Don't forget weird tricks gravity can pull in space (even bend light)
pinpointing a deflection over a certain distance would be useless
better would be a "tripwire" system but the size (and powerrequierments) needed
would be even bigger to make it efficient

I'd say drop mines over half the galaxy,... everything that'll try to come through
-comet or battlecruiser- would be noticed, and no longer be a problem
