Bird Mites

[Quakerella]

Hi an welcome to PP.

So sorry to hear of the problem you are having with mites.

Did you only find one on her tail or were there more?
You cleaned her cage, did you give her a bath as well?
You will also need to thoroughly clean and disinfect the room where the cage is, inclucing the carpets, curtains, bed, furniture, etc.

I would start looking elsewhere for the issue and not at your bird. Carefully look inside and outside your house, do you have any bird's nests nearby?
Look at all the brickwork, gutters soffits, everything. Look inside your house at any little cracks, windows, doors, attic openings etc.
Many times these little critters are coming from outside the house.

You need to pinpoint the problem area before you will be able to get rid of them.

Good luck and keep us posted.
