Flying squirrels enter Boston attics through gaps as small as a quarter, often along rooflines of brick row houses in Beacon Hill and the North End where original flashing has shifted. We locate these points during daytime inspections, then install metal flashing and foam backer rod that withstand freeze-thaw cycles from the Atlantic-moderated climate.
In multi-unit buildings in the South End and Charlestown, squirrels travel between units through shared chaseways; one-way doors must be placed on the exterior only after confirming no pups remain inside. We remove soiled insulation and droppings to eliminate scent trails that attract new animals, then seal with copper mesh rated for historic masonry.
Massachusetts wildlife rules require live trapping and release; we use box traps checked every four hours to stay compliant and avoid stress on the animals. Properties near Boston Common or the Public Garden often need chimney and vent guards because squirrels use these as regular travel routes between trees and roofs.
After exclusion we install soffit vents with 1/4-inch hardware cloth so airflow continues while blocking re-entry, a step that prevents moisture buildup in the humid summers typical of coastal Suffolk County.

✓Attic Entry Point Sealing
Locate and permanently close gaps around rooflines, eaves and flashing on Beacon Hill and Back Bay row houses using metal and mesh that matches existing materials.
