Residents in the West End are being leafleted about the risks posed by rogue traders and cold-calling conmen.
Cases of bogus workmen targeting the elderly in particular are actually on the fall.
But when incidents happen, they can leave victims devastated - and thousands of pounds out of pocket.
One 87-year-old man was recently robbed of more than £4,000 of life savings when he was tricked by a bogus workman.
That incident in Cloberhill Road in the High Knightswood area in early May is still be investigated.
Police will spend Friday (May 26) leafleting households and businesses in the area to help people keep safe.
PC John Murray based in Drumchapel said it was important to raise awareness now.
"This is the time of the year when conmen are out and about looking for targets.
"We can give simple advice to people that can keep them safe. It's about raising awareness and educating the public."
WEATHER IMPROVES
Business and residential premises have been visited throughout the West End, with posters, leaflets and "No Cold Callers" stickers handed out.
Operation Monarda has been ongoing throughout the city since earlier this month.
Officers have been supported by colleagues from Trading Standards, Scottish Fire Service, Care and Repair and the Good Morning Service.
As the weather improves and the days are longer, there is a greater chance of someone calling unannounced at your door.
Chief Inspector David Pettigrew:"Although anyone can be a target, older people are who these criminals tend to target most because of a perceived vulnerability and it can have a hugely detrimental effect on the life of victims.
"Yes, sometimes people can be embarrassed that they have been duped, but please don’t be, it’s not your fault. Always call police."
Police are reminding people to always ask for identification if someone calls unannounced - and call the company to verify the visit or simply refuse entry.
Chief Inspector David Pettigrew, Safer Communities, said: “In the last six months, the number of bogus caller crimes in the Greater Glasgow area has fallen by 64%.
"There have been 27 bogus caller crimes reported to police compared to 76 recorded for the same period last year."
He added: "Although anyone can be a target, older people are who these criminals tend to target most because of a perceived vulnerability and it can have a hugely detrimental effect on the life of victims.
"Yes, sometimes people can be embarrassed that they have been duped, but please don’t be, it’s not your fault. Always call police."
