What Smell Are Rats Afraid of?

Scientists have found that rats are frightened of the smell of predators, such as cats. The smell elicits a high level of fear in rats, leading them to avoid the predators altogether. Researchers have isolated this scent from uriney proteins secreted by cats, snakes, and other predators.

Another common smell that rats avoid is peppermint. While it is not a highly effective repellent, rats will avoid areas that smell like peppermint. Peppermint can be applied with cotton balls or plants around the perimeter of the home. This solution will repel rats and keep them away for a while.

Another effective repellent for rats is cat fur. You can purchase cat fur from pet stores or ask your friends and family for some. Pepper flakes can also be used to deter rats. Rats do not like the smell of pepper, so sprinkle some on the affected area every couple of days. These methods work well for controlling rat infestations, but you must take special care not to harm your pets and other pets.

Another repellent for rats is citronella oil. Citronella oil has a strong, clean smell. Since rats are scent-driven, it makes them feel uncomfortable and unsafe.
