Japanese knotweed detection dogs for fast, accurate surveys

Early, non-invasive knotweed detection for property and land

Japanese knotweed can spread extensively beneath the surface long before any visible signs appear, creating serious risks for property transactions, development projects and land management.

Our detection dogs offer a fast, non-invasive and highly accurate way to identify knotweed at its earliest stages, including underground, dormant, or concealed growth that traditional surveys often miss. By detecting infestations early and reliably throughout the year, we help homeowners, developers and surveyors make informed decisions, reduce costly delays and manage invasive species risk with confidence.

Why detection dogs over traditional surveys

How it works

Site assessment

We review your site and define the survey scope based on your needs.

Detection sweep

Trained dogs carry out a controlled search across the area.

Marking & identification

Any detections are clearly marked for accuracy and mapping.

Report

You receive a clear report with findings and next steps.

CDI

Smarter detection. Earlier insight. Better decisions.

Across Ireland, hidden risks undermine projects, budgets and long-term asset performance.
Corrosion and Japanese knotweed rarely reveal themselves early. They grow exponentially until damage is costly, hazardous, disruptive and increasingly difficult to control. Our specialist detection dogs identify risks at the earliest possible stage, giving you clarity long before traditional methods are able to confirm a problem.

Frequently asked questions

Can detection dogs find Japanese knotweed underground?

Yes. Detection dogs are trained to identify the scent of Japanese knotweed, allowing them to locate underground, dormant or concealed growth that may not be visible during a traditional survey.

When handled by trained professionals, detection dogs offer a highly accurate method of early identification. They are particularly effective in locating hidden growth that visual inspections may miss, helping reduce uncertainty during site assessments.

Detection dogs complement and often outperform traditional surveys when it comes to early-stage identification. While visual surveys rely on visible growth, detection dogs can identify knotweed before it emerges, allowing for earlier and more informed decisions.

Yes. Unlike visual inspections, detection dogs are not limited by season or vegetation cover. They can operate effectively throughout the year, including when knotweed is dormant.

The duration depends on the size and complexity of the site. However, detection dogs can cover large areas much faster than manual inspections, making the process efficient even for extensive sites.

No. Detection surveys are completely non-invasive. The process does not involve digging or disturbing the ground, making it ideal for sensitive or active sites.

If knotweed is identified, the locations are clearly marked and included in your report. You will also receive recommendations for next steps, which may include further investigation, monitoring or remediation planning.
