Residents concerned about mosquitoes can call the Central Massachusetts Mosquito Control Project office to schedule an inspection and possible spraying of their property on Tuesdays and Wednesdays through the end of July. These dates are tentative, however, and this program is suspended when cool nighttime temperature becomes predominant in this area. Representatives from the state office will visit properties and determine whether to apply insecticide. The inspector will also offer suggestions on how to prevent mosquito infestations, including removing anything that could collect water. To schedule an appointment, call the Central Massachusetts Mosquito Control Project office Monday through Friday from 7 a.m to 3:30 p.m. at 508-393-3055, or visit its website, www.cmmcp.org.
