Why are we dealing with this modern day scourage? It's very simple... humans have upset the balance of nature!
We feed them (right Diane!
We give them nice lush homes where they can dig and chew with impunity.
Where are their predators (the bobcat,the wolf,the hawk, the eagle,the panther, the fox)? They still have predators (cars, disease, and ME!!!), for sure,but in small numbers. Many predators are now extinct.
Take the Red Wolf for example. It is native to the South, but is very endangered.
