What Color Light Keeps Bugs Away: Facts and Tips

Are you tired of bugs invading your evening outdoor gatherings? Fact is, these insects are particularly attracted to certain colors and spectrums of light. This blog post is here to guide you in choosing the right light color to keep those pesky bugs at bay.

Let’s illuminate this topic together!

Key Takeaways

  • Bugs are attracted to LED lights with ultraviolet and blue wavelengths, while yellow and red lights are less appealing to them.
  • Yellow LED lights are effective at repelling bugs and even outperform conventional “bug lights.
  • Other bug-repelling options include yellow compact fluorescent bulbs, red lights, insect-repellent bulbs, bug-repelling light fixtures, and outdoor lighting designed for insect control.
  • Using warm – colored LED lights that emit yellow, orange, or red colors can help keep bugs away.

What Light Attracts Insects?

LED lights, particularly those with ultraviolet (UV) and bluish wavelengths, are known to attract flying insects.

Characteristics of LED light

LED lights are special. They give off light in a color we call “wavelength”. Some wavelengths attract bugs, others do not. Bugs love ultraviolet light and blue colors. But, LED lights can also put out yellow or red wavelengths.

These colors don’t attract bugs as much. So, by using the right kind of LED light, you can keep many pests away from your home or yard!

Why are bugs attracted to light?

Bugs are attracted to light because they often mistake it for the moon or the sun. They use these natural sources of light to navigate their surroundings. However, artificial lights can confuse them and cause them to fly towards it instead.

Bugs are particularly drawn to ultraviolet and blue lights, so they tend to swarm around those types of bulbs. The color and intensity of the light also play a role in attracting bugs.

So, be mindful of the type of light you use if you want to keep bugs away.

Do LED Lights Keep Bugs Away?

LED lights come in different colors, but does the color of the light actually repel bugs?

The effectiveness of different light colors

Different colors of light have varying effectiveness when it comes to repelling bugs. Here is a breakdown:

Color of Light Effectiveness at Repelling Bugs
Blue Blue light bulbs are more likely to attract bugs, making them the least effective at repelling insects.
Yellow Yellow light, particularly from LED sources, is less attractive to bugs, hence more effective in repelling them. Yellow-hued LEDs even outperform conventional “bug lights”.
Red Red-colored light is known to keep bugs away. It is thus a good option for those looking to deter insects.
White White LED lights, which emit a broad spectrum of colors, may attract fewer bugs than blue lights, but aren’t as effective as yellow or red lights.

By choosing the right color of light, you can significantly reduce the number of bugs attracted to your outdoor areas. For instance, opting for a yellow bug light can help you avoid attracting bugs. It’s also important to remember that not all bugs are attracted to the same spectrum of light, hence a mix might be beneficial based on the specific pests in your area.

Yellow LED lights and bug repellent

Yellow LED lights can be an effective bug repellent. Bugs are less attracted to yellow light compared to other colors, especially blue light. Yellow-hued LEDs emit wavelengths that bugs find unappealing, making them a good choice for keeping bugs away from outdoor areas.

In fact, research has shown that yellow LEDs are even better at repelling bugs than special “bug lights” designed to avoid attracting insects. So if you want to enjoy your DIY projects without the annoyance of bugs buzzing around, consider using yellow LED lights as a natural and efficient bug repellent.

Other bug-free outdoor lights

Other bug-free outdoor lights include:

  • Yellow compact fluorescent light (CFL) bulbs: These emit a yellow light that is less attractive to bugs.
  • Red lights: Bugs are less likely to be attracted to the red end of the color spectrum.
  • Insect-repellent light bulbs: These bulbs are specifically designed to deter insects from gathering around outdoor areas.
  • Bug-repelling light fixtures: Certain light fixtures are designed with bug repellent properties, making them a good option for keeping bugs away.
  • Outdoor lighting for insect control: Some outdoor lighting options are specifically designed to minimize bug attraction and reduce the presence of bugs in your outdoor spaces.

The Best Light Bulbs to Use

Choose light bulbs that don’t attract bugs, such as yellow compact fluorescent (CFL) bulbs or bug-repellent light fixtures.

Types of bulbs that don’t attract bugs

The benefits of warm-colored LED lights

Warm-colored LED lights, such as those that emit yellow, orange, or red colors, have several benefits when it comes to keeping bugs away. These warm hues are less likely to attract insects compared to blue light bulbs or brighter white lights.

LED lights with yellow wavelengths were found to be even better at repelling bugs than special “bug lights” marketed for this purpose. So if you’re looking for bug-free lighting options for your outdoor spaces, choosing warm-colored LED lights can help prevent those pesky insects from buzzing around.

Natural Repellents for Bugs

Use natural methods to keep bugs away, such as planting bug-repelling plants, like lavender or citronella, using essential oils like lemon eucalyptus or peppermint, and keeping outdoor areas clean and free of standing water.

Other natural methods to keep bugs away

Here are some natural ways to keep bugs away:

  1. Keep your outdoor area clean and free of standing water, as mosquitoes breed in stagnant water.
  2. Use citronella candles or torches, which can help repel mosquitoes and other flying insects.
  3. Plant mosquito – repellent herbs like lavender, mint, and basil around your outdoor space.
  4. Install bug screens on doors and windows to prevent insects from entering your home.
  5. Avoid wearing dark-colored clothing and strong-scented perfumes or lotions, as these can attract bugs.
  6. Use fans outdoors to create a breeze that makes it harder for bugs to fly near you.
  7. Remove any rotting fruit or food scraps, as these can attract fruit flies and other pests.
  8. Consider using essential oils like lemon eucalyptus or peppermint as natural bug repellents.

The importance of outdoor lighting placement

Proper placement of outdoor lighting is crucial in deterring bugs and creating bug-free areas. Bugs are attracted to light, so it’s essential to position your lights strategically.

Avoid placing bright white or bluish lights near entryways or seating areas where people gather, as these colors tend to attract insects. Instead, opt for yellow-hued LED lights, which emit wavelengths that bugs find less appealing.

By placing bug-repellent light fixtures away from high-traffic areas and directing the light downwards rather than upwards, you can minimize bug attractions and create a more enjoyable outdoor space without pesky intruders.


In conclusion, the color of light can play a role in keeping bugs away. LED lights with yellow hues are less attractive to insects compared to blue or white lights. Bulbs that emit yellow, orange, or red colors are also effective at repelling bugs.

By choosing the right type of light bulb and avoiding ultraviolet and blue light, you can create bug-free outdoor spaces.


1. What color light keeps bugs away?

Bugs stay away from yellow compact fluorescent lights (CFL) and some LED lights. Ultraviolet UV, bright white, and mercury vapor lights attract them.

2. How does the color of a light bulb help with bug avoidance?

The science of light and insect behavior shows that insects are less attracted to yellow CFL bulbs.

3. What are good lighting choices for bug prevention?

Choosing the right light bulb like a yellow CFL or specific LED can help make your outdoor spaces bug-free.

4. Does using an insect repellent light bulb work in mosquito control?

Yes, some insect-repellent light bulbs and fixtures can be used as natural pest control to manage mosquitoes.

5.What is the part played by greenlight in attracting insects ?

Greenlights don’t attract many insects as much as other types such as bright white or UV lights.
