Guard Against Mosquitoes: Personal Protection is Best
Recent storms and increased summer temperatures have created excellent breeding conditions for mosquitoes. With increased mosquitoes in our area, there is typically an increase in mosquitoes that test positive for West Nile virus (WNV). Each summer, we work with the Ohio Department of Health to trap and test mosquito samples from throughout the county.

So far in 2025, there have been several mosquito samples that have tested positive for WNV. No human cases have been identified. We want to remind everyone that personal protection is best when it comes to preventing mosquito bites. Here are some important reminders:
- Insect repellent – When outdoors, use repellents containing DEET, picaridin, IR3535, para menthane-diol, or oil of lemon eucalyptus. Follow the directions on the package.
- Protective clothing – Wearing lightweight and light-colored pants and full arm shirts can help prevent mosquito bites.
- Avoid peak hours – Mosquitos are most active in the mornings, late afternoon, and evenings. Limiting outdoor activity during these times may help avoid mosquito bites.
- Screens and netting – Make sure you have good screens on your windows and doors to keep mosquitoes out.
- Remove mosquito breeding sites around your home – Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets, and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children’s wading pools empty and on its side when not in use.
