Help!! Anyone have suggestions...

Ok we live in a home and the home we recently bought has apparently found new renters too! RATS!! That’s right you read it righ, Help!! They are smaller like mice sizes and some are big. I’ve tried everything. Traps, bait traps, You name it! Last night I woke up to one crawling down my pillow. I could literally feel it on my hair!!😩 I’m so scared my kids are going to be attacked while sleeping. I don’t sleep at night anymore for the safety of my babies being hurt by one of them. Anyone know how to stop this dam pests from coming back? I’m desperate
