I have squirrels making home in my attic roof. Every morning around 6:30am the chewing noise wakes me up!?

There are two of them, I am afraid they may raise a family up there...and the chewing noise really made me worry. I bought mouse trap, animal cage trap, there is no bite! I need help..will someone out there give me a workable advice what to do?! Don't need to tell me to get a pets control company or no need to joke with me please. I am serious to get rid of the problem! Thanks.
