Bird Lice Symptoms

Bird mites, often called bird lice, spread between birds through physical contact. Parasites of the spider and tick family, many species of bird mites are smaller than a flea. Unfortunately, these mites will bite humans. The good news is that mite bites are not associated with the transmission of any infectious disease, and knowing the symptoms can bring faster treatment and prevent bite-related complications in both birds and humans.

Bird Symptoms

• Birds suffering with mites often appear restless, preening excessively. Certain mites cause holes or a lacelike appearance to a bird's wing feathers. Skin irritation, weight loss and loss of feathers also may result from mite bites. Occasionally, the bird may cough and breathe with an open mouth.

  Any of these symptoms in a pet bird warrant a trip to the veterinarian, as some mite infestations result in death if left untreated.

Human Symptoms

• Symptoms of bird mite bites in humans range from mild discomfort to decreased health and, in rare cases, even death. Bird mites cause severe skin irritation due to the saliva injected during the bite. Itching and swelling often occur as well a general sensation of something crawling all over your body. Sometimes straight red lines appear just under the skin, while reddish dots, called blood spots, rise from the skin surface. Fiber material painfully emerging from your skin is another sign of mite bites. Intestinal discomfort and fatigue also may occur after multiple bites. Seek medical attention if any combination of these symptoms appears.

Prevention

• Preventing wild birds from building nests in or near your home is the best way to prevent bird mites. Block openings in eaves or roof cavities, and be vigilant about removing nests from gutters, window sills and chimneys. Use insect repellents when outdoors, and consult a professional exterminator at the first sign of an infestation.
