floatr, I haven't found anything that deters them. Even though the neighborhood cats chase them, they come back. I went to Tractor Supply Company and got a trap for $35. I used apple slices for bait, and I think I caught 9 total. Took them and released them in a nature area by a lake 10 miles from the house. Humane, nice area for them to live, and they won't come back.
