ERS' highly experienced in-house team of invasive weeds specialists are experienced at treating not just Japanese Knotweed, Giant Hogweed and Himalayan Balsam, but a range of other invasive non-native species causing issues for homeowners, property managers and land owners across urban and rural Scotland. As well as "the big three", we are increasingly getting enquiries for gardens affected by Bamboo, woodland and parks affected by Rhododendron and brownfield land affected by Buddleja.


We work with home owners and property managers, housebuilders and developers, landowners and estate managers, national parks and local authorities, and many more 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 invasive weeds survey if you suspect invasive non-native species (INNS) are growing on your property.


Our invasive weeds 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. In addition to our treatments, we can also offer revegetation with native trees and shrubs to prevent bare patches of land post-treatment which look unsightly or could be vulnerable to erosion.


Our expertise covers a wide range of weeds, including: 

We understand invasive weeds are a complex subject so we have put together a free downloadable Invasive Weeds Guide. There are many more invasive plants in addition to those pictured above that our team are able to treat, so please get in touch if there is a plant of concern on your site/land that isn't listed. More information on invasive alien species (IAS) threatening Scotland can be found on the website.


Our invasive weeds specialists also have the skills in-house to incorporate re-vegetation and landscaping reinstatement into our invasive weeds management plans without having to outsource. In a domestic or industrial setting, this can save homeowners and property managers the hassle and cost of having to arrange re-landscaping themselves. However in rural and ecologically sensitive environments, re-vegetation can help meet other objectives, such as wildlife habitat development and maintenance of ecological function, and is an important but often overlooked area of sustainable invasive weeds management.


If you have concerns about invasive weeds on your site/land, please contact us today to speak to one of our experts.
