Step 3 – Choose the right treatment option and implement the Knotweed Management Plan

Now that we’ve completed the survey it’s time to decide which solution best fits the need of the problem.   But let’s not forget that no two properties are the same, and neither are any two infestations.

And for that there are three main remediation strategies for residential infestations of Japanese Knotweed to consider:

  • Herbicidal Control – We apply targeted herbicides to Japanese Knotweed over multiple growing seasons to ensure we effectively deal with the problem.   Be this though stem injection or foliar application our technicians work hard to ensure Japanese Knotweed can’t redevelop 
  • Full Removal (Excavation) – When time is a limiting factor, we can excavate all soils from a property containing Japanese Knotweed to a registered landfill facility. This ensures all traces of the plant are removed in one visit and we follow this up with monitoring visits as part of our PCA Accreditation
  • Capping (Partial Excavation) – Where access is an issue or knotweed is growing close to a built structure, we can partially excavate Japanese Knotweed and install a specialist root barrier to the excavation pit that will prevent knotweed rhizomes from redeveloping within the excavation area

All our herbicidal control and excavation management plans come complete with our 10-year warranty that protects a property against any unlikely regrowth with the option to include a 10-year Insurance Backed Guarantee (IBG).

So once you’ve decided to instruct Inspectas to deal with the Japanese Knotweed you can be assured of our commitment to resolve the problem and for that we’ll:

  • Contact you within 24 hours of written instruction to carry out the works to schedule the first visit
  • Schedule the eradication programme around your needs
  • Contact you 7 days prior to any visit to advise on our attendance and then contact you on the day to advise our time of arrival
  • Conduct annual audits on your property to ensure best practices are always being adhered to.
  • Provide annual updates on the process of eradication
  • Be discreet when carrying out the process of eradication – none of our company vehicles advertise that we are dealing with Japanese Knotweed

And don’t just take our word for it:
