Broward County's Mosquito Control will spray in the southwest part of the county from 4 to 6:30 a.m. Friday.
The area to be sprayed includes Griffin Road to the north, Johnson Street to the south, Interstate 75 to the east and U.S. Highway 27 to the west. It includes the cities of Southwest Ranches and parts of Pembroke Pines and Davie.
Residents with breathing difficulties should remain indoors during the spraying.
Recent heavy rains and the return of summer temperatures prompted the need for spraying due to the increase in mosquitoes.
