What Are Thunder Flies and Why Are They in Your Monitor?
Thunder flies, also known as thrips, are minuscule insects attracted to light and heat. These pests are just about 1mm long and can easily sneak into tight spaces—including your computer monitor. If you’ve spotted small, moving black or brown lines inside your screen, chances are you’re looking at thunder flies in monitor screen.
These insects typically swarm during warm, humid weather and are naturally drawn to bright areas. Your monitor’s heat and backlight make it an irresistible trap. They can enter through tiny ventilation holes or gaps in the casing, which are impossible to see with the naked eye.
Common signs you have thunder flies inside your monitor: thunder flies in monitor
- Tiny black/brown specks that move slowly
- Appearing mainly when the screen is bright or white
- No physical damage but annoying visual disturbance
Can Thunder Flies Damage Your Monitor?
Technically, thunder flies don’t physically damage your monitor’s hardware. They don’t chew through wires or disrupt circuits. However, they can:
- Leave behind smudges or waste that may appear as permanent screen blemishes
- Die inside the panel, leaving visible marks
- Reduce user experience due to the distraction of moving specks
While the insects themselves are harmless in terms of electronics, their presence can make your monitor look faulty and unclean. This can be especially frustrating for designers, gamers, or professionals who rely on pristine display quality. thunder flies in monitor
How Do Thunder Flies Get Inside a Monitor?
Thunder flies are incredibly small and flexible, which allows them to crawl through:
- Air vents designed for cooling
- Gaps between the monitor bezel and screen
- Spaces in poorly sealed panels
Your monitor’s backlight emits both heat and light—two things that attract these insects. Once inside, they may not be able to find their way out, resulting in either dead spots or sluggish movement visible on the screen.
Safe Ways to Remove Thunder Flies from a Monitor
Removing thunder flies without damaging your monitor can be tricky but possible. Here are a few safe methods: thunder flies in monitor
1. Turn Off the Monitor and Use a Light Source
Try placing a flashlight or bright lamp next to the screen’s vent while the monitor is off. The insects may be lured out by the stronger external light source.
2. Gently Tap the Monitor Frame
Tapping lightly around the monitor frame (not the screen) may encourage the insects to move away from the visible area. Do not press the screen directly.
3. Use Compressed Air
Blow air into the monitor’s ventilation slots to dislodge any stuck insects. Use short bursts and do not hold the can upside down.
4. Let Gravity Work
Tilt or rotate your monitor to encourage the insects to crawl toward an exit. This works best when combined with a light source outside the screen.
Avoid opening the monitor yourself unless you’re trained. It may void the warranty or cause internal damage.
