The Town of Littleton belongs to the Central Mass Mosquito Control Project, a program comprising mosquito surveillance, larval mosquito control, and public education. In Littleton, larvicide applications to small wetlands occur in spring and summer, helicopter spraying to larger wetlands occur in April, mosquito trapping and surveillance occurs in June, and treatments to catch basins are applied mid-summer. There are many areas that are treated. If you want to know if the area you live in is treated, please call (508) 393-3055 to speak with a representative of the program.
