This week Columbus health officials announced two pools of mosquitoes tested positive for West Nile virus.
Last year in Ohio only four cases of West Nile were reported. In fact 80 percent of those with West Nile never develop symptoms.
"The Health Department uses treatment methods the same whether we are in an outbreak or not," said Public Health Sanitarian Matt Hemmer. "We are able to ramp up our treatments if need be, but usually we attempt to cover the county in a pretty even method."
Treatment methods include a truck fogger and larva side sprayer that release an Adulticide to kill mosquitoes. But, when it comes to the pests, the best way to prevent them is to look close to home.
"The most important thing people can do to protect themselves is to look at their own yards, their own properties for any sources of standing water," said Hemmer. "Even small containers of water can be very dangerous and great breeding grounds for mosquitoes."
Hemmer said some items that often contain standing water include birdbaths, kids toys, tires and even gutters. To see a list of what areas have been sprayed visit the health department's website.
Mosquito spraying is funded through the taxpayer passed health department levy.
