Annoying:
* Itching and irritation: Mosquito bites are itchy and irritating for horses, just like for humans. This can lead to scratching and rubbing, which can cause skin abrasions and infections.
* Stress: Being constantly bothered by mosquitoes can cause stress for horses, making them agitated and less willing to perform.
Dangerous:
* West Nile Virus: This virus can cause neurological problems in horses, including encephalitis (inflammation of the brain) and paralysis. Symptoms can include fever, lethargy, stumbling, and muscle tremors.
* Eastern Equine Encephalitis (EEE): This virus is even more serious than West Nile and can be fatal for horses. Symptoms include fever, lethargy, stumbling, and seizures.
* Equine Infectious Anemia (EIA): This viral disease is spread by horseflies and mosquitoes, not just mosquitoes. It can cause fever, anemia, weight loss, and death.
* Equine Piroplasmosis: This parasitic disease is spread by ticks and mosquitoes. It can cause fever, anemia, and death.
* Other diseases: Mosquitoes can also transmit other diseases to horses, such as heartworm, Lyme disease, and Zika virus.
How to Protect Horses from Mosquitoes:
* Use insect repellent: There are many insect repellents available for horses. Choose a product that is specifically formulated for horses and that contains DEET or picaridin.
* Provide shade: Mosquitoes are more active in shady areas. Make sure your horses have access to shade during the day.
* Eliminate breeding grounds: Mosquitoes breed in stagnant water. Eliminate standing water around your property by draining puddles, emptying buckets, and cleaning gutters.
* Use fly masks: Fly masks can help protect horses' faces from mosquito bites.
* Vaccinate your horses: There are vaccines available for West Nile Virus and Eastern Equine Encephalitis.
It's important to take steps to protect your horses from mosquitoes, especially during peak mosquito season. If you notice any signs of illness in your horse, contact your veterinarian immediately.
