Block Island has tested negative for the deadly mosquito-borne virus EEE once again.

Town Manager Ed Roberge informed the Town Council at its meeting Monday night that testing conducted during the week of Sept. 30 - Oct. 4 came back negative. He also noted that officials were hoping for a “killing frost” to eliminate the presence of mosquitoes on the island. Roberge continued to urge the public to take precautions by applying insect repellant, wearing long sleeve clothing and limiting activity outdoors during dusk and dawn.

Al Gettman, coordinator of the Rhode Island Department of Environmental Management's Mosquito Abatement, told The Block Island Times that the "killing frost has not happened yet, so while mosquitoes are dwindling, some risk remains, especially when the temperature exceeds approximately 55 degrees.” 

According to, “A killing frost is defined as two consecutive hours at a temperature below 28 degrees Fahrenheit. A hard or killing frost will kill virtually all exposed mosquitoes.”
