Dear Families & Staff,

I wanted to pass along an update regarding some precautionary measures we are taking with regard to mosquito control and EEE.  We have been in contact with both the Acton and Nashoba (serving Boxborough) Boards of Health about EEE in our towns, most recently this past Saturday.  

As of this morning,  risk levels in our communities are currently listed as “moderate” in Acton and “low” in Boxborough.  The state Department of Human Services provides a helpful website  that includes guidance about how to respond to each risk level:

Specific steps we are taking as a district:

Last week, we began planning to have school district fields sprayed for mosquito control.  We have scheduled Central Massachusetts Mosquito Control to spray all school sites overnight this Thursday evening.  It will be safe to access these spaces the following morning.  We are also working with both towns to coordinate efforts so that recreational fields in both communities will be sprayed the same evening.  

For questions or concerns about plans to spray school facilities for mosquitos, please contact:


I have also been in contact with our athletic director, Steve Martin and the Principals at RJ Grey and ABRHS.  If either of our towns is elevated to a “high” risk level, we will move start times for athletics and outdoor activities to end before dusk.

As you take advantage of the beautiful weather, keep in mind that students are outside for recess, physical education, and science/nature walks.  It is always a good idea to apply bug spray before they leave the house.  


Helpful information:


Eastern Equine Encephalitis Prevention (EEE) The most effective way to protect you and your family is to prevent mosquito bites. It takes only one bite from an infected mosquito to get EEE. Protections that you and your family can take are: 

  • know that peak biting hours are from dusk to dawn 
  • when outdoors, wear long sleeve shirts and pants 

  • acccording to the website noted below, use insect repellent with DEET (N, N-diethylm-toluamide), permethrin, picaridin (KBR 3023), IR3535 (3-[N-butyl-N-acetyl]-aminopropionic acid) or oil of lemon eucalyptus [p-Menthane 3, 8-diol (PMD)] according to the instructions given on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age. 

  • repair holes in screens or doors 

  • remove standing water from your home 

For guidance on how to protect your family from mosquito-borne illnesses and to mosquito-proof your homes, as well as the most up-to-date information about EEE, please visit these websites here:  


We will continue to monitor the situation on a daily basis and take appropriate steps to keep our students safe.
