The best thing I have used (after first trying the smoke bombs and sprays several times - hideous and toxic process) is completely non invasive parasitic trichogramma wasps. They are microscopically small (about 1mm) and lay their eggs inside the moth eggs. When the wasp larvae hatches (I think) it eats the moth larvae.
When the moths have all gone, the wasps die out - not that you even knew they were there.
It's an expensive process to commit to if you have a large house but there's no poison or toxins involved, you still use the pheromone cards to monitor and several rounds of the wasps keeps the moths under control. I had an a bad infestation of moths a few years ago but after a couple of years of moths every month in the summer, I am almost (almost!) moth-free.
The National Trust have been using them in their historic buildings

Here's the company I use - might be best calling them to see if it's worth introducing wasps now given that the moths go a bit quiet in winter (though I suppose the larvae are still munching their way through your woollens all year round).
