I saw a post concerning the use of Ivomectin for killing ear mites. We too have found it very effective and relatively easy to use. Just a note of caution,though. Ivometcin is toxic. The dilution given to us by our vet, Dr. Dutton, is 10 MG/ML. The directions call for ONE drop in each ear; then repeat ONCE again in TWO WEEKS. Of course the dosage will depend on dilution. It does lose potency once mixed. It should be kept in a dark bottle. Before using the Ivomectin solution, you should clean the ears of wax. We use Chlorhexiderm Flush for that task. Dick B. Not a vet. Please talk to your vet prior to using Ivomectin. [Posted in FML issue 1552]
