In South Florida, American dog ticks pose a significant risk to both pets and humans. These ticks are particularly concerning because both adults and nymphs can transmit serious diseases, including Tularemia and Rocky Mountain Spotted Fever (RMSF). RMSF is a potentially life-threatening condition that can cause severe symptoms such as respiratory issues, vomiting, rash, fever, and abdominal pain.
Given these risks, it’s important for South Florida residents to be aware of the dangers posed by American dog ticks. In this post, we cover the risks associated with American dog ticks and provide practical tips on how to safeguard your pets and family from their potential threats.
The American dog tick (Dermacentor variabilis) is a common tick species found throughout the United States, including South Florida. Known for being a prime carrier of various diseases, this tick primarily infests dogs but can also affect other mammals, including humans.
Size: American dog ticks are medium to large compared to other tick species. Adult females can reach up to 1/2 inch (13 mm) in length when fully engorged with blood. Males are slightly smaller but can still be quite noticeable.
Color: These ticks are typically reddish-brown with a distinctive white or grayish pattern on their back. This coloration helps in identifying them, especially when they are not yet engorged.
Shape: The American dog tick has a flat, oval-shaped body that becomes more rounded and engorged after feeding. It has eight legs and a noticeable head (capitulum) that can be seen protruding from the body.
Mobility: American dog ticks are adept at climbing onto hosts but are not strong fliers. They use a behavior known as “questing,” where they climb onto vegetation and wait with extended legs to grasp onto a passing host.
Active Hours: These ticks are most active during the warmer months, from early spring to late summer, though they can be present year-round in some areas. They are particularly active during periods of high humidity and warmth. American dog ticks are often found in grassy and brushy areas, as well as in areas with tall vegetation. They are commonly encountered in outdoor environments but can also be found in indoor spaces if brought in by pets.
Life Cycle
Behavior
Feeding Habits—American dog ticks attach to a host and feed on blood for several hours to a couple of days. During feeding, they inject saliva containing anticoagulants to facilitate blood flow, which can also transmit pathogens.
Infestation Patterns—These ticks are commonly found in grassy and brushy areas. They are less likely to infest indoor environments compared to some other tick species but can be brought indoors on pets.
Disease Transmission
American dog ticks are known for carrying several diseases, including Rocky Mountain Spotted Fever (RMSF) and Tularemia. RMSF can cause severe health issues such as fever, rash, and abdominal pain. While these diseases are more common in certain regions, it is important to be aware of the risks in your area.
