Our expert says:
The most likely cause is a mite infection - take them to your local vet to get an avermectin product to use - this needs to be repeated every 10 - 14 days for 3 treatments. Other causes would include an allergy to the sawdust - replace with newspaper, and even a viral infection (this causes small smooth bumps on the ears, which can become quite itchy) . If viral, it usually resolves by itself in a month or two.
