Police are warning South Burlington residents about door-to-door work crews.
They say the crews offer to do yard work like raking leaves. But police believe they are actually casing homes.
"The real purpose is to find out if you are in fact home. If you are not, they are going to find a way into your house and take what belongs to you," explained Det. Ron Bliss, South Burlington Police Department.
Police want you to call if you see this activity in your neighborhood.
They also remind everyone that most legitimate businesses do not advertise door to door.
