Chipmunks Galore

Ok, so now that there aren't that many folks running around the yeshiva property every day, the chipmunks are getting much more comfortable, inviting their friends and family and making a mess. There must be 100 munks running around the place.
So I go online to find out how to "humanely" get rid of these visitors, and I see a few ideas. First I try cayenne pepper. They are supposed to hate that smell. I spill it into all their cute little holes. Next morning I come back and smell baking, cayenne powder pie. They're loving it.
OK. Next idea is Juicy Fruit candies. The smell will make them run away. But make sure not to touch it b/c if they smell the human smell (what's that?) they won't want to smell the candy, and they won't run away. So I go around filling all their holes with about 10 boxes of Juicy Fruit. The next day, the chipmunks are there, but the neighbor Hmong kids are all vomiting from eating about 10 boxes worth of Juicy Fruit.
Next idea: baby powder. They hate the smell.....so I empty three containers of baby powder into their holes, and I go home happy. The next morning I come back, and about fifty chipmunks are pointing at me and laughing. And on the side, one of them is changing her baby, using my baby powder.
I give up.
