Orbs: Ghosts, Dust, or Bugs?
Lesson 1: Debunking Orbs
One of the most common claims in the paranormal field is the appearance of "orbs" on security cameras, photographs, and investigation footage. Many people believe they have captured a spirit when they see a glowing ball of light floating across their screen. In reality, most orb sightings can be explained by natural causes such as insects, dust, moisture, or airborne debris.
While I do believe that true paranormal phenomena can occur, genuine orb activity is extremely rare. In over two decades of investigating claims of paranormal activity, the vast majority of orb reports have turned out to be something completely explainable.
The Night Vision Test
One of the first signs that you are probably not looking at a paranormal orb is if the camera is operating in night vision mode.
Most security cameras use infrared (IR) light to see in the dark. Insects, dust particles, rain, pollen, and other airborne objects reflect that infrared light back into the camera lens. This reflection creates bright balls, streaks, or glowing objects that people often mistake for spirits.
Think about it this way:
A true orb is often described as a ball of light or energy. Light itself does not reflect light in the way a physical object does. However, a bug, dust particle, or water droplet will reflect infrared light because it is a physical object.
If your camera is in night vision mode and you see a glowing object moving across the screen, your first question should be:
"What physical object is reflecting the infrared light?"
not
"Did I just capture a ghost?"
Dust vs. Orbs
Dust is one of the most common causes of false orb sightings.
Dust particles are constantly moving through the air both inside and outside a building. Air conditioning systems, heaters, ceiling fans, open doors, wind, and normal foot traffic can all stir up dust.
Because dust is lightweight, it often:
Falls slowly downward
Drifts side to side
Changes direction with air currents
Appears suddenly as it passes close to the lens
When illuminated by infrared light, dust can appear as a glowing orb even though it is simply a particle floating through the air.
Insects and False Paranormal Activity
Insects are another major source of orb reports.
Many bugs are attracted to the warmth and infrared lights surrounding security cameras. As they crawl across the lens or fly near the camera, they can create strange shapes that resemble spirits, shadow figures, or glowing orbs.
A bug can:
Reflect infrared light
Appear larger than it really is
Create a transparent or ghostly appearance
Cast unusual shadows
Seem to appear or disappear instantly
When an insect crawls directly across the lens, it can create what looks like a shadow figure moving through a room. When it flies away, it may appear to vanish without explanation.
In reality, it simply moved out of the camera's field of view.
Looking at the Whole Event
One mistake many investigators make is focusing only on the orb itself.
Instead, ask:
What happened before the sighting?
What happened after the sighting?
If a glowing object appears on camera and absolutely nothing unusual follows, there is a good chance you are looking at a natural occurrence.
If an orb truly represented some form of human energy or intelligent presence, you would expect some type of interaction, response, or related activity. For example:
An unexplained knock
A voice
An object moving
Multiple witnesses experiencing the same event
Repeated activity occurring in the same location
Context matters.
An unexplained event supported by additional evidence deserves further investigation. A single glowing object floating across a camera usually does not.
The Energy Question
Many people claim that orbs are human spirits attempting to manifest.
If that is true, then we must ask a logical question:
Why would a spirit expend the energy required to become visible only to drift across a camera and accomplish nothing else?
If a spirit is intelligent and capable of manifesting, we would expect some purpose behind the action. Random floating balls of light with no interaction, communication, or associated activity are far more likely to have a natural explanation.
Key Takeaway
Before calling something paranormal, always rule out the ordinary.
Ask yourself:
Was the camera using infrared night vision?
Could dust be present?
Could an insect have crossed the lens?
Was there rain, pollen, humidity, or debris in the air?
Did anything unusual happen before or after the sighting?
Remember:
Most orbs are dust, insects, moisture, or other environmental factors.
A true paranormal event should involve more than a glowing ball of light. It should present evidence that cannot be easily explained and should be evaluated within the context of the entire event—not just a single frame of video.
Evidence & References
The purpose of this lesson is not to dismiss every unusual experience. It is to show why investigators should rule out ordinary causes before calling something paranormal. The following sources help explain why dust, insects, moisture, and infrared light are commonly mistaken for orbs.
Backscatter Photography
Why it matters: Backscatter is a known camera effect where light reflects off small particles near the lens, creating orb-like images.
JAKS Take: This is one of the most important explanations to understand before reviewing orb photos or night vision footage.

Orbs on Security Cameras
Why it matters: Security cameras often use infrared night vision, which can make dust, bugs, spider webs, rain, pollen, and moisture appear bright or glowing.
JAKS Take: If the camera is in night vision mode, always look for a physical object reflecting IR light before assuming paranormal activity.

Paranormal Investigator Perspective
Why it matters: Many experienced paranormal investigators agree that most orbs are caused by dust, insects, pollen, moisture, or camera reflection.
JAKS Take: An orb by itself is rarely strong evidence. Look for supporting activity, patterns, witnesses, or additional unexplained events.

Final Investigator Note
A single glowing object on camera should never be the entire case. Before calling it paranormal, ask what else happened before, during, and after the sighting. If nothing occurred except a floating light on night vision, the most likely explanation is dust, a bug, moisture, or another natural cause.
Before you call it paranormal, rule out the ordinary.
