Litter louts are costing the public purse tens of thousands of pounds a year by dropping chewing gum on the streets of Perth.
Specialist equipment is needed to remove the unsightly and sticky mess from pavements and pedestrianised zones.
Despite campaigns and education work, gum is still being dropped in the city on a regular basis.
The blight is costing the council more than £20,000 a year to clean in Perth alone and has required further investment in the £3,000 gum-cleaning units.
That is just one part of an annual £2.5 million clean-up bill paid out by Perth and Kinross Council’s waste services team.
Teams have been out in force in recent weeks, using specialised equipment to lift the sticky mess.
They have been targeting hotspots and their efforts are being backed by a new public information campaign in conjunction with Zero Waste Scotland.
