Identifying the causes will help you with controlling centipedes, addressing issues like moisture and food sources, and implementing effective prevention strategies, creating a pest-free home. We cover everything from preventing pests to employing DIY solutions.
1. Understanding Centipedes and Their Behavior
Centipedes are elongated, multi-legged arthropods belonging to the class Chilopoda. Their name literally means “hundred feet,” although the actual number of legs varies, ranging from 15 to over 170 pairs, depending on the species. Each body segment has one pair of legs, setting them apart from millipedes, which have two pairs of legs per segment. Centipedes are predators, feeding on insects, spiders, and other small invertebrates. They are nocturnal creatures, preferring to hunt in the dark and hide in damp, dark places during the day. Their natural habitats include soil, leaf litter, under rocks, and logs.
1.1. Identifying Common Types of Centipedes Found in Homes
Several species of centipedes may find their way into homes, but the most common one is the house centipede (Scutigera coleoptrata). This species is easily identified by its long, slender body, up to 15 pairs of long legs, and distinctive stripes. House centipedes are typically yellowish-brown with dark stripes running along their body. They are fast-moving and can often be seen darting across walls and floors. Other types of centipedes that might be found indoors include the garden centipede (Lithobius forficatus) and the stone centipede (various species in the genus Lithobius). These are generally smaller and darker in color than house centipedes.
1.2. Centipede Habitat and Diet: What Attracts Them to Your Home?
Centipedes are attracted to homes that offer them food, moisture, and shelter. Their diet consists primarily of insects, spiders, and other small arthropods. If your home has an abundance of these pests, centipedes will be drawn in to feed on them. Moisture is another key factor. Centipedes thrive in damp environments, so areas with high humidity or water leaks are particularly attractive. Common entry points for centipedes include cracks in the foundation, gaps around pipes, and poorly sealed windows and doors. Once inside, they often hide in basements, bathrooms, and other damp areas.
2. Common Reasons Why Centipedes Invade Your House
Understanding why centipedes are entering your home is the first step in preventing future infestations. Several factors can contribute to their presence, including environmental conditions, structural issues, and the availability of food sources.
2.1. Moisture and Humidity
Centipedes need moisture to survive and are drawn to damp environments. Leaky pipes, poor drainage, and high humidity levels can create ideal conditions for them.
2.2. Abundance of Food Sources
Centipedes feed on other insects and arthropods. If your home has a population of these pests, centipedes will be attracted to the readily available food source.
2.3. Entry Points and Shelter
Cracks in the foundation, gaps around windows and doors, and other structural issues can provide easy access for centipedes to enter your home. They also seek shelter in dark, undisturbed areas.
2.4. Seasonal Changes and Weather Conditions
Changes in weather, such as heavy rain or extreme temperatures, can drive centipedes indoors in search of more stable and favorable conditions.
3. Identifying Potential Entry Points
To effectively prevent centipedes from entering your home, it’s important to identify and seal potential entry points. A thorough inspection of your home’s exterior and interior can help you locate these access areas.
3.1. Cracks and Gaps in Foundation
Check the foundation for any cracks or gaps, especially near ground level. These are common entry points for various pests, including centipedes.
3.2. Openings Around Pipes and Utility Lines

6. Understanding the Life Cycle of Centipedes
Understanding the life cycle of centipedes can provide valuable insights into their behavior and help you to develop more effective control strategies.
6.1. Egg Laying and Hatching
Female centipedes lay their eggs in damp soil or under rocks and logs. The eggs are typically laid in clusters and covered with a sticky substance to protect them from drying out. The incubation period varies depending on the species and environmental conditions, but it generally takes several weeks for the eggs to hatch.
6.2. Nymph Stage
Newly hatched centipedes, known as nymphs, resemble smaller versions of the adults. They have fewer legs than the adults and undergo several molts as they grow. Each time they molt, they gain additional legs and body segments.
6.3. Molting Process
Centipedes molt their exoskeletons as they grow. During the molting process, they shed their old skin and emerge with a new, larger exoskeleton. This process can take several hours or days to complete, and the centipede is vulnerable to predators during this time.
6.4. Adult Stage
Once centipedes reach the adult stage, they stop molting and focus on reproduction. Adult centipedes can live for several years, depending on the species and environmental conditions.
7. The Role of Centipedes in the Ecosystem
While centipedes can be a nuisance in homes, they play an important role in the ecosystem. They are predators that help to control populations of insects and other arthropods.
7.1. Predators of Insects and Arthropods
Centipedes feed on a wide variety of insects and arthropods, including cockroaches, spiders, ants, and termites. By preying on these pests, they help to keep their populations in check.
7.2. Soil Aeration and Decomposition
As they burrow through the soil, centipedes help to aerate it and improve its structure. They also contribute to the decomposition of organic matter by feeding on decaying plant and animal material.
7.3. Food Source for Other Animals
Centipedes serve as a food source for other animals, such as birds, reptiles, and amphibians.
