Rats dislike annoying sounds, peppermint oil, toilet cakes and places where they cannot find food. People who are looking to remove rats from their home often look for the things that rats do not like in order to drive them out and keep them from returning.
Rats need to eat like any other animal and when they are in a home without any food, they tend to leave because they dislike staying in places where they cannot find food. Rats also do not like the sound that ultrasonic rat control repellant items make. These annoying sounds make rats want to run away from the home. However, some rats can get used to this sound and will stay despite disliking it. Another dislike of rats is the smell of toilet cakes and the smell of peppermint oil, which can both make a rat find a new place to live.
