4 Reasons Why You Have a Centipede Infestation

House centipedes are drawn to homes for various reasons. So, understand these factors to learn how to prevent and tackle infestations effectively.

1. Moisture, Food, and Other Infestations

Homes with moist areas provide ideal conditions for centipedes and millipedes. Specifically, these indoor conditions attract them:

Indoor Conditions

Attraction for Centipedes

High Moisture

Damp areas, such as crawl spaces, sustain their hydration

Food Sources

Prey availability like smaller insects (termites, bed bugs)


Other household pest infestations (cockroaches, silverfish) signal a stable food source

2. Easy Entry Points

A home with unsealed entry points can inadvertently invite centipedes indoors. So, take note of the typical entry points for these arthropods:

  • Crevices and Cracks: Openings in foundation walls and around windows.
  • Unsealed Gaps: Spaces under doors or around pipes entering the house.
  • Floor Drains: Often overlooked, these can grant access from subterranean levels.
  • Poorly Fitted Baseboards: Offer direct entry from wall voids and adjacent rooms.

3. Lack of Natural Predators

Centipedes thrive in homes lacking their natural enemies since these predators are crucial in controlling their populations.

While you can’t invite them inside the home, having them at a safe distance outdoors can deter these creepy crawlies. Here’s how you might encourage them:

Natural Predators

Encouragement Tips


Allow harmless spiders to reside in less-frequented corners


Place bird feeders to attract insect-eating birds


Maintain a garden pond to support a healthy frog population

4. Other Potential Factors (Less Common)

There are also rare causes for a house centipede infestation. A couple of these factors include:

  • Transportation in Containers: Centipedes hiding in cardboard boxes and indoor plants might be brought inside.
  • Indoor Breeding: Rarely, species of centipedes might establish a breeding area in secluded parts of the home, such as rarely disturbed closets or attics.
