Ticks in Pennsylvania: A Comprehensive Guide

Pennsylvania is home to several species of ticks, some of which can transmit dangerous diseases to humans and animals. In this article, we will explore the most common tick species in Pennsylvania, their characteristics, the diseases they carry, and their common hosts. We will also discuss the three most prevalent tick-transmitted diseases in the state: Rocky Mountain Spotted Fever, Lyme Disease, and Tularemia. By understanding the risks associated with these ticks, you can take steps to protect yourself and your loved ones.

American Dog Tick

Scientific name: Dermacentor variabilis Color: Brown Diseases: Rocky Mountain Spotted Fever Common hosts: Dogs, mice, raccoons, people

The American Dog Tick is widely distributed across Pennsylvania and can be found in wooded areas, shrubbery, and farmlands. This tick species goes through different stages throughout its life cycle, with each stage feeding on different types of animals. The larvae typically attach to small mammals like voles and field mice, while the nymphs prefer raccoons and opossums. As adults, American Dog Ticks feed on larger mammals, including dogs and humans. While this tick does not transmit Lyme Disease, it is a known vector for Rocky Mountain Spotted Fever.

Groundhog Tick

Scientific name: Ixodes cookei Color: Light brown, tan Diseases: Powassan virus Common hosts: Groundhogs, people, small birds

The Groundhog Tick, also known as the Woodchuck Tick, is another common species found in Pennsylvania. These ticks primarily feed on groundhogs, making them less likely to carry Lyme Disease. Instead, they are known carriers of the Powassan virus. Groundhog ticks can also attach to small birds and occasionally bite humans. With a light brown color and rounded body, they are distinguishable from other tick species in the area. While they were more prevalent in Pennsylvania before the 1990s, they have since been outnumbered by American Dog Ticks and Black-legged Ticks.

Lone Star Tick

Scientific name: Amblyomma americanum Color: Brown round body Diseases: Alpha-gal allergy, Southern Tick Associated Rash Common hosts: Coyotes, dogs, people, deer

The Lone Star Tick is one of the most common species found in Pennsylvania. Active during the spring and summer seasons, Lone Star Tick larvae are also present in large numbers during the fall. They are known carriers of the Southern Tick Associated Rash Infection, which exhibits similar symptoms to Lyme Disease. Lone Star Ticks can attach to both humans and large animals such as dogs, deer, and coyotes. In addition to the rash infection, bites from these ticks have also been linked to causing a meat allergy known as alpha-gal allergy.

Black-legged Tick

Scientific name: Ixodes scapularis Color: Brown and tan Diseases: Lyme Disease Common hosts: Dogs, deer, lizards

The Black-legged Tick, also known as the Deer Tick, is prevalent throughout Pennsylvania all year round, including the winter season. These ticks are the main carriers of Lyme Disease in the state. They feed on large mammals like deer and dogs, as well as lizards and other animals depending on their life stage. Adult Black-legged Ticks primarily feed on large mammals, while nymphs and larvae target small mammals and reptiles. These ticks are active in Pennsylvania as long as temperatures stay above freezing. Nymphs are most active during the summer months.

Asian Longhorned Tick

Scientific name: Haemaphysalis longicornis Color: Light brown Diseases: Powassan virus Common hosts: Horses, birds, deer

The Asian Longhorned Tick is a less common tick species found in Pennsylvania. While it is not as prolific in spreading diseases as other ticks in the state, it has been known to transmit the Powassan virus. The choice of hosts for this tick varies based on its life stage, ranging from small to large mammals. Nymphs may be found on birds, while adults could be found on deer, sheep, and horses. While only a few cases have been recorded in Pennsylvania, the Asian Longhorned Tick is an invasive species expected to spread rapidly. These ticks have a light brown to tan coloring.

Common Tick-Transmitted Diseases

Ticks found in Pennsylvania can transmit several diseases to both humans and animals. The three most common tick-transmitted diseases in the state are Rocky Mountain Spotted Fever, Lyme Disease, and Tularemia.

Rocky Mountain Spotted Fever (RMSF)

Ticks that spread this: American Dog Tick, Lone Star Ticks Symptoms: Chills, fever, rash, headache

Rocky Mountain Spotted Fever is one of the most prevalent tick-transmitted diseases, commonly spread by American Dog Ticks and Lone Star Ticks. Infected ticks transfer the disease from animals to humans when they attach and feed for at least six hours. Symptoms usually appear 2 to 14 days after a tick bite and may include a rash, chills, fever, headache, and body aches. It is essential to seek medical treatment promptly if you suspect you have contracted RMSF, as early detection and treatment can significantly improve outcomes.

Lyme Disease

Ticks that spread this: Lone Star Tick, Black-legged Tick Symptoms: Rash, pain, memory loss, mood swings

Lyme Disease is a serious illness transmitted by various tick species, including the Lone Star Tick and Black-legged Tick. The disease presents itself in three different stages, each with its own distinct symptoms. It is most commonly transmitted by black-legged ticks and lone-star ticks, affecting both humans and animals. The initial sign of infection is often the appearance of a distinctive rash. As the disease progresses, additional symptoms may include joint and muscle pain, fatigue, neurological complications, mood changes, and memory loss. The severity and combination of symptoms can vary depending on the stage of Lyme Disease.


Ticks that spread this: Lone Star Tick, American Dog Tick, Rabbit Tick Symptoms: Chills, swollen lymph nodes, fever

Tularemia, also known as rabbit fever, is another tick-transmitted disease found in Pennsylvania. Several tick species, including Rabbit Ticks, American Dog Ticks, Lone Star Ticks, and Rocky Mountain wood ticks, can transmit Tularemia. Ticks infected with the bacteria that cause Tularemia can cause an ulcer at the site of the bite. Other symptoms may include chills, swollen lymph nodes, fever, and loss of appetite. Prompt treatment can significantly reduce the risk of complications and mortality associated with Tularemia.
