Cornwall recorded the highest number of invasive weed complaints in Britain, according to analysis from Environment Controls.
Councils received 7,899 complaints about Japanese knotweed, giant hogweed, bamboo and Himalayan balsam over the past five years.
Cornwall Council received 633 complaints since 2021, followed by Surrey County Council with 546 and North Lanarkshire Council with 517.
Cornwall also recorded the most Japanese knotweed complaints, with 552.
Argyll and Bute recorded 315, followed by North Lanarkshire with 295.
Environment Controls advised homeowners not to cut or dig up unidentified invasive plants, as this could cause them to spread.
It said homeowners should photograph unfamiliar plants, keep children and pets away from suspected giant hogweed and check plants growing near property boundaries.
Homeowners were also advised to speak to neighbours if a plant was spreading from adjoining land.
Jennifer Holmes from Environment Controls, said: “Early identification is important because different plants require different treatment methods.
“Trying to remove an invasive weed without understanding what it is can make the problem worse and increase the risk of spreading it.”
