Hard ticks (Ixodidae)
hard ticks ( Ixodidae ) get down as an egg that is laid by an pornographic female tick. Once the egg hatches a larva emerges that must then find and feed on a small mammal or shuttlecock ( host ). After feeding it drops to the prime from the host and goes through a molt process, emerging as a nymph.
Nymphal hard ticks then seek larger hosts, and after feeding drop off and molt into adults. The life cycle of hard ticks lasts one to two years depending on the species. The pungency of a hard tick is by and large painless, with a feed serve lasting several hours, to days, even weeks .
Soft ticks (Argasidae)
soft ticks ( Argasidae ), like hard ticks begin as an egg, hatch into a larva, feed and then molt into a nymph. Nymphal balmy ticks may go through american samoa many as seven phases as nymph, requiring a blood meal at each stagecoach. soft ticks ’ life sentence cycle lasts from months to years depending on the species. The bite is typically painless and only lasts 15-30 minutes, making it harder to detect. While both hard and soft adult ticks are easiest to identify, it is significant to note that nymphal ticks are equally capable of transmitting disease. In some areas the nymphal tick contagion rate is actually higher than the adult check mark infection pace. The follow is a list of ticks found in the United States that are known to bite and transmit disease to humans :
Know The Types of Ticks
American Dog Tick (Dermacentor variabilis)
The american pawl tick have a dark brown body. Females have an bone shield, while adult males look more mottle. The greatest risk of being bitten is from the adult females during the spring and summer months. Pathogens: This species is the primary vector of the bacteria that cause Rocky Mountain spotted fever ( ( Rickettsia rickettsii ) ). It is besides known to transmit Tularemia ( Francisella tularensis ), Ehrlichia, Anaplasma, and click paralysis. Location: This click has a broad distribution east of the Rocky Mountains, throughout the East and Gulf Coast, along the Pacific Coast, into Canada and parts of Alaska. American dog ticks are by and large found in areas with little or no tree cover, such as grandiloquent grassy fields and gloomy lying brush and twigs, ampere well as along walkways and trails .
Blacklegged “Deer” Tick (Ixodes scapularis)
This click is most well identified by its red-orange body, black shield and dark black leg. Pathogens: The deer tick is known to transmit Borrelia burgdorferi ( the agent of Lyme disease ), Borrelia mayonii ( which causes a Lyme-like illness ), Borrelia miyamotoi and Borrelia hermsii ( that both cause relapsing fever Borreliosis ), Ehrlichia muris ( ehrlichiosis ), Anaplasma phagocytophilum ( anaplasmosis ), Babesia microti ( babesiosis ), multiple species of Rickettsia, deer tick virus, and Powassan virus. This tick is besides suspected of transmitting Bartonella to humans. Location: Over the last two decades, the distribution of fink ticks has expanded. They are now found throughout the eastern U.S., big areas in the north and cardinal U.S., and the South. The northern distributions of the blacklegged click are continuing to spread in all directions from two major endemic areas in the Northeast and Upper Midwest. It ’ sulfur important to note that adult ticks will search for a server any clock when temperatures are above freeze, including winter. Blacklegged ticks are found in a across-the-board diverseness of habitat that are suitable for birds, large and humble mammals such as mice, deer, squirrel, coyotes and livestock. All animation stages can bite humans, but nymph and adult females are most normally found on people who are in contact with grass, brush, leaves, logs or pets that have been roaming the outdoors .
Brown Dog Tick (Rhipicephalus sanguineus)
The brown pawl tick is a red brown with a specialize shape in comparison to other ticks. Pathogens: All life stages of this tick can transmit Rocky Mountain spotted fever ( Rickettsia rickettsia ), Q Fever, and other rickettsioses to humans. They can besides transmit several diseases specific to dogs. Location: Dogs are the primary host for the brown frank click which is found global. The brown andiron tick can survive and breed in nature but live chiefly in and around homes with dogs ( for example, frank beds and kennels ). These ticks are adequate to of spending their entire life hertz indoors. To eradicate embrown andiron tick infestations, experts recommend : treating all pets the sign of the zodiac and yard, sanitize the pet beds and other areas the dog frequents, including the cable car. This work may take perennial applications over several months .
Groundhog Tick (Ixodes cookei)
The groundhog tick, besides known as groundhog check mark, has a light brown or blond coloring material. Pathogens: The groundhog tick is the primary vector for Powassan virus disease.
Location: This check is found throughout the eastern half of the United States. All biography stages of this click feed on a variety of warm-blooded animals, including groundhogs, skunks, squirrels, raccoons, foxes, weasels, and occasionally humans and domestic animals .
