Flies and mosquitoes, on the other hand, are attracted to blue tones and repelled by warm tones like yellow and orange. They prefer dark colors because they use their heat receptors to locate warm bodies to feed on.
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.
Wear the Right Stuff
Black flies are often attracted to dark clothing, much like the shade or darker areas. To ward these pests away, try wearing bright colors or white clothes when you head out. Not only will this help deter them, but it will also make them easier to spot should they land on you.
... the free choice experiment, the highest numbers of resting flies were found on dark blue and white, both were statistically at par, followed by sky blue and red, while yellow and black were least preferred colors.
Bright white or bluish lights (mercury vapor, white incandescent and white florescent) are the most attractive to insects. Yellowish, pinkish, or orange (sodium vapor, halogen, dichroic yellow) are the least attractive to most insects.
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. More studies confirmed the correlation between blue lights and fly attraction.
LEDs on the other hand—both “cool‐white” and “warm‐white”—were the least attractive to insects. Yellow-hued light bulbs are worth trying, too. “Yellow lights—and red lights—do not attract insects as much as regular white lights,” Russell says.
Flies cannot fly off at an angle and have to fly straight upwards before being able to head off in another direction. This leaves them vulnerable for the first few inches of their flight and easier to trap. Another weakness is the fly's inability to respond when confronted with two threats at the same time.
Are houseflies attracted to blue light? Yes, houseflies are attracted to blue light. The intense beams of UV-A from LED lights emitting from Rentokil Lumnia Fly Control attract pests particularly the houseflies as their eyes are sensitive to light of a specific wavelength.
Most flies, with the notable exception of mosquitoes, are daytime fliers. They require polarized light to guide them visually. They remain active during the day and become inactive during the night.
Eucalyptus oil is a good option, but you can also use lavender, citrus, pine, clove, peppermint, and thyme essential oils. Most flies hate these scents, so the oils will act as a fly repellent.
Apple cider vinegar is an old-timey remedy that many say helps with mosquitoes, black flies, and ticks. Start three to four days before your planned outdoor activity and take a tablespoon of vinegar three to four times a day to help your skin ward off biting bugs on its own.
Lavender, eucalyptus, peppermint and lemongrass essential oils – Not only will spraying these oils around the house create a beautiful aroma, but they will also deter those pesky flies too. Apple cider vinegar – Flies love the smell of apples and vinegar.
Afraid of shadows
The flies looked startled and, if flying, increased their speed. Occasionally the flies froze in place, a defensive behaviour also observed in the fear responses of rodents. The shadows even caused hungry flies to leave a food source, when that was presented during another phase of the experiment.
A key to making the device effective was the discovery that flies are three times more attracted to the color blue than to yellow and that yellow actually seemed to repel flies.
There are many smells that flies hate, and we will be describing the benefits of the most notable scents that repel flies. These include peppermint, basil, pine, rosemary, rue, lavender, eucalyptus, and bay leaves.
Turn Off Lights
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. Reduce the number of bright lights on inside your house at night as well.
Outdoor Lighting Options That Won't Attract Bugs
The outdoor lighting options, which will not attract bugs are the LED, compact fluorescent, sodium vapor, and the halogen bulbs.
It seems this light source is also attractive to insects, too. Rentokil's global study of insect attraction to light found LED technology, when combined with an insect light trap, was a superior attractant in killing and capturing flies than traditional light sources.
Slap the fly with one hand.
Swat a fly by trapping it between one hand and a hard, flat surface that you have gotten it to land on. Move slowly toward the fly, then slap it quickly and firmly with your hand. Approach the fly very slowly until you are within an arm's length of it.
Generally speaking, flies represent something that is annoying or bothersome. They might represent a problem that you are trying to ignore or something that is causing you stress. Alternatively, flies might symbolize something that is rotting or decaying. This could be a situation in which you feel trapped or stagnant.
Yellow and amber LED lights will attract the fewest number of insects and bugs. White and blue LED lights attract the most amount of bugs, with ultraviolet and green LED lights also attracting bugs. Red LED lights are the least appealing to bugs—but unfortunately can be less useful for human use.
Bugs are naturally attracted to bright colors like white, yellow or orange. Colors like green and blue won't register as vividly when seen in the UV spectrum, deterring bugs away from these colored objects.
Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. Lights that emit a majority of longer wavelengths (yellow/orange/red colors) are less visible. Heat can also draw bugs into an area.
