Weird bugs in my house!?

Ok so in the in upper floor where the bedrooms etc are. There are black and orange lady bug and there's also some big bug that looks like a fat worm but is also black and orange. They start out as a black thing and then looks like a small worm then becomes bigger and fatter... i seems to be the only one who sees them... The babies are everywhere on the beds and etc... My mom just vaccum the room a few days before... now they are growing again -.- i told my mom the day i found out but she keep saying that she'll vaccum and use a water mop thingy to get rid of them... but i really think it wont work... they seem to be growing faster and developing more now... i'm really scared... i have to sleep in the couch because i cant live with them any longer... i asked to get a pest control but they said they will just use a water mop thingy, since the floor is always wet...
