How do you treat bird mites on cockatiel?

If it is scaly face mites, then I was told to rub petroleum jelly on the cere and feet. If it is red mites in the feathers then you can have the vet give you medicine or you can try the mite spray sold at the pet store. I have a parakete who had unusual symptoms so I started doing research, and this is what I learned along the way. But, if your bird seems uncomfortable, then I reccommend you take it the vet to make sure.
