Derry to spray for mosquitoes

September busiest month for West Nile, EEE activity

It’s still early, but New Hampshire appears poised for a typical season for mosquito-borne viruses.

Derry is spraying to control mosquito populations in advance of Labor Day, the seasonal midway point for Eastern equine encephalitis and West Nile virus.

Garrett Simonsen, coordinator for the Greater Derry Public Health Network, announced the spraying yesterday. It is scheduled for Friday evening.

Dragon Mosquito Control will conduct the spraying, which it previously did in Londonderry, Sandown, Newton and Kingston.

“The season is typical of what we’ve expected,” company owner Sarah MacGregor said.

New Hampshire is in the middle of the season, which could last into October, MacGregor said.

“September is the busiest month for disease activity,” she said.

Weather conditions are helping to contain the mosquito population.

“The mosquito population has been on the decline because we haven’t had rain,” she said.

West Nile has a foothold in Southern New Hampshire in Sandown and Pelham, test results through last Friday showed, the state Department of Health and Human Services reported.

EEE has yet to show up in the 12 towns in the region, but has been found in mosquitoes trapped in nearby Exeter and Manchester.

West Nile was found in mosquito batches in Southern New Hampshire, but no animals or humans have tested positive for exposure.

Simonsen said spraying was scheduled in Derry because mosquito batches had tested positive in neighboring towns.

The spraying is slated from 5 to 10 p.m. Friday.

Locations include Barka School, Derry Village School, East Derry School, Grinnell School, Hood School, South Range School, West Running Brook School, Alexander-Carr Park, Don Ball Park, MacGregor Park, Rider Fields, Veterans Field, Pinkerton Academy and the Pinkerton practice field.

Athletic fields will be clsoed from 5 p.m. Friday until 5 a.m. Saturday because of the spraying.