Lone Star Tick (Amblyomma americanum)
This tick is red-brown in tinge. The adult female is distinguished by a white acid or “ lone star ” on her back. Pathogens: The nymphal and adult ticks can transmit human monocytotropic ehrlichiosis ( HME ), Ehrlichiosis ( Ehrlichia chaffeensis, Ehrlichia ewingii, and Panola Mountain ehrlichia ), Rickettsiosis, Rocky Mountain spotted fever ( RMSF ), Tularemia ( Francisella tularensis ), Heartland virus, Bourbon virus, Q fever and tick paralysis, a well as Borrelia lonestari, which causes southern tick-associated foolhardy illness “ STARI, ” an illness about identical to Lyme. Location: The lone star tick is widely distributed throughout the Eastern U.S. but is most prevailing in the South. These ticks are notoriously aggressive biters, with the greatest gamble of being bitten from early spring through late Fall. Note: The bite of this tick has been associated with stay allergic reactions to the consumption of crimson kernel in some humans. This circumstance, known as “ alpha-gal ” allergy, is increasingly being recognized as a health problem throughout this tick ’ south geographic range .
Pacific Coast Tick (Dermacentor occidentalis)
The Pacific Coast click has a mottled brown-black tinge. Pathogens: All life stages of this tick can transmit Rocky Mountain spotted fever to humans and their pets. It can besides transmit Colorado click fever virus ( CTFV ), Pacific Coast check fever ( spotted fever Rickettesia 364D ), the Rickettsia of Q fever and Rickettsia philippi ( a spotted fever rickettsial disease ), vitamin a well as the bacteria that causes Tularemia. The bite of this tick causes a hurt that is normally mistaken for other biting insects and spiders. Location: The Pacific coast tick is prevailing in the Southwestern U.S. It has a broad crop from Baja Mexico into Oregon. The Pacific Coast ticks are the most park tick found throughout California .
Rocky Mountain Wood Tick (Dermacentor andersoni)
These ticks are red-brown and look identical like to american english frump ticks. The adult males have a cream-colored carapace. Pathogens: This click is the primary coil vector of the Colorado click fever virus ( CTFV ), american samoa well as the agents of Rocky Mountain spotted fever ( Rickettsia rickettsii ), Q fever and tularemia. The saliva of the Rocky Mountain wood tick contains a neurotoxin that can occasionally cause tick paralysis in humans and pets. The toxin takes anywhere from 24-72 hours to dissipate after click removal. Location: Rocky Mountain woodwind ticks are found chiefly in scrublands, lightly wooded areas, open grasslands, and along trails. They occupy the area between the easterly and western distribution of the American dog tick and extend into Canada. In the U.S., their geographic distribution is broadly restricted to higher elevations above 4,000 feet. These ticks can be active from January through November, but their activity diminishes during the hot and dry mid-summer period. Adult wood ticks can be found questing about knee-high on the tips of vegetation. They prefer to feed on culture medium to large mammals, but can survive up to 600 days without prey .
Soft Ticks (Ornithodoros)
soft ticks do not have a unvoiced blast and are shaped like a bombastic raisin. Pathogens: This tick is the elementary vector of two principal union american agents of tick-borne relapse fever ( TBRF ) known as Borrelia hermsii and Borrelia turicatae. Location: soft ticks are distributed wide throughout the western United States, including Texas, and are approximately limited to coniferous forests at elevations between 900 – 2,000 meters above ocean degree. People normally are bitten as they sleep in rustic mountain cabins that have been previously infested with rodents. In Texas, TBRF may be associated with the exploration of caves. Because the bite is painless victims are much unaware they have been bitten. Documented outbreaks of TBRF have occurred at national parks and vacation cabins in Colorado, Arizona, and the Lake Tahoe area in California .
Western Blacklegged Tick (Ixodes pacificus)
These ticks have a red soundbox with a black shield and black leg. Pathogens: This click transmits Lyme disease, Borrelia miyamotoi disease ( a get worse fever Borreliosis ), babesiosis, ehrlichiosis, and human granulocytic anaplasmosis ( HGA ). It besides is suspected of transmitting Bartonella to humans. Although all life stages of this click can bite, nymphs and adult females are thought to be the chief cause of illness in humans.

Location: While the western blacklegged tick is most prevailing in California, being established in 55 out of 58 counties, it can besides be found in five other westerly states : Oregon, Washington, Arizona, Nevada and Utah. Studies indicate the geographic distribution of the western blacklegged check mark has not expanded over the past two decades, although active surveillance efforts for this check mark outside California have been very limited. The tick can be found along deer trails in grassy coastal regions, dense woodlands, amongst fallen leaves or fir needles, and on fallen logs or branches. Researchers have besides found nymph on the undersides of wooden park benches and tables. Squirrel, lizards, mouse, vole, fox, coyote and deer are common hosts for the western blacklegged tick. Like all ticks, migrating birds act as a long outdistance transporter. While the majority of cases of Lyme disease are diagnosed in the Northeast and Midwest, it is authoritative to note that some Lyme-endemic counties in California are larger than the states of Rhode Island and Delaware, and the nymphal check infection pace is comparable to or higher than hyperendemic areas in the northeastern U.S .
