Japanese Knotweed strand showing charictaristig zig-zag growth


Invasive weeds like Japanese Knotweed grow rapidly and can damage buildings and pavements by growing through cracks and weaknesses. Even a small part of the root or stalk can regrow into a new plant, so soils from Japanese Knotweed infestations must be treated as controlled waste. Other weeds, like Giant Hogweed which causes severe skin blisters, can pose a health risk to site workers or members of the public.


ERS understand the issues caused by invasive weeds. Our highly experienced team of Invasive Weeds specialists work with home owners, property developers, local authorities and other stakeholders across Scotland to identify, assess, manage and remediate land that’s infested with invasive weeds. No job is too big or too small, and we are happy to offer you advice or do an assessment if you suspect growth on your property.


Our treatment programmes start with a thorough site survey to assess the extent of the infestation.  This is followed by a complete management plan, which takes into consideration the client’s timescale and budget plus any regulatory requirements, and outlines the most appropriate treatment methods. As Property Care Association (PCA) members, we can offer a 10 year insurance-backed guarantee for all our treatments, so you can relax in the knowledge that the plants have been successfully treated.


The most common treatment techniques for invasive weeds remediation are in-situ herbicide treatment, excavation and stock-piling for on-site treatment/ off-site disposal and combined digging and herbicide treatment. We’ve also had good success with weed barriers which prevent the weeds returning/ spreading onto neighbouring land.
