>They can’t teleport through solid material. If the interior of your home is sealed, they cannot get in.
Bold statement, You know that rats can chew through cement and pretty much anything else?

There’s also a question of how thick the material, and how motivated the rat. Can rats make a dent in bricks? Yes. Is a single rat going to chew a hole all the way through a brick wall just to see that’s on the other side? I’m no rodent behavior expert, but I doubt it.
More to the point (at least according to YouTube exterminators) rats will only chew through things if they have a reason to. That is why you seal holes with silicone caulk after the copper wool: to prevent the smell of food from drawing rats in.
In any case, I can only tell you what treatment we applied and what the results were. There is a lot of information on the internet about how to prevent rat ingress in apartments and buildings. Based on my experience, that information seems accurate. But another approach is to assume nothing can be done and live with periodic rat infestations.
