Will there be any disruption to the house/garden whilst the works are carried out?
Yes, the amount and duration of disruption depends on what method is adopted. We endeavor to keep the disruption to the minimum but inevitably some loss of enjoyment that the property and garden provides will be experienced.
Are there any precautions we need to be aware of where herbicides are applied?
Yes, we request the following:
- Do not allow the above ground knotweed vegetation to be trampled on, cut down or damaged. Damage to the above ground part of the plant makes the treatment using herbicide less effective. In certain circumstances it can also lead to further spread.
- If you cannot control access then you should consider putting up fencing and warning signs to prohibit unauthorized access into the affected area.
- Remain vigilant for signs of new outbreaks in new areas within the property’s boundary and on adjoining land. If you identify knotweed shoots in new areas report these to us. This will allow the further assessment of the extent to be determined and treatment to take place.
- During application of herbicide by our operatives please keep persons and pets out of the area. The herbicides used are not harmful to mammals if used correctly, however unnecessary exposure should be avoided.
- When the treatment programme is complete please abide by the requirements within the Post Treatment Management Plan that is issued for all Environet projects benefitting from a guarantee. This will ensure that any residual risks after treatment completion are adequately managed.
