If you heard or saw planes flying over your house at a low altitude over the weekend, you were likely hearing the state's round of aerial spraying to help prevent Eastern Equine Encephalitis.

Seven communities in Massachusetts had been sprayed as of Sunday, the Massachusetts Department of Public Health announced. Fourteen remaining communities are still to be completed after low temperature conditions forced the state to cease early Saturday.

Communities that still need to be sprayed include: Acushnet, Bridgewater, Carver, East Bridgewater, Freetown, Halifax, Hanson, Kingston, Lakeville, Middleborough, Pembroke, Plympton, Rochester, and West Bridgewater.

Norton and its neighbors in Berkley, Dighton Easton, Raynham, Rehoboth and Taunton had been completed.

The state announced it would spray last week after a second round of EEE-infected mosquitoes were found in Easton.The DPH expanded its plans for spraying from 10 towns to 20 towns when samples continued to be found in Easton and surrounding communities.

Last year, a Raynham man died of the virus resulting in a public outcry for aerial spraying earlier in the season. The first EEE-infected mosquitoes were found July 8 in Easton.
