The only effective way to remove yellow soldier is through spot-spraying of herbicides. Once again, however, the ability to quickly germinate from seed means that multiple courses of spraying must be done in order to completely eliminate yellow soldier, and allow native species the chance to reclaim the soil. The herbicide developed to kill only yellow soldier is expensive and therefore can usually only be done through government funding. This prevents most environment and bush care groups from eliminating the species, and thus allowing it the chance to spread further.
