The Bark Centipede is a fast-moving predatory arthropod commonly found beneath loose tree bark, logs, stones, and other moist woodland debris. Often referred to as the Eastern Bark Centipede, this species belongs to the centipede class Chilopoda. Although it may occasionally wander indoors, it is primarily an outdoor species that plays an important ecological role as a predator of other small insects and arthropods.
Identification
Bark centipedes have elongated, flattened bodies with numerous body segments. Each segment contains one pair of legs, giving the animal its characteristic multi-legged appearance. Their coloration is usually reddish brown, dark brown, or yellowish. Most bark centipedes range from 1–3 inches long depending on species and age.
Distribution and Habitat
Bark centipedes are widely distributed across North America and are commonly found in forests, gardens, wooded yards, and landscapes with abundant organic debris. They thrive in moist environments beneath bark, stones, mulch, and leaf litter where prey insects are abundant.
Life Cycle and Behavior
Like other centipedes, bark centipedes are nocturnal predators. They hunt insects, spiders, larvae, and other small invertebrates. Females lay eggs in soil or protected crevices where the young develop into small versions of the adults.
Pest Status
Bark centipedes are not structural pests and do not damage buildings or stored products. However, they may occasionally wander indoors in search of moisture or prey. Their presence indoors usually points to excess humidity, hidden insect activity, or nearby organic debris that provides shelter.
Prevention
- Reduce excess moisture around foundations.
- Remove bark, mulch piles, and wood debris near the home.
- Seal cracks and gaps around doors and windows.
- Maintain dry crawlspaces and basements.
- Trim vegetation away from the structure.
Control
Indoor bark centipedes can usually be removed manually or with a vacuum. Preventive measures such as moisture control, sealing entry points, and debris removal are usually sufficient to prevent recurring issues. Chemical treatment is rarely necessary unless centipedes are appearing in large numbers alongside other moisture-loving pests.
