Knotweed & Giant Hogweed Control in the Lower Mainland

Invasive plant control
2012 - Ongoing

DHC’s experience with knotweed and giant hogweed treatment includes treatment in a variety of land use types; parks and natural areas, roadsides and back alleys, maintained landscapes, railways, and residential and commercial properties. Our experience in parks and natural areas includes working in riparian zones. Our operational crews understand the sensitivity of riparian areas and adhere to pesticide application restrictions near water courses.

The majority of DHC’S operational work takes place on public land, often in parks where public interaction is an expected part of the job. We recognize that above and beyond ecological significance of the work, fostering a positive relationship with the public is of utmost importance and is critical to the ongoing success of a municipal invasive plant control program. Chemical treatment is a highly concerning topic to the general public. Our crews are always careful to ensure the physical safety of both the public and themselves. Our chemical treatment crews are trained to maintain a positive, calm and non-confrontational demeanor.
