Lexington sits in Middlesex County with a humid continental climate that brings cold winters and warm summers, driving clear pest patterns. Spring termite swarms appear as soils warm, while fall sees rodents pushing into older homes near Battle Green and Lexington Depot as temperatures drop. Summer brings mosquito and wasp pressure around wooded edges and irrigated yards.
Everything that follows applies right here in Lexington (02420): the offerings, the process, and the pricing approach we use statewide.
Boston attics in older Beacon Hill and North End buildings often hold years of rodent nesting material mixed with blown-in cellulose that has absorbed moisture from our humid continental climate. After removing the animals we pull all contaminated insulation, vacuum droppings with HEPA equipment, and treat surfaces with EPA-registered disinfectants before installing new R-38 fiberglass batts or closed-cell spray foam to meet current energy codes.
Edge cases we see regularly include bat colonies that have stained rafters in South End brownstones and squirrel chew damage around Harvard Bridge-area eaves that allows water intrusion. We never seal an attic until every entry point larger than a quarter inch is screened with ¼-inch galvanized mesh; skipping this step guarantees repeat calls within one season.
