Prepare for unexpected vet bills

What is Tassel Foot?

These mites are invisible to the naked eye, but they cause a crusty white growth on your bird’s feet and legs causing severe itching and restlessness. These mites also attack the facial area especially around the beak and eyes and can concentrate around the vent.

Left untreated, complications compromising your pet’s health can occur which can eventually result in death. If your bird gets infested with these mites, any other birds housed with it will need treatment as well.

Tassel foot, or scaly leg disease, is caused by the scaly leg mite (knemidocoptes mutans) that burrow into the limbs and toes of your bird.

Causes of Tassel Foot in Birds

  • The mites spend their whole life cycle on a bird – they are described as an eight-legged mite related to spiders and ticks but so much smaller 
  • They form tunnels in the top layer of your bird’s skin by burrowing through the tissue 
  • Contagious between birds so if you have more than one bird, all will need treatment
  • If your bird has a deficiency in vitamin A it can make it vulnerable to this condition 
  • A seed only diet is low in vitamin A which can produce lowered immunity
  • Lowered immunity makes your bird more susceptible to the mites 
  • Nest box infestation – often this can remain latent for a long time 
  • Direct contact between birds can transmit the mites

Diagnosis of Tassel Foot in Birds

At first, you may not be aware that your bird is suffering from this infestation. Then you may notice the legs and feet look a bit red and perhaps swollen, while your bird is acting differently and is a bit agitated. Then you will start to see the typical white lesions or crustiness starting to build up on your bird in the affected area. A trip to your avian veterinarian specialist is advisable to be able to treat this condition before it creates serious health related issues. Heavy crusting can cause your bird's claws to become deformed and overgrown. It can also result in lameness, and the inability to perch. 

Your avian specialist will take scrapings of the affected parts of your bird’s body, and he will also check other areas such as the beak, wing tips and vent to ensure the mites have not spread further. Under a microscope, the mites are visible and easily confirmed as the cause of your bird’s discomfort. This diagnosis rules out other similar causes such as insect bites and infection. While your specialist is performing his physical examination, he will ask about the typical daily diet for your bird and may make suggestions for supplements to assist your bird’s health, such as Vitamin A which promotes increased resistance to infection and provides some protection against some parasites.

Treatment of Tassel Foot in Birds

Tassel foot in your bird can be treated in several ways. Ivermectin is an insecticide which is widely used by veterinarians and is only available through their clinics. Other options available described below, may be utilised but it is best to have the approval of your veterinarian before moving forward. Avomectin and Moxidectin are products that may be available through reputable pet and bird stores without a prescription. Another option is a product called Scatt, which is proving to be very effective. It has a residual effect with one dose being effective for up to three weeks. Products such as Scalex Mite and Lice Spray for Birds are available at your local store and is effective in removing the scales of crustiness that build up. Don’t try to pick off the scales unless they are treated and have softened, or you could cause bleeding sores on your bird. 

After consultation with and on the advice of your veterinarian, you may attempt to treat your bird by rubbing olive oil, baby oil, or paraffin oil on the feet and legs to suffocate the mites and soften the crusts for removal. Be careful how much oil you put on, or your bird’s feathers can become coated, and it is hard to remove. Moderation is the key. A holistic approach is to treat your bird with grapefruit seed extract (GSE). Using five to ten drops in one tablespoon of distilled water, you can dab this onto the affected area. You can also use one drop of GSE to every eight ounces of drinking water to treat from the inside out. But never use it full strength on your bird, and carefully avoid the eyes.

Recovery of Tassel Foot in Birds

It may take a few weeks to get the mite infestation under control, but follow your avian specialist’s directions to complete the treatment. If you have more than one bird, they will all need treating to ensure the scaly mite is eradicated. Although the mites live on your bird, they can also burrow into the cracks in the timber inside a cage such as wooden perches and remain latent for several months before coming out to reinfect your bird again.

Thorough cleaning with a nontoxic cleaning material, and replacing any wooden structures will ensure that your birds home is safe and free from mites. If your bird is given antibiotics to prevent or heal any secondary bacterial infections, make sure you continue the treatment until the very end to ensure its effectiveness.

Severe White Scaly Growths On Feet

My elderly parents has been taking care of a canary and did not notice the severe growths on the bird's feet. It is so severe that it has sadly deformed the Right foot and formed a "spur" at the back which curls upwards of about at least a cm long. We have been treating the feet with AKWA Avian medic scaly face and leg treatment. Would like to know if it is possible to cut a bit of the spur away? Not sure if the mites grow a blood supply from canary's foot. And also do not want to hurt the poor canary. It is bad enough already as it is and looks uncomfortable. See picture below

Thank you for your question. I apologize for the delay, this venue is not set up for urgent emails. I would not cut any of that away without anesthesia, as I think it would be quite painful. If they are still having problems, It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.
