After West Nile Virus Detected, Anne Arundel County to Spray in Affected Areas This Weekend

The Anne Arundel County Department of Health announced that mosquitoes trapped in two parts of the county on July 11, 2023, have tested positive for West Nile virus. These results represent the first West Nile virus-positive mosquitoes identified in the county this year. At this time, no human cases have been reported in Anne Arundel County.

NOTE: The event below, Arts Alive 25, was held on September 8, 2023.

The Maryland Department of Agriculture will spray a solution in the areas where the mosquitos pools were identified.  The department’s Mosquito Control Program will use a permethrin-based solution that the U.S. Environmental Protection Agency has approved for use in public health mosquito control programs without posing unreasonable risks to human health. Out of an abundance of caution, the Maryland Department of Agriculture recommends avoiding outdoor activities during spraying.

Spraying is scheduled for Sunday, July 23, 2023, after 7:30 p.m. near the areas where the mosquito pools were identified. Those areas are near the intersection of Crain Highway and Davidsonville Road.  Communities in the affected area include Amberfield, Lake Louise, and the Northwest Crofton Community District.  Questions about spraying should be directed to the Maryland Department of Agriculture or call the Mosquito Control Program at 410-841-5870.

West Nile virus is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.

Most people exposed to the virus don’t get sick, but about 20 percent develop symptoms like headache, fever, muscle and joint aches, nausea, and fatigue. The current warm weather and high humidity are ideal for mosquito activity and West Nile virus transmission. The Anne Arundel County Department of Health reminds residents to protect themselves from mosquito bites and mosquito-borne diseases.

To reduce the risk of being bitten by mosquitoes, residents should:

  • Minimize time spent outdoors between dusk and dawn when mosquitoes are most active.
  • Be sure door and window screens are tight-fitting and in good repair.
  • Wear long sleeves and pants. Create a barrier to mosquito bites by covering up.
  • Remove standing water. Emptying out water that collects in toys, tires, trash cans, buckets, clogged rain gutters and plant pots will prevent mosquitoes a place to lay their eggs and reproduce.
  • Keep all swimming pools chlorinated and filtered. Backyard ponds should include fish to control mosquito larvae.
  • Consider using EPA-registered repellent such as those containing DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone.
  • Use mosquito netting when sleeping outdoors or in an unscreened structure and to protect infants when outdoors.
