andrako said the spraying schedule is based on weather.

"We may spray as frequently as every other week (depending) on how much rain we get," Andrako said in an email. "During the summer, we will spray at least monthly."

Andrako said residents can expect more spraying around July 12, if not sooner.

"We may do the Jim Simmons Trail (again) in the next week. We also may treat parks before some upcoming events," he said.

WBNS-10TV meteorologist Mike Davis said June has definitely been a rainy month.

Davis said according to the National Oceanic and Atmospheric Administration, monthly rainfall for Columbus totaled 4.68 inches as of Friday, June 27. (Marysville-specific numbers are not available since neither the NOAA nor the National Weather Service has a local office.)

Marysville typically budgets $5,000 a year for mosquito spraying. It uses a vehicle-mounted ultra-low-volume fogger. The spray lands on vegetation and acts as a barrier to mosquitoes and other insects.

"The spray is not considered hazardous to people, although we try to treat areas during dawn or dusk when possible to avoid people on the trails and to get mosquitoes when they are most active," Andrako said.

A major concern is mosquito-borne illnesses such as West Nile virus. According to disease maps from the U.S. Department of the Interior/U.S. Geological Survey, as of Thursday, June 26, there were no cases of West Nile virus in Ohio so far this year.

Last year, there were 24 cases statewide. Union County had one and Franklin County had two. The first case was not reported until August, and numbers peaked in September. In 2012, there were 121 cases in Ohio -- none in Union County.

Andrako said the city does not set mosquito traps to test for West Nile virus, but as the insect population increases, so does the risk of infection.

"The city encourages people to take precautions by reducing standing water on their property and using bug spray when necessary," he said.

The Union County Health Department performs limited checks of the mosquito population, trapping and sending some to the Ohio Department of Agriculture to test for West Nile virus, according to the health department's website.

The health department suggest these steps to prevent mosquito bites:

* Avoid being outdoors at dawn and dusk, when mosquitoes are most active.

* Wear light colors, long sleeves and long pants in mosquito-infested areas.

* Use a DEET-based insect repellent and follow label instructions.

* When camping or spending time outdoors, consider Permethrin-treated bed nets, tents or clothing.

* Avoid perfume, colognes or other heavy scents that may attract mosquitoes.

To reduce breeding habitats:

* Change water weekly in items such as birdbaths, baby pools and buckets, or store them upside down.

* Fill low areas in yards and provide proper drainage.

* Make sure gutters are clear and drain properly.

* Don't store tires where they can hold water, and make sure tire swings have holes for drainage.

* Fill cavities in trees with soil, sand, or gravel.
