Japanese knotweed is not a problem worldwide, in fact in countries where it is native it causes very few problems at all. This is because natural control methods, such as competing flora and fauna restrict its aggressive growth. Some of these natural methods are currently being trialled in the UK to assist the control of Japanese knotweed and help reduce the cost of treatment in the future.

One prominent example of natural control of Japanese knotweed is an on-going trial in Wales which has seen insects imported from Japan that eat Japanese knotweed released into the wild. Although these insects will never completely eradicate Japanese knotweed (as without it they can't survive) it is hoped that they can reduce the amount of Japanese knotweed and stop it from spreading further.
