Moths love wool - but they like dirty wool more, and they hate the light, so they lay their eggs in the darkest and most undisturbed parts. The centre line is their most likely target on anything.

That level of damage also takes time to do - woollen items should be put away clean, either in something moths cannot access - a freezer is a good place, or in a sealed protective cover of some kind, and not left in the open air unless regularly - at least once every week - disturbed, brought out into the light, shaken and inspected.

Worse than moths though are carpet beetles. I hate carpet beetles.
