Mosquitoes cause more human suffering than any other organism. According to the World Heath Organization, more than one million people die from mosquito-borne diseases each year. While Mosquito-transmitted diseases are not common in the Midwest, every year a few people are infected with West Nile Virus, LaCrosse Encephalitis, Western Equine Encephalitis, Eastern Equine Encephalitis, or St. Louis Encephalitis. Not only do mosquitoes carry diseases that afflict humans, they also transmit several diseases and parasites to dogs and horses including dog heartworm and Eastern Equine Encephalitis. Not every mosquito bite spreads disease, but every bite is annoying.
