Whether it’s a campfire or a JumboTron, light sources attract insects. Traditional incandescent bulbs emit light in the color spectrum that’s particularly attractive to bugs. Bulbs that produce a yellow or orange-colored hue are less attractive to insects and it’s the primary reason that yellow “bug lights” were created.

Navigational Aid

The question of why insects are drawn to light sources is multi-faceted. Bugs use light to navigate their surroundings whether they’re apparent during the day or only come out at night. Nocturnal insects use any available light source as a navigational beacon. The larger the illumination source, the more forcefully they’re drawn to it.

Insects that are attracted to light are known as positively phototactic, a term used to describe bugs that are drawn to light. Insects navigate by keeping the moon or sun on a constant angle in relation to themselves. When confronted with the bright lights used by humans that emit in all directions, it confuses them and interferes with their inborn navigational abilities.

Food and Mates

Additionally, many insects utilize certain types of plants, along with evening-blooming flowers, as part of mating rituals and a food source. Many of those plants reflect a small amount of UV rays and traditional lights also emit small amounts of ultraviolet light, which further leads to the attraction.

Bright Solutions

Any light source will attract bugs, but switching to LED lights is one remedy that’s been successfully utilized in-home lighting arrangements. LEDs emit light in the yellow/orange spectrum that’s less attractive to the unwanted pests. The light difference is generally invisible to the average eye, since humans aren’t equipped to see in the same wavelengths and frequencies.

The downside to traditional bug lights is that they tend to attract insects that are larger. LEDs with a yellow hue are far better at not attracting insects than any other, though if individuals haven’t switched to a more energy-efficient LED, a yellow bug light is the second-best option. The yellow color in LEDs isn’t noticeable to humans, but makes a difference to bugs.

LED lights are eco-friendly, less expensive to operate, and emit illumination in the spectrum that’s least attractive to insects. That means fewer bugs at any gathering and more enjoyment for everyone involved.
