Uninvited Guests Overstay Welcome

We have a problem in our house. We have guests that have come uninvited and are not leaving soon. They have not manners. I have found them going through many of our things. How dare they check out our towels? When I tried to persuade one to leave my kitchen, he took offense at my words and tried to push me down. But the absolute intrusion was the one near my living room ceiling checking to see if I had swept away those spider webs. How dare she be so bold!
