North Ayrshire residents have been warned that now is the time to take action against the destructive plant Japanese Knotweed.
The plant, known for its fast and aggressive growth, is in its peak flowering season from late summer through August and early September.
Growing up to three metres tall with roots reaching down 20 metres, the plant is known for wreaking havoc on homeowners, destroying pipework, drains and even weakening building foundations.
Arran has been identified as North Ayrshire's hotspot for Japanese Knotweed.
According to invasive plant specialist Environet UK, 42 of the plants have been confirmed within 4km of Brodick alone, as well as 54 within 4km of Lamlash.
On the mainland, Irvine appears to be worst hit by the plant with 11 cases of Japanese Knotweed identified within 4km of the town.
The 2024 records show Kilwinning had an estimated five cases, the Three Towns had five cases, West Kilbride had six, Kilbirnie four, Dalry three, seven in Millport and three in Largs.
Some parts of Glasgow have recorded 138 sightings of the plant within 4km. While in London, some parts have recorded 265 sightings of knotweed.
While it hibernates over Winter, from March and April it returns and can destroy pipework, drains and can even weaken building foundations.

According to experts Japanese Knotweed Specialists, now is the time to act.
A spokesperson said: "Japanese Knotweed is most visible and active during the flowering season. If not controlled, it can quickly take over gardens and cause long-term damage due to its aggressive nature and strong desire to reproduce."
They said three critical indicators of Japanese Knotweed to look out for in the summer months are:
White to cream-coloured flowers
The flowers grow in clusters, known as panicles, which can be 6 to 15 cm long and feathery in appearance.
Heart-shaped leaves
The leaves are broad and heart-shaped, with a pointed tip. They range from 7 to 14 cm long and often grow in an alternate pattern along the stem.
Hollow, bamboo-like stems
The plant's hollow stems, similar to bamboo's, can be green, red, or purple. It has a zigzag growth pattern and can reach 3 to 4 metres (10 to 13 feet). It can form dense thickets that are difficult to control and penetrate.
