To put what other people have said into perspective, consider this: A counter-missile has a wedge 10 km across. That means that it only has to get within 10 miles of the target to kill it. Now, imagine how many flechettes you would have to use to fill up a 10 km by 10 km square through which the target passes, closely space enough to kill a missile with a diameter of 1 or 2 meters.
If you put 1 flechette per square meter, you will need 1 million flechettes just to do the job of a single counter-missile. And that assumes that you are able to aim your flechette wall with the same accuracy as a counter-missile. Since counter-missiles are guided and flechettes are not, that clearly cannot happen. You might have to fill an area a thousand miles wide or more because you can't predict where the missile will be when it hits your flechette wall. You would need immense numbers of flechettes to stop one missile.
In essence, what you are proposing is similar to the autocannnon that used to be common a hundred years ago in the Honorverse. But that was before the invention of the laserhead. Autocannon can be useful against missiles that get very close to the ship, but they are not useful at the standoff ranges of laserheads.
