Perth and Kinross residents have claimed the council is failing to deal with the annual spread of a toxic plant which causes blisters and burns on human skin.
Homeowners say poisonous Giant Hogweed plants are among a wave of invasive species growing at an alarming rate throughout the region.
The plant can cause significant blistering which can take months to heal. Just a brush is enough to start a potential reaction and eye contact with the sap can also cause blindness.
Elspeth Buchanan of Inchyra, said: “Giant Hogweed, Japanese Knotweed and Himalayan Balsam are rampant on the banks and areas adjacent to the River Tay, beside the Friarton Bridge and next to the Perth/Dundee railway line between Perth and Inchyra where I live.
“I have also noticed other areas of the same species on other parts of the Tay from Loch Tay to the estuary.
“However, I am sad to report yet again that still nothing seems to be being done to eradicate these species. Now is the time to deal with this not when the enormous flowers have set seed.”
Giant hogweed can grow to between two and five metres in height. Though the plant dies back in winter, it grows again in the spring and excels at propagating itself, with each flower capable of producing 20,000 seeds.
Further Giant Hogweed, more than six feet in height, has been spotted between Perth’s Tesco petrol station and Crieff Road, close to the crash barrier.
One concerned resident said: “As it is almost the school holidays some child might not be able to resist smashing it up and will not know of the dangers of the sap.”
The Royal Horticultural Society advises that when controlling the plant, gloves should be used, arms and legs covered and a face mask worn.
Perth councillor Willie Wilson said ongoing work was being carried out by both the council and private businesses to eradicate the region of invasive species.
He said: “Muir Homes have carried out two treatments to Hogweed at Low Road. From a recent visit by myself and a colleague from our local greenspace group this seems to have been effective.
“Perth and Kinross Council have also carried out treatments at an adjacent site near Orchard Place in Craigie. Craigie Hill Golf Club has also done sterling work on land adjacent to the golf course on some difficult terrain.
“Anyone tackling a Hogweed infestation should take great care for their own health and safety.”
A Perth and Kinross Council spokesperson said: “As part of the council responsibilities for greenspace maintenance, we carry out the treatment of weeds in areas of council responsibility, this includes Giant Hogweed.”
