Think football stadium size pits, for at least width and length.
Depth could be up to 15 foot deep.
What about areas with a layer of quick dry concrete and an overhead sprinkler syslem.
Pits with acid in them.
Alligators

What about a trap that would funnel them into falling into a wood chipper!!
The wood chipper idea sounds messy as hell. Besides, if it jams up who goes down to fix it?
Using a prison as an encampment is a good idea. But remember, if they know living people (food) are inside they will gather outside in ever growing number.
