Ticks are small arachnids that feed on the blood of humans and animals. While ticks themselves are not harmful, they can transmit serious diseases like Lyme disease through their bites. Therefore, it is important to take precautions to prevent tick bites when spending time outdoors in tick habitats. One popular way to try to deter ticks is by wearing light colored clothing, particularly white or khaki. But does clothing color actually make a difference in keeping ticks at bay?
Why Ticks Bite Humans
Ticks wait on the tips of grass and bushes for a host, often a small rodent, to brush up against them. When the host brushes the vegetation, the tick quickly climbs aboard and finds an area of soft skin in which to bite. The tick then inserts its feeding tube and can stay attached for several days depending on the tick species, feeding on blood.
Some key reasons ticks bite and feed on humans:
– Ticks cannot fly or jump. They rely on hosts brushing up against them to hitch a ride. When humans enter tick habitat, we become potential hosts.
– Ticks detect hosts through sensing body heat, carbon dioxide, vibrations, and smells. When you walk through tick territory, they can detect your presence through these cues.
– Ticks need blood meals to progress to their next life stage and reproduce. Blood provides them with high energy protein and iron.
– Female ticks need large blood meals to produce eggs. They become engorged with blood, often to the size of a small grape.
– Larval and nymphal ticks are very small, often the size of a poppy seed, making them easy to miss so they can latch on without detection.
Do Light Colored Clothes Repel Ticks?
Many sources claim that wearing light colored clothing can help prevent tick bites. The theory behind this is that ticks will be more visible against a light background, making it easier to spot and remove them before they bite. Light clothing is also believed to make it easier to see small dark nymphs and larvae.
Additionally, there is some research that suggests ticks are attracted to the carbon dioxide (CO2) we exhale. Dark clothing may absorb more heat, increasing the CO2 being emitted around your body. Light clothing may allow CO2 to dissipate more rapidly.
However, there are flaws with this theory:

While light clothing has some potential benefits, there is no definitive scientific research that proves it repels ticks or reduces bites. In laboratory choice tests between dark and light enclosed chambers, there was no preference exhibited by ticks. They do not appear to be attracted to darker colors or objectively repelled by lighter colors.
Even though light clothing might make ticks more visible, it does not stop them from climbing aboard or biting. Most lightweight summer fabrics like cotton and linen provide easy grabbing points for tick mouthparts. This allows them to clamber up pant legs and latch onto skin.
Overall, while light long pants and sleeves might help spot ticks, they should not be relied on to prevent bites. Additional repellents and prevention should be used.
What Color Clothing Repels Ticks Best?
Since light colored clothing alone does not guarantee tick bite protection, you may wonder if other colors fare better. Here is an overview of how different clothing colors influence ticks:
| Color | Effectiveness |
|---|---|
| White or khaki | May help spot ticks but does not repel. No scientific studies proving colors deter ticks. |
| Blues and greens | Unlikely to repel ticks. Easy colors for ticks to spot and crawl on. |
| Black or dark colors | No evidence showing increased tick attraction. Dark clothing warms the body but significance is unclear. |
| Tans and browns | Provide some camouflage but ticks detect by CO2, heat, vibration. |
| Red and oranges | No known repelling ability. |
There is no color that has been proven to effectively repel ticks. Even though they do not see color as humans do, they likely can still perceive contrast and shades through their sensory pits. This allows them to spot and climb onto any color of clothing.
Some additional points on clothing color:
– **Camouflage patterns** that match the environment may reduce a person’s visibility to ticks slightly. But the carbon dioxide and heat emitted outweighs any potential camouflaging.
– **Dark browns, tans, and greens** that match vegetation and dirt likely offer some degree of camouflaging from ticks. But again, they still detect hosts through sensing heat, CO2, movement, and vibrations.
– Clothing patterns and shades make **no difference** in repelling ticks since they detect hosts through other means.
– There is some speculation that the bright colors like **reds, oranges, and yellows** may attract tick attention slightly since they notice contrasts. However, no studies have proven increased attraction.
So in summary, while light colors may slightly increase your awareness of ticks, no clothing colors deter tick biting or attachment. The color itself does not seem to influence ticks when seeking their next blood meal.
