Residents urged to take precautions against mosquitoes

CUMBERLAND – As another round of aerial spraying for mosquitoes took place this week, state officials were urging residents to take precautions against the “critical risk” posed by the Eastern Equine Encephalitis (EEE) these bugs carry.

Spraying for adult mosquitoes in the marshy areas of Cumberland and elsewhere happened Sunday while points further north, including Woonsocket, North Smithfield and Burrillville, continued Monday night. The work was not completed Sunday due to falling temperatures, as spraying is most effective when temperatures are above 58 degrees.

EEE is a rare but serious illness that spreads when people are bitten by infected mosquitoes. On Aug. 30, the Rhode Island Department of Health announced the state's first human case of EEE since 2010 in a person in their 50s from West Warwick. At that time, it was announced that the individual was in critical condition, and has since died. This was Rhode Island's first fatal human EEE case since 2007.

Two mosquito detections of EEE have occurred in Central Falls and two have occurred in Westerly, according to the Rhode Island Department of Health. A horse was also diagnosed with EEE in Westerly. In addition, several EEE cases and positive mosquitoes have been detected in Connecticut and Massachusetts, some in areas that border Rhode Island. Generally, spraying in Rhode Island is occurring in four-mile radiuses around positive samples and cases.

The pesticide that is being applied, Anvil 10+10, is being used at very low concentrations. Spraying is not occurring over fish hatcheries, certified organic farms, surface drinking water supplies, and other open water bodies and coastal areas, states a release.

The product being sprayed is being used at very low concentrations. No adverse health risks are expected with its use for mosquito control. Nonetheless, while spraying is occurring, it is best to err on the side of caution and limit time outdoors and keep windows closed. It is generally good for people to limit their exposure to pesticides.

Personal mosquito prevention measures, including bug spray and eliminating breeding grounds, remain everyone's first defense against mosquito-borne illnesses, such as EEE, according to state officials. All Rhode Islanders are urged to continue taking these measures until the first hard frost of the year, which typically happens sometime in the middle of October or somewhat later.


We have fogging trucks here where I live, that go street to street, at dusk, and they spray on a reg basis every year.....we rarely see any mosquitoes as a result in our residential areas. I wonder if the truck method is better than aerial at low dose.....?
