Mosquito Information

Update - September 21, 2018
On Friday, September 21, 2018, the Wenham Board of Health received results that of the mosquitoes collected this week one tested positive for West Nile Virus. The mosquito was collected at the 91 Grapevine Road trap. The trap on Arbor Street had no positive results for WNV and also had no mammal biting mosquitos (only those that bite non-mammals). The Board of Health continues to encourage all residents to take preventative action against mosquito bites through the end of the season (until after the first hard frost which is three consecutive days under 32F degrees) as the State of MA remains at the Moderate risk level. We will will continue to provide updates through the end of mosquito season. 

At this time, mosquito prevention information has been posted at Pingree Park Playground and parking lot; Iron Rail fields and tenant parking; WVIS Tennis Courts and playground; and the Buker fields and playground.

Announcement - September 12, 2018
The Massachusetts Department of Public Health recently announced that West Nile Virus (WNV) has been detected in mosquitoes collected from a site at the Iron Rail property in Wenham. We have had 2 positive tests there over the past 2 weeks. With over 500 positive WNV results to date statewide, all of Massachusetts is now considered a moderate risk level. The Wenham Board of Health met this morning with the Northeast Mosquito Control Board, a state agency that oversees testing and treatment of mosquitos for Essex County. They identified procedures for the Board to follow regarding prevention including increased public education on mosquito bite prevention. The flyer below will be posted at all public playing fields and playgrounds. We also encourage all community organizations and schools to forward these flyers to their constituencies to raise awareness for protection. We have also attached information from the MA Dept of Public Health regarding the safe use of mosquito repellents.

The Board of Health is continuing to monitor the situation and updates will be posted to the home page of the Town website. We encourage you to share the attached flyers with your listserv. Maribeth Ting, the Public Health Nurse, can answer any questions regarding mosquito prevention or West Nile Virus at Questions regarding mosquito testing or Board of Health updates can be directed to Jackie Bresnahan, Permitting Coordinator at or 978-468-5520 ext. 4.
