Ear Mites

WHAT ARE EAR MITES?

Ear mites are tiny infectious organisms resembling microscopic ticks. The mite can just barely be seen as a small white dot with the naked eye and usually must be detected by examination of a sample of ear wax under a microscope. Infection usually produces a characteristic dry black ear discharge commonly said to resemble coffee grounds. Because of the classical appearance of this discharge, infection is often diagnosed based on the presence of such discharge though without visual confirmation of the mite under the microscope, it is possible to be led astray. The discharge is composed of ear wax, blood, inflammatory biochemicals, and ear mites themselves.

WHAT HARM COMES FROM EAR MITE INFECTION?
The presence of the mites can generate very irritating ear infections. Skin disease can also result from infection by the ear mite.

CONTAGIOUS?
Ear mite infection is definitely contagious among cats and dogs. Humans have been reported to develop skin rashes rarely. Usually, a pet owner is extremely unlikely to experience any symptoms when their pet is infected with ear mites.

HOW TO GET RID OF THEM?
There are numerous products available for ear mite eradication. Most over-the-counter products contain insecticides which do not kill incubating mite eggs. Because of this limitation, such products must be used for at least the duration of the 21 day life cycle of the mite.

A newer approach involves the use of Ivermectin, a broad spectrum anti-parasite medication. Ivermectin is especially helpful in cases where the patient simply will not allow topical ear treatment. Ivermectin is administered in the ear (.25 cc) three days in a row.

This is a highly effective method of ear mite eradication but there are other considerations and limitations. Contact your vet. for more information or click here.
