Code Orange - Call Your Vet at Their First Available Office Hours

    Occasionally, you might notice strange insects, mites or lice on your horse. You may not be sure what they are, or whether they are of importance.


    Assess the horse’s general health using the Whole Horse Exam (WHE), and share your findings with your vet. Specifically, consider whether you notice other signs of illness or abnormalities such as itchiness, hair loss, blood spots or irritation of any kind.

    Try to determine the number of bugs and their distribution on the horse. How many are there and where are they located? What do they look like?

    If possible, wearing gloves, collect a few in a small glass jar or bottle to show your vet. Alternatively, take a photo of the bugs and/or the affected area and share it with your vet for discussion.


    Vets should be able to identify the offending insect. Identification will guide the need for concern and treatment. Depending on the type of insect, your vet may recommend that you spray your horse with a conventional fly spray or other treatments.
