I have had 3 small outbreaks, and each time got rid of them using a rapid change in pH rather than temperature - much easier, I think. I used pure vinegar in a 10 cc syringe, and injected it right into the little critters. You have to move fast, as they retract quickly - basically start emptying the syringe just before you puncture the little beasts. Then, I followed them down their hole in the rock and emptied the syringe. I also tried it once with lemon juice - but had to do it 3x before it worked. But the vinegar has a very low pH which, if injected right into them, kills them in seconds. Cheap, too. Just be careful how you dispose of the needle. I used a regular 22gauge spinal needle about 9 cm long. Any small sharp needle would do.
