Behavior, Diet & Habits
Understanding Deer Ticks
Deer ticks, primarily found in the eastern half of the United States, are also known as blacklegged ticks, while often mistaken for brown dog ticks. Named for their propensity to feed on white-tailed deer, deer ticks may also feed on other large mammals as hosts, including humans. Humans are considered accidental hosts and may contract Lyme disease from bites. Livestock and domestic animals can also be hosts.
Adult Length & Color: These ticks are brownish in color but may change to rust or brown-red in hue following feeding. Adult males are smaller than females and are uniformly brown in color. Unfed adult female blacklegged ticks are approximately 3 - 5 mm long and are colored red and brown. Females that are engorged with a blood meal appear darker and are about 10 mm long. In most cases, a deer tick is usually half the size of the common American dog tick.
Adult Bodies & Legs: Like other ticks, their bodies are flattened, and after becoming engorged by a blood meal, the body expands substantially. They possess eight legs as adults.
Nymphs: Nymphs are between 1-2 mm long (about pin-head sized) with eight legs.
Larvae: larvae are less than 1 mm long (about poppy seed sized) and have only 6 legs.
Deer ticks are found in many locations where their preferred host, the white-tailed deer, dwell. They are present throughout the majority of the eastern United States and tend to live in wooded areas and along trails in forests.
Deer ticks reside on the tips of grass and leaves along these trails, enabling them to crawl directly onto the skin or fur of a passing host. Some of these trails may be found in suburban areas where forests meet subdivisions. Deer and other animals are often active in these areas.
All three of the deer tick's development stages require blood meals from hosts. They attach themselves to and feed on one host during the larval stage, another during the nymphal stage and a third during their adult stage. Larvae and nymphs both molt after feeding.
Deer ticks take approximately two years to complete their life cycles. Development depends on environment and the availability of hosts. Under favorable conditions, they may be capable of developing in less than one year.
After laying eggs, female deer ticks die. However, one female is capable of laying up to 3,000 eggs. Six-legged larvae emerge from these eggs and begin to search for a host. Larvae feed for approximately four days before dropping to the ground to molt into nymphs. Resulting nymphs have eight legs and search again for hosts. They, too, will feed and molt into adults.
Deer ticks begin life as eggs and develop through larval and nymphal stages before becoming adults. Females lay eggs in suitable areas close to vegetation.
Larval and nymphal deer ticks prefer small hosts and are more likely to feed on rodents than on large animals. The larval feeding stage is responsible for the tick's contraction of most diseases like Lyme disease, while these diseases are transferred to humans and livestock during the nymphal and adult stages.
Lyme disease is a debilitating disease caused by the bacterium Borrelia burgdorferi. Deer ticks are the most common vectors of this bacterium. Lyme disease is easily transmitted to human and animal hosts through deer tick bites.
Although deer ticks do not jump or fly, they remain in grassy areas frequented by dogs, cats, and other warm-blooded hosts. As these hosts brush against the grass, deer ticks cling to the coat of the animal and begin to feed. Because they potentially bite a different host for the next meal, infected ticks are capable of spreading Lyme disease quickly throughout a population.
The small size of the deer tick is also a factor in the prevalence of Lyme disease. Their bites are not painful, and most victims do not notice them until they have become engorged from prolonged feeding.
Due to the arachnid's small size, it can be difficult to locate the pest on its host. These parasites attach themselves to hosts and hide within the fur, hair, or feathers.
Removing Ticks on Humans
On humans, deer ticks are commonly found in the areas near the nape of the neck or along the lower scalp. Extreme care must be exercised when removing these pests from the skin of any host, as bodily fluids may be released if the tick is crushed or punctured, which increases the risk of disease transmission. The most efficient removal method includes the use of tweezers or forceps. It is important to remove the entire tick, including its embedded mouthparts.
