Before the days of rat poison people either had to live with rats in their home, which was normal for the time and nothing to worry about, they did not know the dangers as well in the days before industry changed the world. People would often not bother getting rid of the rats but those who found them offensive would need to find an approach on their own. Either to go to the apothecary for a poison to use on the rats or to try to chase them away with repellents.

If you have a severe rat issue you can try dealing with it using these ancient methods that often are quite effective, if only on small infestations. Rats and other rodents are repelled by the smell of very spicy spices. Hot chilly pepper and Cayan are the most effective and can be sprinkled around the home to bother the rats. To make an even more potent treatment the spices can be mixed with oil to make a liquid spray with will stick to surfaces and cause havoc for the rats as they try to travel. Getting this in their mouth or eyes is highly dangerous as rodents cannot cough, gag or cry and if something dangerous gets in their mouth they will choke on it and if a chemical gets in their eyes they will go blind. The likely result is the rats will start leaving your home as they do not like the smell of the spices but they may also simply travel deeper into the house to avoid the oil. Which house mice hunt for food in the house, rats leave the house to hunt for food most of the time. You may be able to catch them with a bated trap on the inside but knowing what bait to choose is half the battle. Cheese, for instance, is something a rat can eat but not something that they desire. Rotting shellfish shells on the other hand will bring every rat in the house running to the feast.
If you have tried the spicy method and it is not working the best thing to do is to stop doing it and to call a professional. A trained rodent technician can inspect your home for activity, burrows, populations of rats and possible entryways they are using to get into your home. Not just that but he can also deal with those entryways and properly bait active areas with potent commercial-grade bait and poison. This is the fastest and most effective way to deal with rats.
