After a local pool of mosquitoes turned up positive for Eastern equine encephalitis last week, town officials are again urging residents to take precautions to avoid the insect.

According to David Poulson, Windham’s transfer station manager and health officer, town officials learned about the positive test on Sept. 22. Officials did not immediately release the exact location where the infected mosquito was found, but Poulson said it was important for residents across town to take steps to avoid contracting EEE.

According to Poulson, not knowing whether the mosquito carrying EEE was native to that particular spot or had flown in from another region added to his hesitancy to release the particular location where the pool was taken from.

“Mosquitoes have no boundaries ... Say you’ve had a positive hit in ‘Area A.’ That doesn’t mean those mosquitoes are never going to leave that area. You can’t (assume) that those mosquitoes are going to stay at a specific spot. Those mosquitoes could travel anywhere within a certain area in Windham,” he said.

Those precautions include wearing protective clothing, using insect repellent, eliminating standing water and avoiding spending time outdoors at dusk or dawn, according to an informational flier public officials released to residents on the town’s Web site earlier this week.

Poulson said the town did not plan to take any emergency mosquito control action in the wake of the positive test result. The community’s agent, Swamp Inc., sprayed the town’s athletic and recreational fields for the pest after Rockingham County fell under a state public health threat for EEE earlier this month.

The spray is considered effective for two weeks to a month and officials hope colder weather in October will eliminate the problem before more action is needed, said Poulson. According to state officials, more 3,000 pools have been tested for EEE statewide this season, with 53 coming up with a positive identification. One human case has been reported in Candia, officials said.
