BOSTON (AP) - State health officials say aerial spraying has cut the mosquito population in half in six southeastern Massachusetts communities.
Department of Public Health Commissioner John Auerbach warned on Wednesday that the results do not eliminate the threat of mosquito-borne illnesses in Massachusetts.
The spraying killed mosquitoes that were in flight during the Aug. 13 operation in Bridgewater, Easton, Norton, Raynham, Taunton, and West Bridgewater. It occurred after officials detected several mosquitoes infected with Eastern Equine Encephalitis in the area.
There has been only one confirmed case of human EEE in Massachusetts this year. Officials say the Metrowest resident may have contracted the disease out of state.
In June the department issued new guidelines that would allow health officials to consider spraying insecticides in a region if just one mammal-biting mosquito is found to be infected with EEE.
