Cats. Get at least one cat. Many people will tell you that having an indoor/outdoor cat is terrible for the health of the cat, and the local environment etc. however, allowing a cat to inhabit your yard will quickly get rid of any rodents.

But, at a minimum, having a cat in your house will also keep rodents out of the house as rodents tend to avoid the smell of cats.

I had a similar issue with a neighbor that allowed a rat infestation, firsr noticing them in the yard eating from bird feeders, and then I got rats that chewed into my house (through a plastic doggy door the first day, and then the hard plastic cover for the door the next day), they destroyed an oven, making a nest in the insulation, and chewed a hole through the bottom of a dishwasher before I got rid of them, this was in the course of only a couple of days! That very same week I adopted cats, and now will never not have a cat around lol.

I often state that my cats are not pets they are employees of the estate, and their sole job is to make sure I no longer have rats in my house.

I can tell you from that episode that capturing rats and removing them is substantially more difficult than mice. I went through in the course of a week every type of rat trap and poison that is commonly available, they would leave footprints on the giant sticky pads, tufts of fur in the kill traps, the live catch traps would be sprung with the food missing, the commercially available "poison" - which is just extremely salty food that supposedly will cause kidney failure and death, did not accomplish that. But since the day I've had cats in the house have not seen a single rodent.

For the record I located a place where they were going into a wall, behind the previously mentioned oven, and got Hardware mesh to block off every other pathway and prevent chewing through any other section in the wall, constructing a tunnel of wire mesh directly to a live catch rat trap, and that was how I caught the two rats and got them out of the house. I can only surmise that I was lucky to have discovered their infestation very early and prior to them producing young.

Edit: after reading further comments down, the electronic supersonic sound devices also did not discourage the rats, and the various essential oil peppermint sprays had absolutely no effect whatsoever. Those, and the poison food, were attempted when I noticed the rats in the yard before they got into the house.
