How may the commissioner abate a nuisance?

The correct choice is focused on the active management of a nuisance, particularly in relation to pest control. The commissioner has the authority to abate a nuisance by taking concrete actions such as eradicating, controlling, or destroying the pest. This approach is aligned with public health and safety standards and demonstrates a proactive commitment to resolving issues that could negatively impact the community or the environment.

Effective abatement means taking measures that directly address and eliminate the root cause of the nuisance, rather than simply providing temporary solutions or fines which may not yield long-term results. By focusing on eradication or control, the commissioner can help mitigate risks and improve the overall quality of life for residents in the affected area.

The other choices do not provide effective solutions. Ignoring a nuisance would allow the problem to persist, potentially worsening the situation. Fining the owner may serve as a deterrent but does not resolve the immediate issue at hand. Issuing a warning could alert the owner but again does not take direct action to abate the nuisance. Therefore, actively eradicating, controlling, or destroying the pest is the most effective and appropriate method for the commissioner to fulfill their duties regarding nuisance abatement.
