Controlling Mosquitoes and Dangerous Disease Risk

Published on: 5/13/2025

Key Takeaways

Mosquitoes aren’t just a nuisance; they transmit dangerous diseases affecting people, pets, horses and livestock, with risks ranging from West Nile Virus to heartworm and major livestock productivity loss.
One acre can harbor up to 1 million mosquito eggs, making prevention essential. Remove standing water sources like unused troughs, tarps and wheelbarrows to eliminate breeding habits.
Protect pets with heartworm preventives, shield horses with core vaccinations and help livestock by reducing mosquito pressure around barns and pens.
Use barn fans to create moving air, which mosquitoes avoid, and treat properties with proven control products like Spartan Mosquito Pro Tech.
Stay proactive year-round to reduce disease exposure and to keep your animals, and yourself, comfortable and safe outdoors.

Enjoying time on the patio; hiking with your furry friend; riding your horse; finishing up barn chores. What do all of these have in common?

None of them are nearly as pleasant when you’re being swarmed with mosquitoes.

More than an annoyance, mosquitoes carry deadly diseases impacting people, pets, horses and livestock. Some of the risks include:

People are at risk for several mosquito-transmitted diseases, including West Nile Virus, Malaria and Zika Virus, which causes serious birth defects such as microcephaly. Babies with microcephaly have smaller heads and often have smaller brains that might not have properly developed.
Pets are at significant risk for heartworm disease, a deadly disease transmitted by mosquitoes. Protect pets with heartworm medications, providing nearly 100 percent effectiveness against the disease.
Horses are threatened with mortality rates up to 90 percent from mosquito-transmitted diseases, which include West Nile virus, Eastern equine encephalomyelitis and Western equine encephalomyelitis. Vaccinations against disease can protect horses from grave risk.
Livestock can be plagued with extensive blood loss, reduced productivity and even death when faced with large populations of mosquitoes.

One acre of land can house 1 million mosquito eggs. Help eliminate the mosquito population by removing mosquito-breeding habitats, such as anything that can hold water, like unused troughs, tarps and wheelbarrows. If your yard or barn area has any low-lying areas that collect water after rainfall, be sure to fill these in. If you have horses and livestock, hang fans throughout your barns, as mosquitoes typically avoid moving air. Additionally, deploy proven mosquito prevention products, such as the Spartan Mosquito Pro Tech, to help defeat the enemy.
