Herbicidal Japanese Knotweed Treatment Services

Herbicidal treatment offers a reliable, cost-effective way to control invasive weeds. At Eco Control Solutions, we build tailored treatment plans around your site, using PCA-compliant methods and licensed herbicides.

Why choose us for herbicidal weed control?

Eco Control Solutions has delivered specialist herbicidal treatment programmes since 2007. Our approach is grounded in a detailed understanding of plant behaviour and developed through extensive experience across a wide range of sites.

Every project is assessed individually. We build tailored treatment plans that take into account timescales, site conditions, ecological factors, and proximity to neighbouring land.

How does it work?

Site visit or

We assess the site using images or by arranging a visit, confirming the presence and extent of the knotweed.

You’ll receive a clear plan outlining the best removal method, herbicidal, excavation, burial or translocation, based on your needs.

Removal carried out
with precision

We deliver the chosen treatment using licensed methods, whether that’s excavation, spraying, or burial, while keeping the site safe, compliant and contained throughout.

Ongoing protection and
full documentation

Backed by a 10-year warranty and Optional Insurance Guarantee.

All documentation is issued for legal, lender or planning use, giving you long term peace of mind.

Site visit or

photo ID

We’ll confirm the species and assess the site using photos or an in-person survey. This helps us understand how the plant is growing and how best to treat it.

Treatment recommendation

You’ll receive a tailored herbicidal treatment plan based on site layout, timing, and species. We factor in surrounding land, access, and long-term goals.

Licensed treatment delivered on site

Our trained team applies herbicide using approved methods at the right time of year. The process is targeted, compliant, and designed to minimise disruption.

Monitoring and documentation

We revisit to monitor results and adjust the plan if needed. Full documentation is provided to support legal, planning or lending requirements, with optional warranty cover.

Residential property

Japanese Knotweed Excavation and Removal in Residential Property

Our client was the owner of a residential property with very limited access to the rear of the house, which comprised of a decked terrace overlooking a long, narrow garden, which sat several feet lower than the house. There were two infestations of Japanese Knotweed present within the garden. The first was growing underneath and around a garden shed, the second was growing in a rockery that had previously been a pond. The client opted for a full excavation and removal, rather than a treatment solution, as they had plans to redesign the garden.

Frequently asked questions

Is herbicidal treatment suitable for all invasive species?

It depends on the species and the site. Japanese knotweed and horsetail often respond well to herbicide, but where fast results are needed, or infestations are extensive, excavation may be the more effective option.

Is the herbicide safe for pets, wildlife or watercourses?

We only use licensed herbicides and follow strict regulatory guidelines. Where watercourses are present, we apply for the appropriate permits to ensure safe and legal treatment.

Can you provide documents for lenders or planners?

Yes,  once the work’s complete, we’ll provide full PCA-compliant documentation to support planning or lending requirements. We can also offer optional Insurance-Backed Guarantees for added long-term assurance.
