Not long ago (6 weeks) I brought home a pathetic little parakeet with a severe case of mites. I also brought home her little friend who was feeding her. (How could I not bring home Hope and Faith?) Hope was so weak and unhealthy I was concerned the standard protocol of Ivermectin would kill her, it is a very strong poison! I opted to try a less agressive aproach and used vaseline instead. I would take just a smidgen of vaseline on my fingers and massaged very thin film on to all feather free areas. I paid particular attention when working around the beak and cere. The over all difference has been nothing short of amazing. She has gained weight, her little beak has a natural gloss, and she is far more active. Although Faith has never shown any indications of having mites, I also treated her as well, in the same manner, and of course both of them have been in quarantine, and will remain as such for quite some time yet.
Now, bare in mind, ivermectin is only one of the drugs capable of killing heartworms in dogs. Dogs have been known to die as a result of the treatment! I didn't want to live with a case of the cure killing this little bird. Using the vaseline was time consuming and took much longer to smother out the mites, but it worked and Hope still lives! Given the state she was in, I doubt she would have survived being poisoned. For her, I made the right decision. Each and every case is different. Your bird is most likely healthier and has gotten far better care. I am sure there should be no concerns of using a more agressive approach. However, admittedly, Hope and Faith came from a pet store, yet I did not purchase them. I went in, told the owner he was going to work with me and I was going to give her a half decent chance of living. He handed her over to me without the slightest bit of hesitation. He didn't even charge me the full ransom for Faith, which I was ready to pay. Faith was feeding Hope, and the stress of bring her to a strange place alone, well, I just didn't think she needed any more stress than could be prevented. Look at her pictures and tell me I was wrong.
