Indoor Pest Control - Urgent! Infestation in wardrobe!!

If any one can help me, please write asap.

I'd been storing some winter clothes in a wooden box under the bed, and when I got them out to wash and wear, they and the box - were covered in larvae. I suspected it was from moths, although I haven't seen any in the bedroom. The larvae is a beige-light brown colour with lots of legs and hairs. They also seem to have been shedding their skin, because I found empty "shells" all around.
That was a few months ago, and after cleaning out the box and washing the clothes I thought nothing more of it.

Then this morning, I was clearing out some clothes from my wardrobe, and found the same insects again! Now I'm going to have to systematically wash all of the clothes in the wardrobe.

But does anybody know of anything else I can do to stop them coming back?

Check out all the cracks and corners in your closet. Do you see any webbing? Have you seen any moths flying around?

You may want to put some gluetraps down and come back in a few days and see if you have caught anything.
