Precautions to observe before, during & after a spray application

Generally, there is no need to relocate during mosquito control spraying. The pesticides have been evaluated for this use and found to pose minimal risks to human health and the environment when used according to label directions. Although mosquito control pesticides pose low risks, some people may prefer to avoid or further minimize exposure. Some common sense steps to help reduce possible exposure to pesticides and allow the technicians to perform a better applications include:

  • Listen and watch for announcements about spraying in the local media and remain indoors during the application to the immediate area.(please remain inside for 15-20 minutes, or longer at your discretion) Click here for our notification process:


  • People who suffer from chemical sensitivities or feel spraying may aggravate a preexisting health condition may consult their physician or local health department and take special measures to avoid exposure. (please notify CMMCP to be placed on the "No Spray" list - 508.393.3055 or e-mail) Click here for the exclusion process:


  • Close windows and turn off the outside air setting on window-unit air conditioners (if any) when spraying is taking place in the immediate area. (central air conditioners do not take air from the outside - you may open windows 15-20 minutes after the application, or longer at your discretion)


  • Do not let children play near or behind truck-mounted applicators when they are in use. (pets should be brought inside if possible or their cages covered to allow a wider application to be performed) If pets are outside no reason to worry, this pesticide is similar to ones used for flea and tick control but in much smaller amounts.
