Don't hesitate. Buy as many of these http://www.amazon.co.uk/Clothes-Moth-Killer-Smoke-Bombs/dp/B0127QD8B2/ as you need to fumigate the whole house. Cover or disable the smoke alarms and kill every last one of the fuckers, and all their eggs and larvae in one hit.
You'll want to be out of the house for several hours afterwards to give the poison time to do its job, and then when you come back, open every window and get some fresh air in.
