Squirrels causing holiday light display headaches in Boston

Christmas lights in the Boston Common are being damaged by voracious squirrels.

The Boston Globe reports the furry rodents have chewed through electrical wires for the colorful, festive lights.

City parks officials say they've received reports about holiday light display outages on the city's online reporting app.

One recent visitor noted nearly half the lights on the Common's main 47-foot white spruce Christmas tree were out, an issue the city says has since been addressed.

The lights are hung on about 60 trees, the visitor's center and other buildings in the historic downtown park.

The contractor hired to string and maintain the lights has turned to using an organic product to deter the animals. A parks department spokesman says the squirrels appear to have a fondness for copper.
