Did you know that as our planet warms, the habitats suitable for ticks are expanding?
According to the Environmental Protection Agency, the correlation between rising temperatures and the spread of ticks is becoming increasingly evident1. This shift not only affects the natural world but also poses heightened risks to public health through the spread of tick-borne diseases.
As ticks venture into new areas, understanding which states are most affected is crucial for prevention and awareness.
1. Pennsylvania

Pennsylvania takes the unfortunate top spot for tick activity in the U.S. This state is not only abundant in natural beauty but also in ticks, particularly those carrying Lyme disease.
In recent years, Pennsylvania has reported the highest number of Lyme disease cases (ref) in the country, a trend that shows no signs of slowing down. The dense forests and abundant wildlife create the perfect breeding ground for ticks, making outdoor activities a bit riskier.

Preventive measures are key in Pennsylvania. Residents and visitors alike are encouraged to use tick repellents, wear long sleeves and pants, and perform thorough tick checks after spending time outdoors.
2. New York
In New York, both rural and urban areas are seeing an uptick in tick populations. The state’s parks and recreational areas are common sites for tick exposure.
Staying tick-free in New York requires vigilance. Using tick repellent, sticking to the center of trails, and checking your pets for ticks are all smart strategies. Remember, ticks aren’t just a rural problem; they can be found in city parks and backyards, too. So, whether you’re exploring upstate or enjoying a local park, keep an eye out for these tiny pests.

3. New Jersey
Don’t let its size fool you; New Jersey packs a punch when it comes to tick populations. This densely populated state is a hotspot for ticks, with a high incidence of Lyme disease and other tick-borne illnesses.
New Jersey’s mix of forests, parks, and residential areas provides an ideal habitat for ticks, making them a year-round concern for residents.
4. Connecticut
Connecticut has a notorious connection to ticks, being the state where Lyme disease was first identified. The town of Lyme, in particular, became the namesake for this now well-known tick-borne illness. Connecticut’s lush landscapes and outdoor recreational areas continue to be prime territories for ticks, with residents facing a high risk of encountering these disease carriers.
To enjoy Connecticut’s beauty without the tick trouble, take precautions such as wearing light-colored clothing to spot ticks more easily and using tick control products in your yard. Awareness campaigns and community efforts also play a vital role in educating the public about the risks and preventive measures.
5. Massachusetts
Massachusetts is another state with a significant tick problem, reporting high numbers of Lyme disease, anaplasmosis, and babesiosis cases.
The state’s diverse ecosystems, from coastal areas to wooded inland regions, provide ideal habitats for different tick species. As a result, Massachusetts residents must be vigilant year-round, especially during peak tick seasons in the spring and summer.
6. Wisconsin
Wisconsin is renowned for its dairy products, but it’s also gaining notoriety for its tick population. The state’s extensive forests and farmlands are perfect habitats for ticks, leading to a significant number of tick-borne disease cases each year. Wisconsin’s health officials are particularly concerned about the spread of Lyme disease and the increasing presence of the lone star tick, a species not traditionally found in the state.
7. Minnesota
Minnesota’s beautiful landscapes and abundant waterways make it a haven for outdoor enthusiasts. Unfortunately, it’s also a haven for ticks. The state contends with a large number of ticks and associated diseases, particularly in its wilderness areas.
Understanding & Combating the Tick Threat
While ticks are a natural part of many ecosystems, their expansion due to climate change requires enhanced vigilance and preventive measures. Here are some effective strategies to reduce the risk of tick bites:
- Regular Yard Maintenance: Keep your lawn mowed and bushes trimmed. Clear leaf litter and tall grasses where ticks thrive.
- Protective Clothing: When in tick-prone areas, wear long sleeves and pants. Light-colored clothing can make it easier to spot ticks.
- Use of Repellents: Apply tick repellents that contain DEET, permethrin, or picaridin to clothing and exposed skin.
- Tick Checks: After spending time outdoors, thoroughly check yourself, children, and pets for ticks. Pay attention to underarms, in and around ears, inside the belly button, behind knees, and on the hairline and scalp.
Staying Informed & Prepared
As ticks continue to pose a significant health threat, staying informed about prevention techniques and the latest research is key. Awareness and proactive measures can significantly reduce the risk of tick-borne diseases.
By understanding the factors that contribute to the spread of ticks, such as climate change, and taking appropriate actions, we can better protect ourselves and our communities.
