The ABSOLUTE BEST bait for killies beleive it or not is Salami. Yep, you read correctly, sliced Salami. You can also use Kilbosi or any other greasy meat. The oils that come of the meat drives them nuts. As for time, I fill my trap in 1 hour with a few slices (2 or 3) of Salami in about 1' of water.
