Cold callers are no longer welcome across much of the Falkirk area

The no-go areas, covering an area of about 5,000 households, have been set up across the Falkirk district.

They were launched by the council and Central Scotland Police amid concerns about bogus callers defrauding residents or robbing their homes.

The move also aims to tackle so-called "high pressure" sales reps using hard-sell tactics on homeowners.

Almost 100 Falkirk Neighbourhood Watch areas have also backed the scheme, which uses lamppost signs and window stickers telling callers that they are not welcome.

Falkirk Council community safety convener Diane Williamson said: "One of the main targets for these practices is the elderly, especially ones who are housebound or live on their own.

The initiative was launched after an increase in complaints to trading standards officers about cold callers, and Central Scotland Police has offered residents in other areas help to set up similar schemes.

Falkirk area commander Supt Gordon Samson, said: "Bogus callers of all description target those who are considered to be among the most vulnerable members of our community.
