What is the first stage of rat infestation?

The first stage of rat infestation is often indicated by the visual signs of the presence of rats, typically described by seeing rats themselves alongside their droppings. This stage marks the initial awareness that there is an infestation occurring. By recognizing both the rats and their droppings, it signifies that they are not only present but also active in the environment.

This awareness is critical for implementing control measures promptly before the infestation escalates. It is important to note that while hearing noises, seeing droppings, or finding nests are signs of infestation, they may not be as definitive as spotting the actual rats. The combination of sighting rats and their droppings allows for immediate recognition and action, positioning it as the first observable stage of an infestation.
