What are Ticks Attracted To?

Ticks are tiny arachnids that are parasitic and feed on the blood of humans and animals. They are well-known for transmitting diseases such as Lyme disease, babesiosis, and Rocky Mountain spotted fever. Ticks are usually found in grassy and wooded areas and tend to attach themselves to their hosts by crawling up grass blades or clinging to clothing or fur. However we still ask ourselves — what are ticks attracted to? In this piece, we will examine the factors that influence ticks when it comes to searching for a host.

Top 7 Tick Attractants

1- Heat

Ticks are drawn to heat. They can sense the warmth and moisture emanating from potential hosts and use it to locate their prey. Consequently, they are more active during the warmer months when temperatures are higher. Additionally, ticks are attracted to body parts with higher temperatures, such as the scalp, armpits, and groin. This is because these areas are generally covered with thick hair or clothing, which traps heat and moisture and creates a microclimate ideal for ticks.

2- Carbon Dioxide

Ticks are also attracted to carbon dioxide, which is generated when animals and humans breathe. They can detect carbon dioxide from a distance of up to 50 feet away, making it easier for them to locate a host. Ticks are more active in areas where there are more animals, such as parks or wooded areas. They are also attracted to places where there is more human activity, such as near hiking trails or camping sites.

3- Motion

Ticks are attracted to movement. When a potential host walks by, the movement can catch the tick’s attention and prompt it to climb onto the host. This is why ticks usually attach themselves to the lower legs of humans and animals, as these areas are more likely to come into contact with grass and foliage that moves as the host walks by. Ticks can also sense vibrations, which can indicate the movement of a potential host. Consequently, they may be attracted to areas near roads or other sources of vibration.

4- Smell

Ticks use their chemical receptors to sense the odors of their hosts. Different tick species have distinct chemical receptors that help them identify the chemical compounds in sweat, skin oils, and other bodily fluids that can assist them in locating a host. This is the reason why certain animals or humans are more appealing to ticks. For instance, the black-legged tick, a known transmitter of Lyme disease, is more frequently found on deer than other animals.

5 – Color

Ticks may exhibit attraction to specific colors. They may show preference for lighter colors, like beige, white, or light blue, which are more reflective and can enhance the visibility of a potential host. Conversely, darker colors like black or dark blue, which are more absorbent, can make it difficult for ticks to detect a host and thus may be less attractive to them.

6 – Moisture

Ticks are drawn to moisture as they rely on a humid habitat to thrive. This is why they are more active during periods of elevated humidity. Ticks are equipped with the ability to detect the moisture on a potential host’s skin, which enables them to locate their prey. As a result, ticks are more frequently found in areas of the body where there is higher moisture content, such as around the ears or in the groin area.

7 – Host behavior

Lastly, the behavior of their hosts also attracts ticks. For instance, they tend to be more attracted to hosts that are immobile or at rest since it makes it easier for them to attach without being detected. Moreover, ticks may prefer hosts that are asleep as they are less likely to notice the tick crawling on them. Additionally, hosts with compromised immune systems may be more attractive to ticks as they may be less capable of detecting and removing them.

Note that not all ticks are attracted to the same factors. Different types of ticks may be drawn to different hosts and environments. For instance, the Lone Star tick has a preference for humans, whereas the American dog tick is frequently found on dogs.

Tick Bite Prevention

Here are some revised tips to avoid ticks and prevent tick bites:

To reduce the amount of exposed skin, consider wearing long-sleeved shirts and pants. Tuck your pants into your socks.
Before going outdoors, apply insect repellent that contains effective ingredients such as DEET. Be sure to apply it to your skin and clothing.
Stay on marked trails and avoid walking through tall grass or wooded areas, especially during peak tick season.
Do daily tick checks, especially if you have been in an area where ticks are prevalent. Pay attention to areas such as the scalp, behind the ears, and around the waistband.
Remove any ticks you find as soon as possible. Using tweezers, grasp the tick as close to the skin as possible and pull upward with steady, even pressure. After removing the tick, wash the bite area with soap and water and monitor it for any signs of infection.
