What Does a Rat Sound Like? Rat Audio Thought you heard a rat? Listen to an audio recording (mp3 file) of rat noises and sounds. Rat Home-invading rats are typically brown to black in color. They have long tails and poor eyesight, but excellent hearing, smell, taste, and touch. The pests are skilled jumpers, climbers, and swimmers, which helps them sneak inside buildings. Infestations tend to gather in attics, basements, and the spaces between walls. Rat Noises Rats make a combination of squeaking, hissing, and chattering sounds. They can communicate different emotions depending on the frequency of the noise. Often, squeaks or hisses signify that a rat is afraid or in pain. The pests also chomp and grind their teeth. Finally, rats can be heard scratching, gnawing, and rustling inside homes. Risks & Dangers Not only do rats infest homes and cause costly damage, but they also threaten the health of residents. Rodent diseases are spread through bites, when individuals breathe in dust from rat droppings, or the ingestion of contaminated food or water. The diseases they're capable of spreading include leptospirosis, rat-bite fever, and salmonellosis. They can also cause destruction to wiring, walls, and insulation where they nest and feed.
