All noxious weeds, at any and all stages, their carriers, and any and all premises, plants, and things infested or exposed to infestation therewith may be declared to be a public nuisance by the local governing body having jurisdiction over the lands upon which said noxious weeds are situated. Once declared, such nuisances are subject to all laws and remedies relating to the prevention and abatement of nuisances. The local governing body, in a summary manner or otherwise, may take such action, including removal and destruction, with reference to such nuisance as in its discretion appears necessary. The remedies of this section shall be in addition to all other remedies provided by law.
