Not every creepy-looking creature around your home is a threat. Some are simply misunderstood. The bark centipede is a perfect example. With its flattened body, quick movements, and many legs, it can easily make homeowners uncomfortable. But behind that intimidating appearance is a small predator that usually spends its time hunting other insects outdoors. The real concern begins when you start seeing them near your home. A bark centipede does not appear without a reason. It may be responding to moisture, shelter, or an increase in insect activity around your property. Understanding these signs can help you solve the problem instead of only removing the insect you see.
In this guide, we will explore bark centipede identification, their habits, potential risks, and practical steps for effective control.
What Is a Bark Centipede?

A bark centipede is a predatory centipede that usually lives outdoors. It gets its name because it often hides beneath tree bark, fallen logs, rocks, and other natural materials.
The term bark centipede does not always describe one exact insect. Several bark centipede species can be grouped under this common name. Some species belong to groups such as Cryptopidae. Others include larger centipedes commonly found around wooded areas.
You may also hear the name eastern bark centipede when discussing certain outdoor centipedes.
Although species can vary, most bark centipedes share similar characteristics.
They usually have:
- A long, flattened body
- Multiple body segments
- One pair of legs per segment
- Fast movement
- A preference for dark and damp areas
Their natural centipede habitat includes:
- Tree bark
- Leaf litter
- Gardens
- Wood piles
- Rocks
- Damp soil
- Mulched areas
Unlike termites, bark centipedes do not eat wood. They are hunters.
Their main purpose is finding small insects and other creatures to feed on.
How to Identify a Bark Centipede

Identifying a bark centipede is easier when you know what features matter.
You do not need to catch one. You can usually identify it through appearance and behavior.
Look at the Body Shape
The first thing to notice is the body.
Bark centipedes have a flattened appearance. This helps them move under bark and through narrow spaces. Their body is divided into many segments. Each segment helps support their movement and flexibility. A bark centipede usually looks more armored than many common household insects.
This body shape helps separate them from millipedes.
Millipedes usually have:
- Rounder bodies
- Slower movement
- Two pairs of legs on most segments
Centipedes have:
- Flat bodies
- Faster movement
- One pair of legs per segment
Check the Legs
The legs are one of the easiest identification clues.
Centipedes are famous for their many legs. However, counting every leg is unnecessary.
Instead, look for:
- Legs extending from both sides
- Quick running movement
- A long body with many segments
Different species have different numbers of legs.
For example, some bark centipedes may have 21 pairs of legs, while others have more.
The exact count helps experts identify species. Homeowners usually only need the basic differences.
Look at the Color

Bark centipedes often have natural earth-tone colors.
Common colors include:
- Reddish brown
- Orange brown
- Dark brown
- Chestnut shades
The eastern bark centipede and similar species may have darker bodies with lighter legs.
However, color should not be your only clue.
Lighting, age, and species differences can change their appearance.
Understand Bark Centipede Size
Many people ask about bark centipede size because these insects can appear larger than expected.
The average size range is usually between one and three inches.
Some related species may grow larger.
A simple size comparison:
- Young centipedes may look very small.
- Adult bark centipedes are easier to notice.
- Larger species may appear more alarming.
A bark centipede baby is usually smaller and lighter in color.
Like other centipedes, they grow through several stages. This process is part of the bark centipede life cycle.
Watch How It Moves
Movement is another strong clue.
Bark centipedes are hunters.
They usually:
- Hide during the day
- Become active at night
- Run quickly when disturbed
- Search for insects
A fast-moving insect disappearing under a rock or piece of wood matches typical centipede behavior.
Bark Centipede Diet: What Do They Eat?

Understanding the bark centipede diet helps explain why they appear around homes.
Bark centipedes are predators.
Their diet mainly includes:
- Small insects
- Spiders
- Larvae
- Other small arthropods
The general centipede diet depends on the species and environment.
However, most centipedes hunt live prey. This is why seeing bark centipedes may sometimes indicate another pest problem nearby. If your yard has many insects, centipedes may follow. They are not attracted to your furniture, food, or wooden structures. They are attracted to their next meal.
