Believe it or not, Louisiana has ticks. While it may not be as abudant as in othe parts of the country, we do have risk of ticks and diseases caused by tick bites. All photos below are from the Centers for Disease Control and Prevention website.
Scientific Name: Amblyomma americanum
Habitat: Lone star ticks are typically found in wooded areas, grasslands, and along the edges of forests. They prefer warm and humid environments, which are abundant in Louisiana.
Scientific Name: Ixodes scapularis
Habitat: Black-legged ticks prefer wooded and grassy areas with dense vegetation, where they can quest for hosts by climbing onto blades of grass or other vegetation and waiting for a passing host. While Louisiana has suitable habitat for black-legged ticks in some regions, they are not as prevalent as in states farther north.
Scientific Name: Dermacentor variabilis
Habitat: American dog ticks prefer habitats with tall grasses, brush, and wooded areas, where they can quest for hosts. They are often found in areas frequented by wild and domestic animals, such as fields, meadows, and along hiking trails.
Scientific Name: Rhipicephalus sanguineus
Habitat: Brown dog ticks are often found in urban and suburban areas, particularly in environments where dogs are present. They can infest kennels, dog houses, and other areas where dogs rest or congregate. However, they can also be found in rural settings.
Scientific Name: Amblyomma maculatum
Habitat: Gulf Coast ticks prefer coastal and marshy habitats, including grasslands, scrublands, and areas with dense vegetation. They are often found in coastal dunes, marshes, and brushy areas near water sources.
Scientific Name: Haemaphysalis longicornis
NOTE: Haemaphysalis longicornis was first discovered in the United States in New Jersey in 2017. Since then, it has been reported in several states, primarily in the eastern and southeastern regions. However, we have not yet detected this species in Louisiana.
At LSU, we are interested in establishing current distribution maps of ticks in Louisiana. We would be delighted to receive any tick specimens from you. Our goal is to establish where different tick species occur in the state. This will also help us to better assess any future potential tick-borne disease risk in Louisiana. We will also post other tick identification resources as well. (might not be accessible on some smartphones).
