Case Study on

Vacant Land – Stoke-on-Trent [Commercial]


This Vacant land has belonged to the owners for a number of years. It was originally a Pig Farm & later used by several different commercial businesses. Over recent years it has been derelict and has become a regular spot for fly tipping including rubble, old car and truck tyres and lots of overgrown flora.

The owners also have neighbouring properties which are owned and let out to various businesses. The infestation of Japanese Knotweed is substantial and has grown in between & around abandoned tyres making it much more difficult to treat.

The area has previously been treated by the chemical Glyphosate for several years the knotweed has continued to grow and expand. The owners realised first hand that the chemical treatment was not helping to reduce the infestation, and after doing research they discovered our website offering the Thermo-Electric treatment with the promise of eradication and noted the success of this treatment used in Europe for agriculture and indeed Japanese Knotweed.

Follow up

The site has been attended several times in order to cover the vast infestation and thermo-electric treatment applied to all the Japanese Knotweed. When treating this area, it is clear that chemical has been used, as when thermo-electric is applied to the Japanese Knotweed it releases a very strong smell unlike untreated Japanese Knotweed.

In an effort to reclaim the site for some light storage use down the line, we have dropped trees to the ground and maintain the area to keep some clear control while we keep a thermo-electric attack on the Japanese Knotweed.


Japanese Knotweed as expected has returned albeit there is clear evidence the Knotweed is not as virulent as it was in 2023 when we started thermo-electric eradication. The Knotweed stems on this site when we first attended were the largest we have seen to date, with stem width appearing to be 6 inches.
The site is attended at least monthly and thermo-electric applied.
