Why is it important to identify the source of an odor before treatment?

Identifying the source of an odor before treatment is crucial because it helps to prevent the odor from returning. Odors are often a symptom of underlying issues, such as contamination or decay, which must be addressed directly. If the source isn't found and eliminated, any treatment applied can only mask the odor temporarily rather than resolve the issue permanently. For example, if a lingering odor is caused by mold or sewage, no amount of air freshener or surface cleaning will suffice; the mold or sewage must be dealt with to fully eliminate the odor. Therefore, thorough identification of the source leads to a comprehensive approach in dealing with the problem, ensuring that the odor does not resurface after treatment.
