Lone star ticks are found throughout the southeastern and south-central states, thefe North Carolina and South Carolina. They will feed readily on humans, and other animals, including dogs and cats. Although they /23166.txt transmit Rocky Mountain spotted fever, lone star thers are not as likely to transmit the disease as American dog ticks.
Avoid the risk by contacting our pest control experts. Lone Star Ticks. Pest Identification:. Solid brown; females possess a white star-like dot in the middle of onrth backs. Body Structure. Flat body with eight legs. Like other ticks, the lone star tick is parasitic and requires blood of a host animal to reproduce. Males, who may mate with several females, die after mating. Likewise, females die after they have laid their eggs.
After feeding on the host, the seed tick will fall to the ground, molt and emerge as a nymph with 8 legs. The nymph repeats this process, and finally emerges as an adult. The entire life cycle may take up to 3 years to complete. Lone star ticks live nrth wooded environments and can be found anywhere animals feed or rest.
In general, young lone star ticks feed on small mammals, birds, and rodents, whereas nymphs and adults will feed on cattle, horses are there lone star ticks in north carolina - are there lone star ticks in north carolina deer.
Larva, nymphs, and adults all will feed on tiicks blood. На этой странице feeding, the lone star tick attaches its barbed mouthparts to the host and injects an anticoagulant to allow blood to ricks.
Like other ticks, they are vector pests and can transmit pathogens to a host, including bacteria that cause Rocky Mountain Spotted Fever. Often, the bite of a lone star tick tlcks will go undetected. Commonly Active. If spending time in wooded areas around your home, spray your clothing and shoes with a DEET-containing pest repellent.
If you experience nausea, vomiting, disorientation, profuse sweating, rash or onset of paralysis, seek medical attention immediately. If you are concerned about lone star ticks around your home, please consult a pest control professional. Find out more about tick control and elimination.

For most ticks, each blood meal is taken from a different type of host. Ticks are usually most active in the spring, summer, and fall; however, the adults of some species are active in the winter. When they seek a blood meal, ticks engage in "questing" behavior. Figure 2 ticks move from leaf litter or from a crack or crevice along a building foundation, or from another protected area to grass or shrubs where they attach themselves to an animal as it passes. If a host is not found by fall, most species of ticks move into sheltered sites where they become inactive until spring.
Once a tick is on a host, it crawls upward in search of a place on the skin where it can attach to take a blood meal. In addition, the tick produces a glue to hold the mouthparts in place. The female mates while attached to a host and usually feeds for 8 to 12 days until it is "engorged" full.
By the time it finishes feeding, the female may increase in weight by times Figure 3. A male tick may attach, but it does not feed as long as the female. The male tick may mate several times before dying.
After mating and feeding, the female tick drops to the ground where it lays a mass of eggs in a secluded place such as in a crevice or under leaf litter. Shortly after laying an egg mass, which may contain thousands of eggs, the female dies.
The eggs hatch in about two weeks, and the life cycle begins again. Depending upon the species of tick, the life cycle may take as little as a few months or as much as two years. The adult American dog tick, Dermacentor variabilis , Figure 4 is active in the spring, summer, and fall. It lives along woodland paths, in recreational parks, farm pastures, wastelands, and other shrubby habitats in rural and suburban areas of North Carolina.
In each stage of its life cycle, this tick may feed on a different animal. For example, the larvae feed only on white-footed field mice and meadow voles or pine voles, whereas nymphs prefer medium-sized mammals such as opossum or raccoons. Adults prefer humans and dogs as hosts. However, this species does not transmit Lyme disease. The American dog tick is found throughout North Carolina, but it is most common in the Piedmont area.
Rhipicephalus sanguineous , the brown dog tick Figure 5 occurs throughout North Carolina and may be active year round. In all stages, it feeds almost exclusively on dogs and rarely attacks people. Brown dog tick females may lay egg masses in cracks and crevices along building foundations, in pet kennels, and in homes.
After a few weeks, you may find several thousand larvae climbing on walls, draperies, or furniture. When uncontrolled in kennels, populations of the brown dog tick may grow to extremely high levels. All stages of Amblyomma americanum , the lone star tick, Figure 6 readily feed on people and large wild or domestic animals such as deer and dogs.
Adults and nymphs are abundant in the spring and summer months. The mite-like larvae of this species, commonly called seed ticks, are abundant in the fall. In this stage, the lone star tick readily attacks humans. This tick is found in habitats similar to those of the American dog tick. However, this disease is not caused by the same organism that causes Lyme Disease nor has it been linked to the same arthritic, neurological, or chronic symptoms associated with Lyme Disease.
