What we do
BPHC partners with the Suffolk County Mosquito Control Project (SCMCP) to protect Boston residents from mosquito-borne disease transmission. The SCMCP collects mosquito samples in traps every week during the summer and early fall. These traps are throughout the city. They test the samples at the Hinton State Laboratory to determine if WNV or EEE virus is present.
Information from mosquito collections helps determine where to put extra precautions to keep Boston residents safe. This may include truck mounted aerosol spraying to control adult mosquito populations.
