State environmental officials say they have found no West Nile virus in the latest batch of mosquitoes tested in Rhode Island.
The Department of Environmental Management said Tuesday that all 149 mosquito samples from 29 traps set statewide during the week of June 30 came back negative for West Nile and eastern equine encephalitis.
Results are pending at the state health department laboratory for 144 mosquito pools collected on July 7.
Neither disease has been found in mosquitoes in the state yet this season.
Officials say the best prevention against mosquito-borne illness is preventing bites. Residents are urged to use mosquito repellent, use screens on their windows and doors and eliminate areas of standing water, where mosquitoes breed.
