The city of Grand Prairie will spray for mosquitoes in two areas where human cases of Zika and West Nile virus infections have been confirmed.
The Zika infection occurred during travel in other areas, the city said in a statement Saturday.
Officials have set a four-night window — from Saturday through Tuesday — during which they plan to spray on two nights, weather permitting. Spraying starts at 9 each night unless it rains or winds exceed 10 mph.
One spray area is bounded by Excalibur Drive on the north, Kingswood Boulevard and Lynn Road on the west, Red Oak Drive on the south and Tarragon Lane on the east.
The second is bounded by Atrium Drive and Forum Drive on the north, Daisy Lane on the west, Paladium Drive on the north and Colosseum Way on the east.
Officials advise residents in those areas to keep themselves and pets indoors and cover fish ponds during spraying.
The statement urged residents to follow common health guidelines for fighting mosquitoes: Empty or eliminate tires, pots and any other receptacles that can hold water, which invites mosquitoes to breed, and use insect repellents containing DEET to prevent mosquito bites.
The city website has maps on the targeted spraying areas.