The lone star tick also transmits bacteria that cause erhlichiosis. It occurs predominantly in the coastal plain, but it may be found in the North Carolina Piedmont.
Recent research has also tied the lone star tick to the "alpha-gal allergy" where the tick bite can result in the person developing an allergy to mammal meat beef, pork, lamb, venison, rabbit, etc. Larvae and nymphs of Ixodes scapularis , the black-legged tick Figure 7 , feed on lizards and small mammals. The nymphs and adults attack small and larger mammals including dogs and deer. Adults are active in late fall, in early spring, and in winter when temperatures rise above freezing.
The black-legged tick is found in the same habitats and regions of North Carolina as the lone star tick. It is the vector transmitter of the bacterium that causes Lyme disease. Also known as tick typhus, Rocky Mountain spotted fever is caused by a bacteria-like microorganism, Rickettsia rickettsii.
Rocky Mountain spotted fever rickettsiae are acquired by an American dog tick when it takes a blood meal from an infected animal. These bacteria are not harmful to most wild and domestic animals, but they are extremely pathogenic to humans and dogs. Rocky Mountain spotted fever is normally a disease of wild animals, but people can be infected while camping or hiking in tick-infested areas if they are bitten by an infected tick. In addition, pets may carry an infected tick into the family living area.
The disease organisms can also be passed through the egg of an infected tick and from stage to stage in the life cycle. Fortunately, only a small percentage of American dog ticks found in nature are infected.
Symptoms of Rocky Mountain spotted fever include headache, fever, chills, aches, pains, and sometimes nausea. These symptoms are usually accompanied by a rash that starts on the wrists and ankles. Early treatment of Rocky Mountain spotted fever with antibiotics can prevent severe illness, a person exhibiting any of these symptoms 2 to 14 days after a tick bite should consult a physician at once. If left untreated, Rocky Mountain spotted fever can cause death.
Lyme disease is caused by a spiral-shaped bacterium called a spirochete , Borrelia burgdorferi. The bacterium is transmitted through the bite of an infected tick. Lyme disease was recognized as a distinct disease in after several children, living close to each other in the town of Old Lyme, Connecticut, developed arthritis. The disease is prevalent in the northeastern United States where the black-legged tick, lxodes scapularis formerly called the deer tick, Ixodes damnini is the vector of the Lyme disease spirochete.
The black-legged tick in the Southeast does not tend to bite humans and as a result many fewer cases of Lyme disease are found.
The lone star tick does readily attack humans, but only a small number of spirochete-infected ticks have been collected in the Southeast.
Like Rocky Mountain spotted fever, Lyme disease is indigenous to wild animals. Lyme disease has been divided into three clinical stages. Stage I involves a rash and flu-like symptoms. Within 30 days of infection, a characteristic rash " erythema migrans" forms at the site of the tick bite. The rash can vary in size from 1 to 18 inches.
Later, secondary blotchlike skin lesions may occur away from the site of the bite as the spirochete organism spreads. The rash is usually accompanied by fatigue, a headache, a stiff neck, muscle aches and pains, and a general feeling of discomfort. Stage II , which occurs during the next several weeks, includes cardiac and neurological symptoms. Lyme disease is emerging in North Carolina. Studies have identified cases, the vector tick Ixodes scapularis, and the bacteria, Borrelia burgdorferi, a spirochete related to Treponema pallidum, the spirochete which causes syphilis.
Most patients have a normal small red, itchy, local reaction to tick bites, especially the lone star. Lyme disease diagnosis, testing, chronicity, and treatment is complex and controversial.
The causative organism is not known in spite of on-going research by the CDC and others. The lone star tick, widely distributed in the coastal plain and piedmont of North Carolina, is aggressive and all life stages readily bite humans.
Deaths are usually due to delayed recognition and treatment. Ehrlichiosis may be quite prevalent in the Piedmont. Studies have suggested that reports underestimate the true burden of disease. Complete protection is not possible. Environmental tick control methods are not practical or affordable for everyone and no personal prevention method offers infallible protection. The easiest method is to scotch tape the tick to an index card recording the date and place on the body. Most studies show that ticks need to feed for several hours or even days before infective agents can be transmitted, though the amount of time is controversial and varies with the tick and the pathogen.
North Carolina Public Health Pest Management has initiated tick education, awareness, collection and testing programs thanks to recent funding from the General Assembly, although this funding may be in jeopardy due to economic conditions. Work is also underway to ascertain which counties may become endemic for Lyme disease. Prevention of tick-borne diseases requires a comprehensive multi-disciplinary approach. Improving disease reporting by clinicians: the effect of an internet-based intervention.
