Ticks in Illinois

Illinois may not immediately conjure images of vast wilderness or towering mountains, but don't let its relatively flat terrain fool you. The state boasts an abundance of outdoor recreation areas that cater to a diverse range of interests, from hiking and camping to birdwatching and fishing. Unfortunately Illinois is also home to a wide variety of dangerous ticks.

Ticks that live in Illinois may include the blacklegged tick (deer tick), American dog tick, brown dog tick, Lone Star tick, Asian longhorned tick, poultry tick, Rocky Mountain wood tick, Cayenne tick, Gulf Coast tick, and Pacific Coast tick. As ticks actively expand their habitats across the United States designating defined geographical regions as the sole place of residence of any given tick is becoming a fleeting challenge.

Ticks in Illinois are a threat everywhere, from the deep forest to urban backyards. These lethal arachnids employ a behavior known as "questing", a passive strategy where they position themselves in vegetation, such as tall grasses or shrubs, and wait for a potential host to pass by.

Ticks have specialized sensory organs located on their legs, known as Haller's organs, which can detect stimuli such as heat, carbon dioxide, vibrations, and odor. When a human or animal approaches a waiting tick senses these stimuli and reacts by extending its legs outward, latching on as you pass by.

Once a tick has hitched a ride, it will crawl to a secluded location on your body, attach, and feed on your blood. Ticks secrete a unique substance that prevents you from feeling their bite, so they can feast unnoticed. Disease transmission may occur.
