DELAWARE, OH. – The Delaware General Health District is informing residents in Marlboro Township and the village of Radnor that mosquito fogging will occur Monday Sept. 18 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:

Radnor: north of Gallant Road, south of Watkins Road, west of Hedley Road and east of River Road.

Marlboro Township: directly south of the Delaware County line, west of Delaware Lake Reservoir and east of Section Line Road.

In addition, fogging was canceled Wednesday because of the continued rain. Fogging will resume this evening (Sept. 14) in Harlem, Kingston and Scioto Townships as well as the village of Ostrander after traps this week also tested positive for West Nile virus.

Exact fogging zones are located on the mosquito 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 repellent that contains DEET or Picaridin.
