steam cleaners that get really hot also work. But just everyone be forewarned that getting rid of them will be either incredibly time consuming or expensive in most cases...and if you don't think you will do well with them think about it now while you can get rid of clutter etc. before anything hits. A somewhat spartan house is going to be easier to treat...exterminators have to be able to reach baseboards, crevices, move furniture etc. And they mkae you take all your clothing etc. out of the house..then people pack it up and put it in storage units...oh dear..some are going to escape so check anything ou have in storage. mg
