Take it to a veterinarian. There's a good chance they can determine if your hamster has ear mites. They can also prescribe a treatment for ear mites. I know this is hard to hear but a hamster is a rodent with the average life span between 1.5 -3.5 years they are one if the hardest to keep alive it's also hard to find treatments because of the abundance of hamsters and their value vs. other pets a dog would be easier to treat then a hamster. -Ex pet care associate
