So far I have used

from scipy.interpolate import splrep, splev, sproot
import warnings
warnings.simplefilter("ignore")
but the warning message is still there.
Am I missing something ?

Is it possible to throw an exception ?

Python's warnings machinery can be used.

https://docs.python.org/2/library/warnings.html
Using warnings.simplefilter('ignore') you will completely silence the warning, and using 'error' instead will raise an exception. You may want to run this in a context, so it doesn't "leak out" on the rest of your program:
with warnings.catch_warnings():

See examples in the docs.

It isn't a warning in that sense.  sproot simply calls print. See https://github.com/scipy/scipy/blob/master/scipy/interpolate/fitpack.py#L726
