Ticks don’t fly, jump, or blow around with the wind. They are small, simple in their approach to locating a host, and very patient. Their purpose in life is to propagate their species. They don’t feed often but when they do they can acquire disease agents from one host and pass those disease agents to another host at a later feeding. Their sensory organs are complex and they can detect trace amounts of gases such as carbon dioxide produced by warm blooded animals. They can sense the potential host’s presence from long distances and even select their ambush site based upon their ability to identify paths that are well traveled. Ticks generally are not born with disease agents but rather acquire them during feeding. They then pass the disease onto other animals during subsequent feedings. Infections that are transmitted from animals to humans are called zoonotic diseases.
