If you’ve ever spent a warm evening outside under your porch lights, string lights, or any other lighting, chances are you’ve shared that space with swarms of bugs. Insects such as mosquitoes, moths, and gnats are notoriously attracted to artificial light, especially the bright white variety. But there’s a simple, science-backed solution for keeping these…
Why Are Bugs Drawn to Light Bulbs?
Most flying insects rely on ultraviolet (UV) light and short wavelengths of visible light, such as blue and white, for navigation. Traditional white incandescent, halogen, and many cool white LED bulbs emit a spectrum that includes these blue tones and often some UV, essentially acting as a beacon for bugs.
Yellow light, on the other hand, contains longer wavelengths that are much less attractive to insects. By replacing standard white bulbs with yellow ones, you can significantly reduce the number of pests buzzing around your patio or front door. These bulbs don’t repel insects; they simply don’t attract them.
Swap Out White Bulbs for Yellow Ones
Swapping bulbs is easy and affordable. Yellow bulbs are widely available at hardware stores, home improvement stores, and online, typically costing just a few dollars more than traditional bulbs. They’re available in incandescent, CFL, and LED versions, with LEDs being the most energy-efficient and long-lasting option.

While no light is completely bug-proof, yellow bulbs can make a noticeable difference, especially when used alongside other pest control strategies such as spatial mosquito repellents, portable fans, and eliminating standing water where mosquitoes breed.
This small lighting change is also environmentally friendly. Using yellow or warm-hued lights can help reduce light pollution, which negatively impacts nocturnal animals and disrupts ecosystems. You might even notice fewer nighttime visits from unwanted wildlife that are drawn by insect activity near bright lights.
Whether you’re hosting a backyard barbecue or simply enjoying a quiet evening under the stars, swapping your white outdoor bulbs for yellow ones can help create a more peaceful, pest-free environment. It’s a quick fix that pays off all season long.
