This leads to an intensive trapping campaign. If one is able to catch a rat within 24 hours of it gaining ingress that is ideal; after that time-period the rat becomes accustomed to its surroundings and more wily.
Adults are much more difficult to deal with. They are smart animals, and will often go into pseudo-hibernation for as much as a week after gaining entry before manifesting their presence by knocking spice jars off the shelf or gnawing at cardboard food containers.
Some 20-odd years ago I carried out an amateur survey and determined there to be around 12 rats per acre on this island. The terrain is very rough with sharp rocks, numerous cavities and the whole covered by dense vegetation. Nevertheless Barn owls, who hunt in pairs, are able to derive a ready supply of protein from this source.
We have both Rattus rattus and Rattus norvegicus; a fully grown male Rattus norvegicus is fearsome to behold and beyond the capability of the standard spring-type rat-trap. Fortunately males are far less common than females.

I don't envy you at all -- to my knowledge only ever had two in our place -- the first one survived in the floor cavity for quite some time by consuming copious quatities of our plastic plumbing creating several leaks -- some quite impressive. Finally found it's way out. Second one managed to squeeze through a hole where the plumbing entered the premises. Took up residence under the bath and died there shortly after - either from poison, or starvation we know not -- it did however not smell too sweet for a while, and then it's maggots turned into very large flies. Electric bug zapper "tennis" raquet proved their downfall. Since then we have used very coarse steel wool compacted around all wiring and plumbing at their various entry points and that has seemed to do the trick.
