What does the acronym FIFO stand for?

The acronym FIFO stands for "First In First Out." This principle essentially means that the items or products that are received first are the ones that should be used or sold first. This concept is particularly important in inventory management and pest control settings where materials used can have expiration dates, effectiveness, or quality concerns. In scenarios such as pest control, using the oldest materials first helps ensure that you're maintaining the efficacy of your treatments and adhering to safety protocols by using products before they expire. This approach can also aid in preventing the financial loss associated with unsold or unused inventory, as it promotes a streamlined process for managing materials.
