[rab] Bait. That's the only way to do it. I had an infestation in my flat (which was a conversion of 'the poor house' - ie the workhouse into six flats) and I caught 11 or 12 in traps, then got fed up of the traps going off while I was relaxing and watching telly. So I called in the council who put down bait everywhere in the building and we got rid of the whole lot. If you have them, the other flats will have them too - am I right in thinking you have a flat in a fairly old building?
