Rats don't like the smell of peppermint, so placing peppermint oil on cotton wool balls in corners of your home will help to keep them away. Replace this every few days to ensure they keep their distance.
This makes peppermint oil, chili powder, citronella, and eucalyptus the most common natural rodent repellents. Chemical smells, such as ammonia, bleach, and mothballs also work as mice deterrents.
Rats are afraid of human activity, mostly because humans are so much larger than they are. Rats also fear predators such as hawks, eagles, and other birds of prey. Other animals that rats are afraid of include your cat as well as rat terriers and other dogs that hunt rodents.
The smell of ammonia is very pungent that it instantly kills rats.
Famously, birds of prey feed on mice and rats. Raptors, including hawks, owls, eagles and falcons, are common predators. Red tail hawks, found across most of North America, and American kestrels, the smallest falcon in North America, will hunt rats by day.
Structural Damage
Rats can gnaw through the structural wood framing of your house, including floor joists, headers, studs, and roof trusses. They'll chew through sheetrock, soft concrete, and even your drywall. Basically, rats can and will chomp through your house to get where they want.
It turns out that baking soda catalyzes some form of reaction inside the rat's stomach. Baking soda combines with the stomach acids to produce carbon dioxide gas which rats are unable to tolerate. In turn, it builds up within their system and eventually causes internal blockage and rupture.
The smell of white vinegar is also effective for repelling other pests such as rats, roaches, spiders, and ants.
Odors and smells that come from pet waste, pet food, garbage containers, barbecue grills, birdfeeders, and even from unharvested fruit and nuts from plants can attract rats and mice. Good sanitation habits can effectively improve the prevention of attracting rodents in your yard.

Both rats and mice are good climbers and can climb vertical walls and "shimmy" up between walls and drain pipes. Rats are also excellent swimmers and have been known to enter premises through the water traps of the toilet bowl when infestations occur in the main sewerage system.
Healthy rats typically avoid people and prefer to be active when buildings are quiet. However, when cornered, they will lunge and bite to defend themselves. The saliva of some species of rats carries hazardous diseases, such as leptospirosis and Hantavirus. In rare cases, rat bite victims may contract rat-bite fever.
In these environments, large birds of prey — including hawks, falcons and owls — feed regularly on rodents. Owls are particularly formidable predators, as their nocturnal behavior ensures that they are most active when rats go out in search of food. Various snake species also prey upon rats.
Chocolate is not poisonous to rats, as they are able to digest the chemical theobromine, which can be harmful to other animals. However, only use chocolate as an occasional treats, as although they do enjoy it, it can lead to weight gain and conditions such as diabetes.
Their preferred produce is avocado and citrus fruit. These rats are known to eat fruit right off the tree. With some fruits, such as lemons, roof rats eat the rind but leave the flesh.
