Mosquitoes are an annoying and potentially dangerous pest that many people want to avoid. Their bites can leave itchy welts and in some cases transmit diseases like Zika, West Nile, malaria, and more. While there are many ways to try repelling mosquitoes, from sprays to citronella candles, one of the easiest things you can do is choose your clothing color carefully.
How Mosquitoes Use Vision to Find Targets
Mosquitoes locate hosts through different cues like carbon dioxide, body odor, heat, and movement. However, vision is one of their primary senses for detecting potential sources of blood meals from distances of up to 50 meters away. Their eyes are specially attuned to discern human shapes and colors.
Key Factors That Attract Mosquitoes
Several key factors seem to attract mosquitoes to certain colors:
Dark colors: Shades like black, red, and navy blue stand out against natural backdrops like soil, water, vegetation, and sky. Dark colors generate visual contrast that draws mosquitoes.
Heat absorption: Darker shades absorb heat, which helps mosquitoes hone in on warm-blooded targets. Lighter colors reflect more heat.
Carbon dioxide detection: Mosquitoes can sense CO2 plumes emitted by exhaled breath up to 150 feet away. Dark clothing obscures detecting those plumes.
Pattern confusion: Busy patterns and prints create visual noise that can inhibit mosquitoes from distinguishing a clear human outline. Solid blocks look more human-like.
The Mosquito-Repelling Power of Light Colors
Research into mosquito vision and behavior consistently finds that lighter shades make less appealing targets. Pale and light colors reflect heat, blend with backgrounds, and don’t boldly advertise your presence. Here’s why lighter hues help you avoid attention:
Reflect heat: Lighter fabric doesn’t retain body heat like dark material, making you less visible to mosquitoes’ thermal detection.
Camouflage outline: Pale, light colors more closely match natural hues in the environment, disguising your human shape.
Diffuse CO2 plumes: Light backgrounds around exhaled carbon dioxide make plumes harder to detect.
Minimize contrast: With less contrast against the ground and sky, light colors don’t stand out as much to mosquitoes.
| Color | Mosquito Visibility |
|---|---|
| White | Low |
| Khaki | Low |
| Beige | Low |
| Light blue | Low |
| Red | High |
| Black | High |
| Dark green | High |
This table shows some examples of colors ranked from low to high visibility to mosquitoes. Lighter shades in the white, khaki, beige, and light blue range make you far less noticeable. Darker hues like red, black, and dark green will attract more mosquito attention.
The Single Best Mosquito-Repelling Color
Out of all shades, which specific color is the very best to wear in mosquito zones? Based on multiple controlled studies, the winner is….white! Here’s why scientists say white is the top mosquito-evading color:
– Reflects the most light: Of all hues, white clothing reflects the most wavelengths of light. This creates the least possible contrast with the environment.
– Disrupts thermal detection: The white fabric blocks the most heat radiation emitted from the body, scrambling mosquitoes’ thermal tracking.
– Diffuses CO2 plumes: White provides the lightest colored backdrop to visually diffuse telltale carbon dioxide exhaled by breath.
– Matches natural hues: White clothing closely resembles shades and shapes found in nature – clouds, snow, sand, brush – better disguising human forms.
– Creates minimal movement contrast: White minimizes motion contrast with the background when walking, making it harder for mosquitoes to detect.
Studies Confirm White Delivers the Most Mosquito Protection
Controlled scientific research affirms that wearing white is definitively the best color choice for avoiding mosquitoes:
– A 2019 study published in Nature’s Scientific Reports had participants stand still in different colored clothing while trapped mosquitoes were filmed. Mosquitoes landed on black clothing at a rate of 186% more than white clothing.
– According to a 2002 study in the Annals of the Entomological Society of America, mosquitoes landed on white fabrics at the lowest frequency compared to dark brown, black, dark blue, dark green, and red fabrics which attracted the most mosquitoes.
– Research by the University of Washington in 2018 found that Aedes aegypti mosquitoes preferred landing on the darkest of 6 scaled clothing colors ranging from black to light yellow when viewing from 15 meters away.
– A 1995 study revealed mosquitoes had a landing preference on darker blue, black and red surfaces compared to lighter yellow, light blue and white surfaces.
The scientific consensus from controlled testing confirms wearing white makes you essentially invisible to mosquitoes compared to darker shades.
How to Enhance Mosquito Protection with White Clothing
To maximize the mosquito-evading power of white apparel, here are some expert tips:
– Wear lighter weight fabrics: Lightweight, breathable fabrics reflect more heat, diffuse CO2 plumes better, and reduce contrast motion.
– Choose matt finishes: White clothes with glossy, shiny finishes retain more heat alluring mosquitoes. Matt textures reflect heat better.
– Prefer loose fits: Oversized cuts allow more airflow circulation to disperse CO2 around you. Tight fits concentrate CO2 plumes.
– Add lighter accessories: Pair white outfits with hats, shoes, sunglasses in light beige, cream, khaki, tan, and light blue.
– Stay in the shade: Seeking shade avoids standing out against bright skies. Filters like netting also disguise human shapes and colors.
– Move slower and less: Excess motion creates attention-grabbing contrast. Move calmly and steadily to minimize motion heat and sounds.
