A few days after the dangerous bugs were discovered in Haverhill, mosquitoes infected with West Nile Virus have also been detected in nearby Groveland.
An advisory from that town’s Board of Health said the disease-carrying mosquitoes were found in the Barehill Road, Center Street and School Street areas. The advisory said Groveland plans a “targeted spray” tonight of the listed areas and surrounding roads, as well as near Bagnall Elementary School.
West Nile-carrying mosquitoes have been showing up in traps across the region in recent weeks, but no people in northeastern Massachusetts have become ill from the virus yet this year, health officials said.
The Groveland advisory said the Northeast Massachusetts Mosquito Control District will spray the town with a substance called Duet, and that more information is available on the Pentucket Regional website under “announcements.’’
Haverhill has completed its targeted spray of areas were mosquitoes carrying West Nile Virus were detected last week: Behind the animal shelter at the rear of the Highway Department yard on Primrose Street, and on North Avenue, in the area of Frye Pond near the National Grid company gas tanks.
Mayor James Fiorentini said the city’s targeted spraying concluded Tuesday night, and that citywide spraying will take place in the coming days. He said those dates will be announced prior to more spraying.
Haverhill’s spraying takes place from the back of trucks and uses the standard Anvil 10+10 solution.
Fiorentini said the mosquito control district characterizes the appearance of West Nile in communities on a scale of 0 to 4. He said Haverhill is at level 2.
“We’re at a moderate level that suggests we should take precautions, but not panic,” he said. “Experts recommend that we spray the non-toxic solution in the area where these mosquitoes were identified ... to protect our citizens.”
