Quick answer
Why does my porch light attract bugs? Many insects are drawn to blue and ultraviolet light, and bright white bulbs give off a lot of both. Turn the light off when you do not need it and clear the webs. For the nights you do need it, a yellow bug light bulb gives off far less of the light bugs follow, so fewer gather at your door.
Free fix vs. permanent fix
Turn it off, hide the glow, clear the webs
- Switch the porch light off when you do not need it
- Close blinds so indoor light does not spill onto the porch
- Knock down webs and egg sacs around the fixture
- Use a motion sensor or timer so the light is on less
How long it lasts: Works whenever the light is off. When you need light at the door, a bright white bulb still draws bugs in.
A yellow bug light bulb
Insects are most drawn to blue and UV light, which cool-white bulbs give off in quantity. Yellow or amber bulbs give off very little of it. You keep a light at the door and lose most of the swarm.
What to get: Yellow bug light bulb
How long it lasts: As long as the bulb lasts. LED bulbs often run for years.

Why it happens
Blue and UV light
Insects see short wavelengths strongly. Cool-white and daylight bulbs give off the most blue, so they pull in the most moths, beetles and midges.
Brightness
A very bright bulb can draw insects from farther away. Light colored walls and a bare bulb throw the glow even wider.
A light left on all night
A porch light that burns from dusk to dawn gives bugs hours to find it. They gather, mate and die there, and you sweep them up in the morning.
Spiders that follow the bugs
Webs around a porch light are a sign that bugs are already feeding spiders there. Remove them or the spiders will stay.

-
Turn the porch light off when you do not need it
A light that is off attracts nothing. Switch it off at bedtime, and when you are out for the evening, unless you need it for safety.
-
Close blinds and curtains
Light leaking from nearby windows spills onto the porch and draws bugs from a wide area. Close blinds on the windows that face the porch at night.
-
Knock down webs and egg sacs
Tool used: Broom or dusterUse a broom or duster around the fixture and the porch ceiling. Do this in the morning, when the bugs are not around.
-
Swap in a yellow bug light bulb
Tool used: Yellow bug light bulbSwitch the light off at the wall, set up the step stool and let the old bulb cool. Match the base size, usually E26, and stay below the maximum wattage printed on the fixture. Use a bulb rated for damp or wet locations if the fixture is open.

When free fixes aren't enough
If you need a light at the door every night, you cannot turn it off, and a white bulb will keep drawing moths and beetles. A yellow bug light bulb will not make bugs vanish, because they still bump into any lit fixture. But owners report far fewer gathering there. The light looks amber, which some people dislike, and a warm white LED at about 2700K or lower is a middle ground. If the fixture flickers, buzzes or feels very hot, turn it off and call an electrician.

Yellow bug light bulb
Fixes: swarms of moths and beetles drawn to bright white bulbs
Look for: Labeled as a bug light, or a yellow or amber tint; Rated for outdoor, damp or wet locations if your fixture is open; The right base size, usually E26, and under your fixture's wattage limit; Dims or runs cool enough for an enclosed fixture.
- Who it's for
- Anyone who needs porch light most nights and is tired of insects at the door.
- Honest downside
- Your main problem is mosquitoes. They find people by breath and body heat, not light, so a bulb will not help.
Outdoor motion sensor light socket
Fixes: bugs that gather because the light burns all night
Look for: Weather rated for outdoor use; An adjustable sensitivity and a timer; Works with your bulb type, including LED; A tight fit in your socket.
- Who it's for
- Doorways where you only need light when someone walks up.
- Honest downside
- You want the light on all night for security. Or your fixture is too small for the adapter.

Porch light that keeps bugs away: what to look for
- Color: yellow, amber or warm white, not cool white.
- Brightness: only as many lumens as you need to see the door.
- Control: a motion sensor, timer or dusk-to-dawn sensor that keeps it off when no one is there.
- Shielding: a fixture that points the light down, not out into the yard.
Safe bulb swap checklist
Switch the light off at the wall, and at the breaker if the fixture is old or the wiring looks worn. Let the old bulb cool before touching it. Check the label for the base size and the wattage limit. Do not use the fixture if you see cracked sockets, scorched plastic or exposed wires. Call an electrician instead.
What to skip
Bug zappers and sprays by the door
A zapper near the porch pulls more insects toward your house, and studies find that they kill few biting bugs. Spraying insecticide around the fixture also adds a chore without fixing why the bugs are there. Change the bulb and the habit instead.
