A pest control professional can remove rats in as little as one day to a few days depending on the size of the infestation.
Rats and rodents in general are very sensitive to sound, since it's one of their main tools for survival. Any new or unexpected noise will frighten them and send them scurrying. However, once rodents get used to a sound, they will no longer fear it.
These experiments establish that rats can communicate fear and induce specific odor fear learning via pheromone information.
