Unless it is actually in the way - for instance overhanging paths, i am not sure why there is a need to get rid of HB at all. Introduced to Britain as a garden plant in 1839, it is our fastest growing annual with beautiful flowers and explosive seed pods loved by children. There is a good display at Marple station where everything else has finished flowering. The Environment Agency hate it, and there is a fairly hysterical charge-sheet, but I've looked at the scientific papers behind them, and there isn't any real evidence that HB affects native species, bees, erosion or anything else. It tends to colonise disturbed and high-nutrient habitats that are poor for other plants and animals anyway.
If you click this link I've put a bit more information: http://www.blackfryers.co.uk/news-and-blog. Enjoy your HB!
