To address non believer posters here on this forum they are not a myth, even if you have not seen one.
The long term solution is to get rid of the food source typically citrus or bird feed.
To get rid them is to kill them. Traps or poison. The poison uses warafin, a blood thinner. They get thirsty, leave and bleed to death. Rats are very smart and are weary of new food sources. It is not very effective, but clean to use.
Traps work, the clean up is not fun. Use rat traps which are mouse traps on steroids. Place along runs in the attic.
I have killed seven, six by trap one by poison. I found the poisoned one by smell. Very distinctive. It was outside, no problem locating it.
