In the heat of the summer, mosquitoes can easily complete their life cycle in under a week making standing water in horse troughs prime mosquito sources. We ask horse owners to be diligent in making sure horse troughs are emptied or cleaned at least once a week. In attempt to help protect horses and minimize mosquitoes we have a dedicated technician who can give advice, information, and/or (at the owners-request) a briquet that can provide mosquito control for up to 150 days. We are aware of the location of most horses in our District and attempt to remind owners about maintenance with annual doorhangers.

Like humans, horses are also susceptible to West Nile virus but have an effective vaccine available. We highly recommend all horse owners have their horses vaccinated for West Nile virus by a licensed veterinarian.
