BALTIMORE (WJZ) — The first of two planned mosquito spraying has occurred in the Milford area to suppress the transmission of West Nile Virus, where a human case was identified.

Weather-permitting, the Maryland Department of Agriculture will conduct the second spraying, which will include streets, on Thursday after 7:30 p.m.

The Sudbrook Community Association requested that the Sudbrook Park area not be sprayed.

However, the Ralston Community Association requested that more of their community streets, which were not in the planned spray zone, be included in Thursday’s spraying.

MDA recommends that residents in the affected area stay indoors during spraying.

Mosquitoes can carry a number of diseases, including West Nile Virus, which is still present in the Baltimore area.

The disease is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected animal. Humans that contract West Nile generally do not have any symptoms, or have mild, flu-like illnesses, but the virus can also be deadly.

You can help reduce the number of mosquitoes in areas outdoors by draining sources of standing water, which will cut down on places where mosquitoes can lay their eggs and breed.
