Source Yellow Bug Lights
Insects perceive a small band of the light spectrum, though their band of vision is shifted further to the “right” of the spectrum than ours. In fact, any wavelength higher than about 650 nm is virtually invisible to most flying insects. Click Chart to Zoom In
Low color temperatures are red to yellow. By coloring a bulb yellow, orange or even red, the manufacturer has increased the wavelength into a spectrum unseen by many(most) insects.
Bug lights are not a cure for all your bug problems. This is for a couple reasons. One is that not all insects see the same color spectrum, different bugs see slightly different wavelengths. Second, no light source is made up of one pure wavelength. Even an apparently yellow light may exhibit some shorter (and bluer) wavelengths that insects may still see. No matter what color light bulb you are using, remember. The best thing to do to avoid a swarm of bugs is to turn the light off when you don’t need it.
Hint Mosquito’s Are Not, attracted to a light source. Think about how the mosquito finds someone in total darkness to bite. Regardless of whether they’re human, canine, equine, or avian, what do all living blood sources emit? Carbon dioxide! Mosquitoes, like most biting insects, can home in on the scent of carbon dioxide in the air. Research suggests mosquito’s can detect carbon dioxide from as far as 100 feet away from its source. At the slightest hint of CO2, the mosquito will being flying in zigzags, using trial and error to pinpoint a person to feed on (bite). Carbon dioxide is the most powerful attractant for mosquitoes. Mosquitoes also use other scent clues to find people to bite. Perfume, sweat, and even body odor can attract mosquitoes.
