Board Of Health Update 10/23/19

Re: Mosquito Control 


Happy Halloween and Remember to Trick-or-Treat (and put on DEET)

& North Andover Public Schools Outdoor Activities and Athletics.


The Board of Health has not recommended any restrictions on outdoor activities after 6:30 p.m. because of cooler temperatures and reduced mosquito activity at night as of October 26, 2019. The Board of Selectmen has set Trick-or-Treating Hours for October 31, from 5:30-7:30 p.m.  North Andover High School will be releasing information about changes to sports, programming or other activities. Please see the NAHS Athletic Schedule site for additional information.


Mosquito activity has been declining with the cooler temperatures at dusk, and mosquitoes are completely inactive when it is 50 degrees or below. There may still be some limited mosquito activity, and residents should still take precautions as necessary.  North Andover is still listed at a moderate risk (not high or critical) because we have not had a hard frost, but the cooler temperatures during peak mosquito hours have reduced mosquito activity and the threat of mosquito-borne diseases.  


Mosquito-borne diseases are completely preventable, and awareness and personal protection are always essential.  The Board of Health still recommends that residents be aware and continue using bug spray, wearing appropriate clothing to cover exposed skin and to always be aware of any mosquito activity when outdoors.  Mosquitoes may still be active during the warmer daytime hours in certain areas such as in the woods, along trails and in shaded areas so please be aware and take all necessary precautions to avoid mosquito bites.  Have a happy, mosquito-free Halloween and remember to Trick-or-Treat and put on some DEET! Please go to for more information.

 If you have any questions or concerns, please feel free to call the North Andover Public Health Department at 978-688-9540.
