Report prepared by: Wayne N. Andrews, M.S., Priscilla Matton, M.S 

If you have a mission statement, please include it here: 

In conjunction with the belief that mosquito control is an important public health issue, 

the Bristol County Mosquito Control Project, under the guidance of the State 

Reclamation and Mosquito Control Board, strives to serve their membership 

communities by suppressing both nuisance and disease carrying mosquito populations. 

Our goal is to bring mosquito populations to tolerable levels using a variety of 

scientifically effective methodologies consistent with applicable laws. Surveillance, 

water management, biological and chemical controls are performed in an 

environmentally sensitive manner to minimize potential effects on people, wildlife and 

the environment. 

It is acknowledged that commissioners live or work in the county and that all decisions 

be made in a fiscally responsible manner. The Project advocates public outreach and 

education through cooperative efforts with local officials, school departments and the 

news media.

INTEGRATED PEST MANAGEMENT (IPM): 

DEFINITION: a comprehensive strategy of pest control whose major objective is 

to achieve desired levels of pest control in an environmentally responsible 

manner by combining multiple pest control measures to reduce the need for 

reliance on chemical pesticides; more specifically, a combination of pest controls 

which addresses conditions that support pests and may include, but is not 

limited to, the use of monitoring techniques to determine immediate and ongoing 

need for pest control, increased sanitation, physical barrier methods, the use of 

natural pest enemies and a judicious use of lowest risk pesticides when 

necessary. 

Please check off all of the services that you currently provide to your member cities and 

towns as part of your IPM program; details of these services are in the next sections.

*Please attach a link to maps of ditch maintenance areas if possible.

OPEN MARSH WATER MANAGEMENT

support mosquito larval development. 

Please give an estimate of total square feet or acreage: None 

What time frame during the year is this method employed? See Timeline at the end of 

the document.

Please describe the purpose of this program: There are two reasons to do surveillance: 

to monitor mosquito populations and virus levels in these mosquitoes. We work in 

conjunction with the MA Department of Public Health for testing of samples that are 

collected. This helps us monitor the EEE and WNV activity in the local mosquito 

populations. With this information we make application, public outreach and water 

management decisions. Participate in an annual collection survey for Cs. melanura with 

MA DPH, to estimate the population and risk of EEE.

Do you maintain long-term trap sites in any of your areas? Yes 

If yes, please describe how you chose these long-term sites. Originally based on EEE 

human cases in these areas.

 Other Please list: Highlands J 

Did the above listed diseases cause human or horse illnesses? Yes 
Please explain: We have had more EEE activity in our County in the last 5 years or 50 

years then any other mosquito control program in the US. We have collected over 100 

isolations from both WNV and EEE in the past 5 years. We had 6 repoted WNV human 

cases and 2 EEE human cases. 

2008 Horse case- Freetown 

At what arbovirus risk level did the year begin in your area? (If more than one please 

list) 

WNV: 2 

EEE: 2 

At what arbovirus risk level did the year end in your area? (If more than one please list) 

WNV: 4

EEE: 4- New Bedford, Acushnet, Freetown, Berkley 

3- Raynham, Taunton, Dighton, Somerset, Fall River, Dartmouth 

What time frame during the year is this method employed? See Timeline at the end of 

the document.

Comments: Several towns were in risk category 4 for both EEE and WNV. We met 

DPH guildlines for Risk Category 5 in New Bedford but the level was never changed. 

This may be related to the late season activity, however we did have sustained EEE 

isolations from Oc. canadensis, a human biting mosquito and a horse case in the area.

SPECIAL PROJECTS 

Do you perform any inspectional services such as inspections at sewage treatment 

facilities or review sub division plans? Yes 

If yes, please elaborate Perform entomological work when requested by member towns.

Do you work with DPW departments or other local or state officials to address 

stormwater systems, clogged culverts or other areas that you have identified as manmade mosquito problem areas? Yes 

If yes, please elaborate: Extensive work is done with member towns and local 

governmental agencies.

CHILDREN AND FAMILIES PROTECTION ACT 

Is your program impacted by the Children and Families Protection Act? Yes 

If yes, please explain: We have 265 day cares and 150 locations of private, parochial 

and public school properties. 

If you have data on compliance with this Act and your program, please list here: Most of 

our schools have an IPM plan on file with the state, however less than 50% contain any 

mosquito control language. Only schools and daycares the request larviciding or 

adulticiding from Bristol County Mosquito Control have the proper compliance language. 

If you had difficulties with implementation of your program due to this law, please 

elaborate here: Avoiding this many locations at night makes adulticiding applications 

very difficult. 

Comments: Map included at end of document with schools and no-sprays.
