Do you carry those in your survival kit?Shooting and using lurchers would be my preferred method.
Even using them as a "whip" snare would be difficult!! To be effective, any snare needs to run freely!! Even if they did manage to trap "small game" it would be doubtful that a quick kill would result I'd forget the idea. Also, I wouldn't consider carrying zip-ties in my survival kit when paracord or brass wire will do far more jobs than a zip-tie !!

Cable tie it to a tree?Also, even if you could get it to work surely you'd have difficulty securely attaching the other end to something?
Ha!
In all seriousness though, if you think of a cable tie it's a single loop. If you're using that loop as a snare, how do you attach the other end? It's a plastic tape, so you can't really tie it to anything...