Do Clothing Fabrics Make a Difference?
More important than color when preventing tick bites is the type of clothing fabric:
Smooth Fabrics
– Sleek and smooth fabrics like windbreakers and rain jackets make it more difficult for ticks to attach and climb. Their smooth surfaces provide less grip and friction.
– Nylon, polyester, and vinyl are examples of slick fabrics.
– Ticks have an easier time clinging to textured, knitted, and soft materials.
Treated Clothing
– Clothes treated with insect repellents containing permethrin or pyrethroids provide protection. These bind tightly to fabrics and resist multiple washings.
– Factory-treated clothes may state they offer tick bite protection. Look for EPA-registered insect shield clothing.
– Do not apply repellents meant for skin to your clothes.
Tightly Woven Fabrics
– Tightly woven fabrics like denim are harder for ticks to puncture to reach skin.
– Materials like cotton/poly blends and wool are more difficult to bite through.
So in summary, clothes made of smooth, tightly woven, and chemically treated fabrics provide the best protection against ticks. The material has more impact than the color. Prioritize clothes made of tightly bound synthetic and blended materials. Treat clothing with permethrin for enhanced repelling.
What Areas Should Be Covered to Prevent Tick Bites?
Since ticks crawl from low vegetation onto hosts, the lower legs, ankles, and shoes are at highest risk of tick contact. When outdoors in tick habitat during their active seasons, these areas should be covered:
– **Shoes/boots** – Wear closed toe shoes with higher ankles. Tuck pants into socks or boots.
– **Ankles** – Ankle socks do not provide protection. Wear high crew socks and tuck pants into socks if possible.
– **Lower legs** – Wear long pants and avoid shorts. Tuck pants into socks or boots.
– **Waist** – Tuck in shirt and wear belt to close gaps at waistline.
– **Armpits** – Wear snug fitting shirts to avoid openings at armpits that ticks could crawl through.
– **Neck** – Collared shirts help block tick access to neck. Hoods provide additional protection.
– **Head** – Wear hat to protect head and hair and spot any crawling ticks.
The most critical areas to cover are shoes, ankles, lower legs, and waist. Ensuring socks, pants, and shirts overlap can eliminate access points for ticks to grab onto skin. Take precautions on arms and head as well when practical. Change clothes immediately after being outdoors to check for and remove any clinging ticks.
What Clothing Should You Avoid in Tick Areas?
Some types of apparel are higher risk for tick bites and attachment. Avoid these clothes when spending time in known tick zones:
– Shorts
– Ankle socks
– Sandals/flip-flops
– Tank tops
– Exposed ankle boots
– V-neck shirts
– Pencil skirts
– Dresses with gap at waistline
– Baggy shirt and pants
Any clothes that expose lower legs, ankles, feet, armpits, waist, and neck increase vulnerability to tick bites. Opt for long sleeves and pants instead tucked into boots or socks.
How Should You Wear Protective Clothing?
To maximize protective clothing:
– **Tuck in** shirt and **blouse waist** of pants to prevent skin exposure.
– **Wear high crew socks** and **tuck** long pants into them if possible.
– Choose **tightly woven and smooth fabrics** like denim, nylon, linen, canvas, polyester.
– **Avoid loose baggy clothes** – tight fit helps block access points.
– **Consider insect shield clothes** treated with permethrin for extra repelling.
– **Roll sleeves and pants** for hot weather to keep fabric tight to skin.
– **Overlap** where sleeves and pants meet gloves and socks.
– **Change clothes** after being outdoors to check for ticks.
Wearing clothes tightly secured in layers provides best results. Smooth tightly woven fabrics are ideal. Check for ticks immediately after potential exposure and shower within 2 hours.
Summary
In summary, while light colored clothing can help spot ticks, no clothing color or pattern definitively deters tick biting. More important is the clothing type. Smooth, tightly woven fabrics like denim and linen make it harder for ticks to latch on. Chemical treatments like permethrin offer additional protection. Covering legs, ankles, waistline, and neck eliminates tick access points. Take precautions year round in tick regions and perform tick checks after being outdoors. With smart protective clothing choices, you can reduce your risk of tick bites and associated diseases.
