A large number of flying insects emerge with the heat each summer, and they can turn what should be long luxurious days in the ring, field or trails into painful, frustrating or itchy endeavours! While irritation may seem like a minimal concern, excessive flies can cause stress in horses, which can lead to reduced performance and malnutrition. Not only can insects be bothersome, but bug bites can cause a variety of allergic type skin reactions in many horses.

Scientists learned in recent years why zebras have black and white stripes — to avoid biting flies. But a study published on February 20, 2019 in the journal PLOS ONE probes the question further: What is it about stripes that actually disrupts a biting fly’s ability to land on a zebra and suck its blood? Professor Tim Caro of the University of California, Davis, and University of Bristol’s Martin How led a series of new experiments to better understand how stripes manipulate the behaviour of biting flies as they attempt to come in to land on zebras.

Adjustments to your horse care routines will likely be necessary during the winter months, and should be tailored to your climate and the needs of each individual horse. Here are some tips to help keep your horse in health this winter.
