She followed them around all the time and disguised herself with sunglasses and a hoodie. In the 3rd (Perfect) or 4th (Unbelievable) book, there are rumblings in the news about someone sneaking around. That person was called "the Rosewood Stalker." The only thing people knew was that the person had blond hair. The Liars catch very quick glimpses of this person spying on them a couple of times. So while Mona did do a lot of undercover work, she wasn't exactly the best at it.
