Glow in the dark posters are being installed in play areas in Brockworth to encourage 'thoughtless' dog owners to pick up their mess.
Brockworth has joined the ranks of dozens of parishes across the country to use these signs as a way of urging dog owners to pick up their litter and humiliate those that don't.
The signs, which charge up during the day show illuminated human eyes with the words "Thoughtless dog owners – we're watching you!".
Brockworth Parish Council agreed to use the posters at a meeting last month as a way of dealing with the dog mess problems at their play areas.
Chairman Jim Hunt said: "We are trialling the posters for a month in the parish's problem areas.
"Unfortunately people take their dogs walking in the big playing fields and let them run around and don't bother trying to find and pick up their dog mess.
"Our local football teams have to go out before their games and clear up the dog mess that has been left before they can play every week.
"It's a real problem and we are hoping these posters will prove to be effective in dealing with it."
As part of the trial members of the council will be going to the playing fields and painting a line around any dog mess that has been left behind.
"We will use a different colour every day in order to see if the signs are working and the amount of mess being left reduces.
"Hopefully this will shame those few dog walkers into doing what the majority of people do and clean up their mess."
According to Keep Britain Tidy, the charity behind the signs, dog fouling increases during the winter, when the days shorten and more people walk their dogs in the dark.
Phil Barton, chief executive of Keep Britain Tidy, said: "The vast majority of dog owners are responsible people, who habitually pick up after their dog and dispose of the poo bags correctly, either in the nearest bin or by taking home to dispose of in their own household waste bin.
"But our most recent research tells us that people see dog fouling as, by far, the most unacceptable and dirtiest type of litter, and the biggest concern in environmental quality."
The posters, the first glow-in-the-dark signs to be used in a national advertising campaign, use cutting-edge materials to capture enough light during the day to show for around 10 hours each night.
They are waterproof and can be attached to lamp posts, fences or wherever local councils feel is appropriate.
Some concerns have been raised by members of the public avout the use of the signs claiming they are 'too scary'.
