Permaculture controls for small outdoor rodents

Paul and I are working on the Animal Care badge for the PEP system.  We're detailing out some options for people to use when attempting to mitigate/eliminate small outdoor rodents.  Here's our list, can you add some more ideas???

Create snake habitat
Plants that encourage cats
Get a cat
Get a rat terrier
Attract two different birds that eat rodents
- Describe the species and how you’re attracting them
- Probably building housing
- Perches for raptors
Plants that discourage rodents
Pulse hogs/chickens/turkeys/etc. through an area with too many rodents
Put out more food for rodents (thus attracting predators)
Reduce food for rodents

Although destructive,  mowing also reduces habitat and hiding places for them

Interesting approach James!  

Makes me also think about making "DMZ" or "No man's land" areas so they won't want to cross exposed areas for fear of getting picked up by a hawk...
