![]() This is a dose of 50 micrograms and is at the high end of the therapeutic range and should be reserved for resistant mites. Saline dilution may have a precipitate but this does not seem to change the effectiveness. Another choice is to dilute 1:10 in saline and dose orally at 0.05mg (1 drop or 0.05ml) once every 2 weeks for 1-3 applications (some literature has up to 6 treatments needed for a difficult infestation). A disadvantage is inconsistency of absorption of active ingredients. This is simple and fast and works well in many birds. A small amount of alcohol on a swab may be necessary to view the skin through the feathers. An easy way to treat is using 0.1% Ivermectin (1:10 dilution with propylene glycol) topically on the bare skin on the lower neck over the jugular vein area using approximately one drop. Various regimens have been used and the choice can be selected due to a variety of factors – is it a single bird or flock are the birds easily handled or highly stressed what is the degree of infestation and possible resistance of the mites. This treatment has the potential to be more harmful to the birds than the mites and its use is very questionable. They can also be used to hang in the aviary but away from contact with the birds. The strip should be aired out for 1-2 days prior to use. One involves placing a No-Pest Strip (diclorvos) by the cage and covering it for an hour monitoring the birds very carefully for evidence of wobbling and toxicity. There have been a variety of treatments documented over the years. If lab work can be performed there is often an increase in a certain white blood cell called a basophil. As they are not always seen in this manner you may have to treat based on clinical signs in these birds. The mites are tiny black specks within the trachea. Birds rarely die from this but it can have a long-term effect on the flock in both health and economics.Ī positive diagnosis can be made by trans-illumination of the trachea using a pinpoint light source shining through the skin and “windpipe”. Owners and aviculturists may see a progressive loss of condition in these birds, respiratory distress, wheezing and squeaking sounds, coughing, sneezing, discharge from nares, loss of voice, gasping, and occasionally head shaking. Food and water can also be contaminated from coughing and sneezing. They can be coughed up from the trachea and swallowed and passed orally or through the stool. The life cycle of the mite is still not known but is probably spread to nestling birds from the regurgitated nutrients by the parents. A common respiratory problem seen in Gouldian finches and less frequently in canaries is caused by air sac mites (Sternastoma Tracheacolum).
