What kind of ferns are we talking about and where do you live? I've never known them to be that aggressive by any means and I have a number of types of them.
They are usually susceptible to at least once type of weed killer. The first step is to properly ID them.
The other thing you can do is just mow them down and them cover them with thick news paper, then cover that with mulch or top soil.
