I’ve always cherished those summer evenings spent on the porch—until the bugs decided to crash the party. For years, I tried everything from sprays to citronella candles and even some bizarre home remedies, but those pesky insects just wouldn’t take a hint and buzz off. That’s when I started researching which light bulbs actually repel bugs or at least don’t attract them as much. After experimenting with different options, myself, I’m excited to share what worked for me and what didn’t. If you’re fed up with your porch turning into a bug convention every night, let’s dive into the best bulbs to keep those critters away from your porch light—and why your current bulb might be the reason they’re sticking around.
Why Porch Lights Attract Bugs in the First Place
Before we jump into solutions, it’s important to understand the issue. Why are bugs so drawn to our porch lights? Well, it turns out that most insects, especially the flying ones like moths and mosquitoes, are attracted to UV light and short-wavelength blue light. Regular incandescent and compact fluorescent bulbs (CFLs) give off a lot of this type of light. This spectrum mimics the moonlight or natural light that insects rely on for navigation, leading them right to your porch.
I used to have standard white LED bulbs, thinking they were energy-efficient and harmless. But I soon realized they were still emitting light in that pesky blue spectrum range. After I switched to bulbs specifically designed to minimize insect attraction, the change was incredible. I could finally enjoy sitting outside without constantly swatting at bugs. So yes, the type of light bulb you choose really does make a difference.
What Makes a Bug-Repellent Bulb Effective?
When I first set out to find better bulbs, I was totally overwhelmed by all the choices. There were yellow lights, “bug lights,” LED options, and amber tints—so many terms to wrap my head around! After testing a bunch of them, here’s what I discovered really makes a difference:
Color temperature: Bulbs with lower color temperatures (typically under 3000K) give off a warm, yellow-orange light that bugs just don’t seem to like.
UV output: The less UV light a bulb puts out, the fewer bugs it attracts.
Brightness: Super bright lights, no matter the color, tend to draw in bugs.
Type of bulb: Incandescents and CFLs tend to attract more bugs than LEDs or specially tinted bulbs.
So, when you’re on the hunt for the best bulbs to keep those pesky bugs away from your porch light, look for something with a soft amber glow, low UV emissions, and moderate brightness. I’ve tried quite a few, and a handful really stood out as the best.
My Favorite Bulbs That Keep Bugs Away (Tested Personally)
Over the past year, I experimented with four different types of bug-repelling bulbs on my front and back porches. Here’s what worked wonders and what didn’t really do much:
1. Yellow “Bug Light” LED Bulbs
I was pleasantly surprised by how effective these were. They give off a warm yellow light that’s easy on the eyes and really keeps insects at bay. After swapping out both porch lights for these, I noticed an 80–90% reduction in bugs compared to regular white LEDs.
Plus, the yellow tint doesn’t look odd at all—it creates a cozy atmosphere, perfect for evening reading or enjoying a cup of tea outside. These bulbs are specifically designed to filter out the blue and UV wavelengths that attract bugs. I personally went with the GE LED Bug Light, but there are plenty of other great options out there.
2. Amber LED Bulbs
These bulbs have a richer orange hue compared to the yellow bug lights. Some folks might find the color a bit dim or strange, but I actually liked it. They were just as effective at keeping insects away and even added a touch of elegance to the porch. The only downside? They’re a tad less bright.
If you’re looking for a way to keep bugs away while still enjoying a cozy atmosphere, amber LEDs are a great choice. I suggest using them in decorative fixtures where a gentle glow is all you need.
3. Warm White LED Bulbs (Under 2700K)
For those who prefer a more traditional white light but still want to minimize bug attraction, warm white LEDs with a low Kelvin rating are the way to go. I tested a 2700K soft white bulb and noticed a significant difference compared to my old 5000K daylight LED.
While these bulbs aren’t as effective as yellow or amber ones, they strike a nice balance if you want that white light vibe without the bug invasion.
4. Incandescent Bug Lights (Don’t Bother)
I gave one a shot out of curiosity, and honestly, it fell short. Sure, it was yellow, but it still put out a fair amount of heat and UV light. Bugs didn’t seem to care that it was labeled a “bug light”—they were still buzzing around. Plus, incandescents consume more energy and have a shorter lifespan.
The takeaway? Just because a bulb is yellow doesn’t guarantee it’ll do the job—what’s inside matters more.
Where and How to Install These Bulbs for Maximum Impact
Once I figured out the right bulbs, I realized that where and how you install them is just as important. Even the best bulb won’t do much good if it’s shining out into the yard or up into the sky. Here’s what worked for me:
I opted for downward-facing fixtures to direct the light toward the ground, keeping it away from where bugs like to hang out.
I kept the brightness low, just enough to illuminate the porch steps and front door.
I paired my amber bulb with a motion sensor, so it only lights up when needed. Less light means fewer bugs.
If your current setup is casting light into open air, think about switching to a covered or hooded fixture. It really makes a difference.

Let’s bust some common myths about bug-repellent bulbs (What Didn’t Work)
I’ve tried a few of those buzzworthy options that just didn’t cut it. Here’s what I wouldn’t recommend, based on my own experience:
Blue or daylight LEDs – Sure, they’re energy-efficient, but their color spectrum is like a magnet for bugs.
CFL bug lights – These still give off some UV light, and honestly, they performed worse than yellow LEDs in my tests.
Coated bulbs – I picked up a “coated white LED” that claimed to repel bugs. It looked white but had a slight tint. Sadly, it still attracted a bunch of bugs. If the light appears white, it’s likely not filtering out enough of the blue spectrum.
Bug zappers near the porch – These didn’t keep bugs away; they just zapped them once they got too close. I still had plenty buzzing around me.
Stick with LED bulbs specifically designed to repel bugs, especially those labeled warm white, amber, or yellow.
Bonus: Pair the Right Bulbs with These Extra Tips
Choosing the right bulb is a fantastic start, but I noticed even better results when I added a few more bug-busting strategies:
Turn off porch lights when you’re not using them. Less light = fewer bugs.
Keep your porch tidy. Crumbs, food, or even plant sap can lure insects in.
Use natural deterrents like citronella plants or essential oil sprays around the edges of your porch.
Seal up any cracks and gaps near doors and windows to stop bugs from sneaking inside.
