I presume you mean sweeps of the city by boat? The looting is not a good thing, but to tend to it in such a massive way is like swatting at a fly when a mountain lion is chasing you.

I mean setting up boat roadblocks at every major intersection and sending out boat patrols. Remove everyone who is seen and investigate buildings where vermin are suspected holed up.
