Terminix Ranks Top 25 Most Tick-Infested U.S. States Amid High Tick Activity.

Terminix has released a list of the top 25 most tick-infested US states, based on 2024 pest management data. States with warm climates, high humidity, and green spaces, such as California, Florida, and New York, are at the top of the list due to increased tick activity and risk of tick-borne illnesses. This report provides valuable insight into geography and climate's impact on tick populations nationwide.

Emergency room visits for tick bites have surged to record levels in 2025, particularly in the Northeast. According to data from the Centers for Disease Control and Prevention (CDC), tick bite-related emergency department visits in June 2025 reached 229 per 100,000 visits, up from 167 per 100,000 visits in June 2024 [1]. This increase can be attributed to several factors, including record-high tick populations and a longer tick season due to climate change [1].

The surge in tick populations is not confined to the Northeast. Terminix has released a list of the top 25 most tick-infested US states based on 2024 pest management data. States with warm climates, high humidity, and green spaces, such as California, Florida, and New York, are at the top of the list due to increased tick activity and the risk of tick-borne illnesses [2]. This report provides valuable insight into the geography and climate's impact on tick populations nationwide.

Tick bites can lead to a variety of illnesses, including Lyme disease, babesiosis, and anaplasmosis, among others. The CDC has warned that ticks transmit more viruses and diseases than any other animal, making this a significant public health concern [1]. Dr. Dennis Bente, a professor of microbiology and immunology at the University of Texas Medical Branch, highlighted the "sneaky opportunist" nature of ticks, noting that they "hang out in bushes or on top of grasses and wait for pets or people to walk by" [1].

To mitigate the risk of tick-borne diseases, health experts recommend preventive measures such as wearing long-sleeved clothing, using insect repellant, and performing regular tick checks. These measures are particularly important in areas with high tick populations, such as the top 25 tick-infested states [2]. Dr. Thomas Mather, a University of Rhode Island entomology professor and director of TickEncounter, emphasized the importance of understanding the different types of ticks and the diseases they can transmit [2].

The financial implications of this trend are significant. Increased tick populations can lead to higher medical costs, both for individuals and the healthcare system. Additionally, the economic impact on tourism and outdoor recreation industries in tick-infested states could be substantial. Investors and financial professionals should closely monitor this trend and consider its potential impact on various sectors of the economy.
