If possible, remove debris from your yard or farm to help lower insect populations. Standing water and overgrown leaves, grass, and shrubbery are great breeding grounds and homes for insect pests. Using insect repellents or essential oils can also aid in preventing bites. When working outside, wear clothes with full coverage to prevent bites. It is important to take precautions for your health as many vectors carry diseases that can spread to humans. How can I protect myself from disease vectors? Taking steps to avoid warm standing water and spilled feed can also help prevent insect population growth. Secure feed containers can help protect your feed from birds, mice, and rats, which can spread disease. Using insect controls like fly traps, essential oils, and manure management can help reduce the insect burden on your farm/ranch. Rotate pastures and your grazing ground regularly to prevent the build-up of manure which can attract vectors. As the weather warms and rain increases in spring and summer, insect populations grow. There are various protections you can take to protect your herd. How can I protect my herd from disease vectors? A few VBD diseases that are a risk to people include Lyme disease, salmonellosis, and West Nile Virus. ![]() Diseases spread by vectors to animals include:īecause VBDs can spread to humans as well, you should take care to protect yourself. It is important to keep a careful eye on your health and your herd’s health. VBDs can bring risks to both livestock and humans. What are common diseases spread by vectors? Salmonellosis is a disease that can be spread by rodents and birds as well as flies. Rodents and birds also are capable of being vectors of disease. Other common vectors include fleas, filth flies, sandflies, midges, and lice. Throughout the world, mosquitoes are the most common and transmit many deadly diseases. In the U.S., the most common vector is the tick. An example of biological spread of a VBD is Lyme disease, which is carried by ticks and affects both animals and humans. The vector can then transfer the disease by putting it on or into an animal or human. Then the disease replicates or develops in the vector. Biological transmission occurs when a vector, like an insect, uptakes the pathogen. Pink eye is a VBD that is spread mechanically by flies. When disease is spread mechanically, the vector simply transports it on its contaminated body. Vector-borne diseases can be spread in two ways – mechanically and biologically. Every year there are about 700,000 human deaths from vector-borne diseases occur worldwide. ![]() The most common vectors are insects that suck blood, such as mosquitoes and ticks. Vectors are insects, rodents, birds, or other animals that can carry disease pathogens. As we move into summer and the weather gets warmer, we tend to see an increase in vector-borne diseases (VBD). ![]()
