My favorite and most productive method was using a plastic pickle bucket with a fish wired to the back of the bucket. in the opening, I cut two notches to placed the cocked springs of a 220 conibear. I used some wire to keep anything that lived from dragging my bucket away. In two seasons using one bucket right out in plain sight I caught 35 feral house cats, 3 skunks, 20+ coons, a mink. and a beaver yes, a big beaver, by the head. Nothing was ever found alive, and nothing got away.
It was a lot of fun and the nearby neighbors thanked me for doing it.
If I was younger and could get around like I used to, I would do it again. I almost forgot-----I caught a hen Mallard there also.

I also used that same set up catching cats that were eating my son's chickens at night.

The pickle bucket was one of the 5 gallon variety---a similar bucket like a paint bucket would be the same. The 220's jaws filled the opening perfectly.
