Board of Health issues mosquito advisory

Aug 5, 2019

As the state has raised the risk level for mosquito-bourne disease in neighboring South Coast communities, Dartmouth town officials are advising residents to stay alert and be careful.

On July 31, the state Department of Public Health issued a “High Risk” advisory for eastern equine encephalitis (EEE) in seven southeastern Massachusetts communities, including New Bedford. 

In Dartmouth, the risk level is currently “Moderate” after mosquitoes carrying EEE were found near the northeastern section of Dartmouth.

The Dartmouth Board of Health is advising residents to stay informed and updated about EEE activity.

According to the board, residents should avoid being outdoors between peak mosquito hours -- dusk to dawn -- or use bug spray and wear long-sleeved shirts, long pants, and socks when outdoors.

Residents should use bug spray when going outdoors. Ideal bug sprays include DEET, permethrin,  picaridin, or oil of lemon eucalyptus. 

DEET products should not be used on infants under two months of age, and should be used in concentrations of 30 percent or less on older children. Permethrin should only be applied to clothing items, shoes, bed nets, and camping gear, not skin.

Homeowners can reduce mosquito populations by draining standing water where mosquitoes lay eggs, install or repair screens to keep mosquitoes outside, and check window-mounted air conditioners to make sure mosquitoes can't enter it.
