Flies tend to dislike or avoid colors like yellow and red, with yellow often used in fly traps as a repellent and red lights attracting fewer bugs overall, while they are strongly attracted to dark colors (black, brown, navy) and blue light. So, for keeping them away, think sunny yellows and bright pastels, and use blue lights to draw them to traps away from you.
TIL that flies are three times more attracted to the color blue than to yellow, and that yellow actually seems to repels flies.
Each color has its own wave frequency, but flies have only two kinds of color receptor cells. This means they have trouble distinguishing between colors, for instance discerning between yellow and white. Insects cannot see the color red, which is the lowest color frequency humans can see.
Our behavioral experiments using the TSLT demonstrated that yellow was significantly less attractive verging on repellent to house flies, either as a solid color in comparison to white or blue or as lines on an attractive blue background.
Because bugs see colors on the UV spectrum, they cannot register hues of green or blue. Painters even use blue paint to repel bees and wasps.
Flies hate strong, pungent smells, especially essential oils like lavender, eucalyptus, peppermint, and lemongrass, due to compounds like linalool that overwhelm their senses; other scents they dislike include strong herbs like basil and rosemary, and even things like cinnamon and citronella. These natural scents can be used in diffusers, sprays, or by planting them to create a fly-free zone, as flies prefer filth and are repelled by these clean, sharp aromas.
Tips for getting through black fly season:
Black flies love dark colors. Navy blue, green, black and brown are the most attractive colors to black flies. The best shades to wear during black fly season are pastels- especially very light yellow, blue, and green.
Dr Roger Santer, from Aberystwyth University's department of life sciences who led the work, said entomological field studies have long shown that flies are attracted to blue, which has led to traps across the world being made in that colour.
Fly Repellent Clothing
Insect Shield permethrin-treated apparel provides a reliable defense against flies. With options for Men, Women, Girls, Boys, and an array of accessories and gear, clothing with built-in permethrin can help prevent fly bites.
For homeowners who prefer chemical-free methods, several natural remedies can eliminate flies instantly: Vinegar and dish soap traps: Attracts and drowns flies. Herbs and plants: Basil, mint, and bay leaves repel flies immediately.
After surveying research into the neuroscience and behavior of insects, the authors wrote that insects were unlikely to feel pain, noting that their nervous systems are different from those of vertebrates.
Turn Off Lights
Chances are you've seen them buzzing towards your light fixtures at night. This is because flies are positively phototactic, which means they're naturally attracted to light. Turn off outdoor lights at night when possible to avoid attracting them inside as soon as the nearest door opens.
Clothing. Wear light-colored clothing because black flies are attracted to dark colors. Wear hats, pants and long-sleeved shirts for maximum skin protection, because black flies don't bite through clothing.
Again, dryer sheets often contain linalool, which is derived from lavender and other flowers, and beta-citronellol, which comes from citronella. These compounds do have some insect-repelling properties. However, the concentration in dryer sheets may not be strong enough to be truly effective.
Vinegar attracts, not repels flies; however, a container with vinegar and dish soap will function as an attractant trap as the vinegar lures flies to enter the trap and the dish soap will cause the flies to sink and die. Oils like lavender, mint, lemongrass, clove, rosemary and eucalyptus may help in repelling flies.
“While it's more widely known for repelling mosquitoes, catnip can also help deter flies when used in oil form or planted around your home,” she says. Other scents that could help banish flies and other insects include rosemary, lemongrass, cloves, and citronella.
Just a bit on the areas of exposed skin (or a shot on the collar and hat) will keep them from landing. Citronella wrinkles the nose of a blackfly, as does Vicks VapoRub.

Well studies have shown that the color yellow is the number one color that repels flies. Unfortunately you would need to completely surround your home in yellow light bulbs for it to have any real effect.
A sudden influx of flies usually means they've found a nearby breeding ground, like rotting organic matter (garbage, pet waste, a dead animal in walls/attic), or are entering through gaps, often attracted by smells or light. To get rid of them, first identify and eliminate the source (clean drains, take out trash, find hidden carcasses), then block entry points (fix screens, seal cracks), and maintain strict sanitation (clean surfaces, manage waste, remove pet droppings) to prevent recurrence.
Common house flies are attracted to decaying organic filth such as feces and rotting meat, whereas fruit flies seek sugary substances and feed more commonly on overripe fruit, spilled soda, and alcohol.
Flies. Flies are one of the only bugs that are actively affected by colors. While designing more effective fly traps, researchers from the University of Florida found that flies are attracted to blue tones and repelled by warm tones like yellow.
September's daytime temperatures usually sit in the 70s and 80s, with cooler nights in the 50s and 60s. These mild conditions are perfect for flies to reproduce quickly without the stress of extreme heat. Add in the humidity from late-summer thunderstorms, and you have moist environments ideal for fly eggs and larvae.
Citronella Candles
Even so, OLE is regarded as a more effective fly repellent.
