Baltimore County is conducting mosquito sprayings this week in Catonsville and next week in Pikesville in the wake of two human cases of West Nile Virus being discovered in the county.
Officials said spraying would take place after 7:30 p.m. and residents in those areas should stay indoors during spraying to minimize direct contact with the spray. Spraying will be conducted using Maryland Department of Agriculture spray trucks.
The material being used, Biomist 30-30, contains the active ingredient permethrin, and is approved by the U.S. Environmental Protection Agency, officials said.
Catonsville and Pikesville are the only two areas of the county scheduled for sprayings, but officials are reminding residents they can take precautions to help curb the population of mosquitoes — which can carry West Nile Virus. Measures include:
• Using EPA-registered repellents.
• Avoiding unnecessary outdoor activities at dawn and dusk when mosquitoes are most active.
• Wearing long pants, long-sleeved shirts and hats when outdoors.
• Draining areas of standing water.
• Repairing damaged window screens.
County health department officials noted that mosquitoes can carry a number of diseases, including West Nile Virus — a disease that is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected animal.
In humans, West Nile generally causes either no symptoms, or mild, flu-like illness. However, it can also be fatal in some cases.
