Police tackling bogus callers and doorstep crime have stopped more than 50 contractors already this week.
Operation Monarda, running in Aberdeen, Aberdeenshire and Moray, is aimed at highlighting the threat posed by opportunist crooks.
Working with trading standards teams, officers are targeting offenders and offering the public advice on what to be on the alert for.
The teams are visiting banks, leisure centres, libraries, GPs and dentists to engage with the community, as well as elderly or vulnerable residents.
Yesterday, they revealed they had stopped and assessed 30 vehicles and 54 individuals.
Trading standards officers have also warned a number of individuals about their trade practices.
Chief Inspector Kevin Wallace said that if anyone is concerned about how doorstep crime could affect them or their loved ones, they should contact the police immediately.
He said: “Victims of bogus callers and doorstep crime are often unaware the crime has been committed.
“When they do realise, they often feel embarrassed by what has happened, and feel they are unable to go to the police.
“It goes without saying that in addition to the devastation caused, the crime can have a massive impact on their financial circumstances too.
“I want to reassure the public and send out a strong message to those involved in these activities that it will not be tolerated, and police will continue to work tirelessly with our partners to put an end to these incidents.”
Operation Monarda will continue until Monday.
