In the wake of last week's discovery of West Nile virus in North Andover, town officials have decided to have certain areas sprayed with pesticides Tuesday evening.
Crews will spray the area around the Division of Public Works, where the West Nile mosquitoes were found, North Andover Board of Health Chair Thomas Twowbridge said. The spraying will be from dusk until midnight.
West Nile was discovered in two samplings of mosquitoes last week and has been found in several nearby communities recently.
"The mosquito testing will be increased to look for further risk and any need for treatment," Trowbridge said.
