Exterminators have the equipment to make this happen in your space because they now use heat to kill bed bugs. Someone else on the list can tell you the specifics and affirm that this works for silverfish. Of course, no treatment will keep insects from coming back if the material is damp, and making sure all the mold is dead is also necessary.
