You don't actually inject the polyps. Cut them off and throw them away. Then the stub that is left on the rock you squirt kalk paste ON TOP of the stub and let it sit there. Like HB said, don't use a needle, just the syringe part. Mix up some kalk into a heavy liquid and suck it up in the syringe. I have used this method to kill shrooms, zoos, xenia, and GSP that I didn't like where they were growing. Never fails, just takes time.
