Ground Larvicide Notice
Please be advised that the Norfolk County Mosquito Control Project will begin the larval control program beginning in April 2008. This program will be a continuation of the procedure, which has been used in past years. The Norfolk County Mosquito Control Project will be conducting larval control applications using a granular form of Bti (Bacillus thuringiensis israelensis), a naturally occurring soil bacterium that kills mosquito larvae in low-lying swampy areas where mosquito larvae develop throughout the season.
Aerial Larvicide Notice
The Norfolk County Mosquito Control Project
will be treating wetlands in 25 of the communities within the District with a
granular form of Bti (Bacillus thuringiensis israelensis),
a naturally occurring soil bacterium that kills mosquito larvae before they
become adult mosquitoes. Typically this
takes place in mid to late April depending on the develop
Bti is virtually non-toxic to humans, plants and
animals. The Bti is impregnated on coarsely ground
corncob granules. In the larger wetlands which are inaccessible from roads,
these applications will be done by helicopters flying at tree top level. The
granules when applied fall straight into the wetland and do not drift beyond
the targeted area.
Aerial Bti
applications will only be done in wetlands that potentially harbor significant
numbers of mosquito larvae. In early March the Project will begin taking
"dip" samples of water from these wetlands in order to determine
larval density. The Project will follow up with aerial/ground applications
where sufficient mosquito larvae density has been identified. Aerial
applications of Bti are currently scheduled to take
place so
According to information on the EPA website, http://www.epa.gov/pesticides/health/mosquitoes/larvicides4mosquitoes.htm ...microbial larvicides
"...are essentially nontoxic to humans, so there are no concerns for human
health effects with Bti..." and "...do not
pose risks to wildlife, most non-target species, or the environ
We remind you that, since the mosquito species
most likely to be potential vectors of West Nile Virus develop in containers
such as rain gutters, kiddie pools, or any other
containers which hold water for more than five days. The public can play a
major role in controlling these vectors by eliminating all standing water on
their property
Residents not wishing to have their property treated
must notify the Town Clerk in writing, with a copy to the Norfolk County
Mosquito Control Project.
Note: The Norfolk County Mosquito Control Project will issue an additional notice in May before early morning residential ULV applications commence.
A Copy of the Legal Notice will be posted in the Boston Globe in February 2008:
The
Norfolk County Mosquito Control Project will be conducting
helicopter applications of the biological larvicide Bti to control
mosquito larvae. The application will be
conducted over specific large
wetlands in the Towns of:
Avon/Bellingham/Braintree/Canton/Dedham/Dover/Foxboro/Franklin/
Holbrook/Medfield/Medway/Millis/Milton/Needham/Norfolk/Norwood/
Plainville/Quincy/Randolph/Sharon/Stoughton/Walpole/Westwood/
Weymouth/Wrentham area.
The
application will be conducted between April 1, 2008 and September 15, 2008.
