Sterifab is a great product. As a pre-emptive strike, should you have BB's.....get 90% alcohol, put it in a spray bottle and spray all bedding including pillows, bedframes, mattresses (especially folded corners), clothing etc including shoes. Wash all clothes in normal water however, the trick is to dry everything on HOT cycle of the dryer. It's the extreme heat which will finish BB's off.
I once managed public housing which had an integrated pest management program that included the above steps every thirty (30) days till no more bites. The alcohol kills the live bugs and any immature bugs.
These little devils are very resilient and can live dormant for years before they reappear.
Best of luck!
