Chelmsford To Spray For Mosquitoes

CHELMSFORD, MA — If you hear a helicopter overhead Wednesday and wonder what's happening, it's the annual larvicide program to cut down on the number of mosquitoes in the area.

Each spring for the past 15 years the Central Mass Mosquito Control Project uses a helicopter to drop pellets in wetland and ponding areas in Chelmsford in an effort to reduce mosquitoes in May and June.

The group uses a product called Bacillus thuringiensis israelensis, a natural bacteria that is certified organic and is non-toxic to humans, pets and other wildlife, according to an announcement.

Although it's generally safe for humans, the project advises that people who suffer from chemical sensitivities or feel spraying may aggravate a preexisting health condition, should consult their physician and take special measures - such as staying indoors for about 20 minutes around the time of the pellet drop- to avoid exposure if they feel this is necessary.

To reduce mosquito populations around your home and neighborhood, experts say the number one thing to do is get rid of any standing water that is available for mosquito breeding. Mosquitoes will breed in any puddle or standing water that lasts for more than four days.
