I used the bucket with sunflower seeds in it trick to catch chipmunks before. One day I came out and it looked like the chipmunck holocaust out there. Some bigger animal fell in and splashed all the chipmunck bodies out while it was escaping. Word got out and chipmuncks didn't come near my place for the rest of the year.
So yes, very effective trap.
