Residential knotweed removal methods

Below are the three core residential solutions we offer, designed to accommodate different timescales, budgets and levels of disruption.

DART excavation next to house

DART™ (Dual Action Residential Treatment)

DART™  combines targeted crown and rhizome removal with a structured herbicide programme. It offers:

  • excellent effectiveness
  • lower cost than full excavation
  • minimal disruption
  • a balanced option for typical domestic gardens

DART™ is ideal where immediate construction is not planned but faster results are desired than herbicide alone.

Resi dig out of Japanese knotweed

Resi-Dig-Out™

Resi-Dig-Out™  is the fastest and most reliable residential removal method. Adapted from our patented Xtract™ technology, it removes all viable rhizome within days.

Choose Resi-Dig-Out™ when:

  • extensions or landscaping are planned
  • certainty is required
  • previous treatments have failed
  • the problem needs resolving quickly

It is significantly cheaper than dig and dump yet far more reliable than herbicide or DIY approaches.

It is:

  • cost-effective
  • minimally disruptive
  • widely suitable for boundary and garden areas

If construction or excavation is planned in the future, Resi-Dig-Out™ is generally the recommended option instead.

A JKMP includes:
