I tried the tagger gun; didn't like the holes, plus if you have to cut one of the tags because it's in your way, then you have to dig around and be sure you find the bottom part cause you don't want to run over it. Then I bent the needle and quit using it. Spray is good, but you do have to be careful about overspray, and it does stink. I'm thinking I'm going to try pinmoors.
