Majanos are very mobile, so if you want to get rid of one (or just move it), cover it with a shell or something, so that it is very shaded but not trapped inside. It will then climb on top of whatever is shading it so that it will get closer to the light.
Then you just move whatever it is on top of and you are done! You don't have to worry about whether or not you killed it, and it's quick and easy to boot.
