Every year, millions of people in the United States and the United Kingdom are confronted with an unpleasant reality: tick bites are becoming increasingly common. Recent statistics reveal that approximately 31 million Americans fall victim to these blood-sucking pests annually, a figure that has been steadily climbing for over a decade. With tick populations expanding and Lyme disease cases surging, experts are sounding the alarm on the importance of vigilance and proactive measures against these parasites.
A Growing Concern
In the United States, emergency room visits related to tick bites have surged this year, drawing the attention of health officials and environmental scientists alike. According to Vett Lloyd, a biology professor at Mount Allison University in New Brunswick, the expansion of tick populations can be directly linked to climate change and human encroachment on natural habitats.
“Milder winters and warmer summers improve the survival rates of ticks,” Lloyd explains. “As we continue to develop land that was once forested, we inadvertently create prime habitats for ticks to thrive.”
This environmental shift is not only alarming but also significantly impacts human health, as ticks are known carriers of various diseases, including Lyme disease.
The Spread of Lyme Disease
The implications are dire. In the US, the incidence of Lyme disease has risen by 69% in 2022 compared to the annual averages recorded between 2017 and 2019. Similarly, the UK has experienced a more than 20% increase in Lyme disease cases from 2024 to 2025. The proliferation of ticks is exacerbated by the increasing populations of their primary hosts—mice and deer—who are also thriving in suburban environments.
“This is largely due to human activity,” Lloyd asserts. “Our lifestyle choices are directly contributing to the expansion of pathogens that can be transmitted to humans.”
How to Safeguard Against Tick Bites
The key to avoiding the health risks associated with ticks is awareness and preventive measures.
Tick Checks: Your First Line of Defence
Ticks prefer dark, moist environments, often hiding in leaf litter or tall grasses until they can latch onto a passing host. After spending time outdoors, it’s crucial to perform a thorough tick check.
“Look for ticks in areas where they are likely to bite, such as behind the ears, in the armpits, and around the groin,” advises Lloyd. “If you find a tick before it has begun to feed, you can significantly reduce the risk of disease transmission.”
Showering promptly after outdoor activities can help wash away any ticks that may not have latched on yet.
What to Do If Bitten
If you find yourself bitten, it’s essential to remove the tick as soon as possible. Dr. Charlotte Mao, a pediatric infectious disease physician with the Bay Area Lyme Foundation, recommends using fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
“Pull upward with steady, even pressure,” Mao instructs. “You want to ensure that the mouth parts do not remain embedded in the skin.”
After removal, cleanse the bite area thoroughly and monitor for any unusual symptoms, such as fever or rash, which could indicate a tick-borne illness. If you notice a circular rash resembling a target, seek medical advice immediately, as this may signal the onset of Lyme disease.
Preventing Future Bites
To minimise the risk of tick encounters, the CDC advises using insect repellents approved by the Environmental Protection Agency, wearing protective clothing, and staying on the centre paths when hiking.
Moreover, homeowners can take proactive steps to reduce tick habitats in their own backyards. Regularly mowing the lawn, trimming vegetation, and using acaricides can significantly diminish tick populations.
Erika Machtinger, a medical and veterinary entomologist, highlights the effectiveness of tick tubes—cardboard rolls filled with permethrin-treated cotton that mice can use to line their nests, providing indirect protection against ticks.
Why it Matters
The rising incidence of tick bites and the diseases they carry is a pressing public health concern. As climate change continues to reshape ecosystems, understanding how to protect ourselves from these threats is essential. With proactive measures and increased awareness, individuals can take charge of their health and safety in the face of this growing problem. By staying informed and vigilant, we can significantly reduce the risk of tick-borne diseases, protecting both ourselves and our communities.
