  • Delaware General Health District Press Release

DELAWARE, Oh. – The Delaware General Health District is informing residents in Genoa Township and the city of Delaware that mosquito fogging will occur Tuesday Sept. 19 as a result of collection traps testing positive for West Nile virus.
Weather permitting, the Heath District’s Residential Services Unit will fog in the following areas:
Genoa: north of Hilmar Drive, south of Lewis Center Road, west of Hoover Reservoir and east of Worthington Road.

Delaware City: west of U.S. Highway 23

Exact fogging zones are located on the Animals & Insects page of Updated fogging plans will be announced on and on the Health District’s Facebook and Twitter pages.

Any resident who does not want their property sprayed is asked to call the Health District at 740-368-1700 and request to be placed on the no-fog list.

All residents are urged to protect themselves from mosquito bites. The most effective prevention is to dump standing water where mosquitoes breed. Make sure your property is free of stagnant water in flower pots, bird baths, tarps, gutters and other places where it can collect. Avoid going outdoors in the morning and the evening when mosquitoes are most active. If you do go out, wear light-colored, long-sleeved clothing and apply mosquito repellant that contains DEET or Picaridin.

    Please make sure to post a map (“west of U.S. Highway 23” is a very large area), scheduled timing, and the pesticide used to make sure residents are informed and can take appropriate actions.

    Just called, and here’s some details that may help others (and will hopefully reduce additional calls to them as well):

    – Pesticide to be used is Kontrol 4-4, administered via a vehicle with a fogger on the back.

    – Range is approximately 150ft from the source of the fogger as it drives.

    – Precautions will be taken to keep it out of the river wherever possible (since Kontrol 4-4 has a large impact on all fish).

    – Honey bees exposed to the fog may be severely impacted.

    – Scheduled fogging will start at 8pm this evening (Sept. 19, 2017), but could be postponed if it rains.

    – It is advisable to keep all windows closed while the fogging is taking place.
