Centipedes are among the household pests that can startle anyone who spots them darting across a floor or a wall. Although they rarely harm humans, their presence often signals a larger pest problem, as centipedes feed on insects. In Canada, where climates vary dramatically between provinces, centipedes can thrive indoors during colder months and become a recurring nuisance if not handled properly. Understanding how to manage centipedes control is essential for maintaining a clean, pest-free home or workplace.
This guide shows Canadians what they need to know about centipedes: habits, risks, prevention, and control. It follows current pest management standards and 2025 SEO best practices.
With that foundation, let’s start by asking: What Are Centipedes?
Centipedes are elongated arthropods with multiple legs one pair per body segment. Despite their name, they don’t actually have 100 legs; depending on the species, they can have anywhere from 30 to 350. The most common species found in Canadian homes is the House Centipede (Scutigera coleoptrata), easily identified by its long legs and fast movements.
Centipedes are nocturnal predators that feed on other insects such as spiders, silverfish, cockroaches, and ants. Their presence often indicates that your home has a thriving insect population, something that needs to be addressed alongside any centipede infestation.
Are Centipedes Dangerous?
In general, centipedes are not dangerous to humans or pets. They have venomous claws (forcipules) that they use to paralyze prey, but bites from them are extremely rare and typically harmless, causing only mild irritation or swelling. However, their sudden appearance and rapid movement can cause distress for many homeowners.
Centipedes can multiply and hide in humid, dark spaces, becoming a nuisance in basements and bathrooms if unaddressed.
Common Centipede Species in Canada
Canada hosts several species of centipedes, though only a few tend to invade homes. Understanding which type you’re dealing with helps determine the best centipede control method.
- House Centipede: The most frequent intruder in Canadian homes. It’s yellowish-gray with long, thin legs and moves extremely fast.
- Stone Centipede: Typically found outdoors in gardens, under rocks, or in moist soil. They occasionally wander indoors in search of shelter.
- Soil Centipede: Lives primarily in soil or under debris and feeds on small insects. Rarely seen inside homes.
Of these, the house centipede is the most adaptable to indoor environments and can live its entire life inside buildings if conditions are suitable.
Why Centipedes Enter Homes
Centipedes prefer environments that are moist, dark, and rich in insects the perfect combination found in many basements, bathrooms, and laundry areas. In Canada, seasonal changes also play a big role. During fall and winter, outdoor centipedes move indoors to escape the cold and find reliable food sources.
Here are the main reasons they invade homes:
- Moisture and humidity: Damp basements, bathrooms, and leaky pipes provide ideal conditions.
- Insect activity: Centipedes hunt prey, including ants, spiders, and cockroaches.
- Shelter from weather: They seek warmth and cover during colder months.
- Clutter and hiding spaces: Cardboard boxes, storage bins, and cracks in walls provide places to hide.
Knowing these factors helps design a long-term preventative centipede control plan.
Signs of a Centipede Infestation
Centipedes don’t form large colonies, so infestations often go unnoticed until one is seen. There are signs that suggest a larger issue.
- Frequent sightings of centipedes in bathrooms, basements, or near drains.
- Increased insect activity (their food source).
- Shed legs or exoskeletons found near walls or baseboards.
- Tiny bite marks on smaller household pests (a sign of centipede predation).
Centipedes are most active at night, making infestations harder to detect.
DIY Centipedes Control Methods
For minor issues, several do-it-yourself solutions can help reduce centipede populations and discourage their return.
- Reduce Moisture
Centipedes thrive in humid environments. Use dehumidifiers in basements and repair any plumbing leaks or condensation buildup. Ventilate bathrooms and laundry rooms properly.
- Seal Entry Points
Inspect walls, floors, and windows for cracks or crevices. Use caulking or weatherstripping to seal these openings, blocking centipedes and their prey from entering.
- Remove Clutter
Clear out piles of boxes, newspapers, and wood where centipedes can hide. Keep storage spaces clean and dry.
- Eliminate Food Sources
Address the root cause other insects. Regularly clean crumbs, fix leaks that attract pests, and schedule pest control for ants or roaches if necessary.
- Use Natural Deterrents
Certain natural repellents, such as essential oils (tea tree, lavender, or peppermint), can discourage centipedes. Mix with water and spray around baseboards or damp corners.
DIY methods work for mild issues, but persistent problems usually need professional help.

Hiring professionals ensures a thorough approach addressing both centipedes and the insects they feed on while following Canadian pest management regulations and environmental safety standards.
How to Prevent Centipedes Long Term
After centipedes are gone, focus on prevention. If you live in a humid or older home, adopt regular maintenance practices to keep pests away year-round.
- Maintain proper ventilation: Keep air flowing in basements and bathrooms to prevent humidity buildup.
- Use a dehumidifier: Especially useful in coastal and colder provinces where indoor humidity stays high.
- Seal foundation cracks: Check your home’s foundation, baseboards, and around utility pipes.
- Store firewood away from the home: Centipedes often hide in wood piles, so keep them at least 20 feet from your building.
- Regular pest inspections: Schedule seasonal inspections to detect pest activity early.
Consistent prevention saves time and money. Protect your property from unwanted pests.
Environmental Impact and Safety
Modern centipedes control methods in Canada emphasize environmental safety and humane pest management. Reputable pest control companies use eco-friendly treatments and avoid broad-spectrum chemicals that can harm beneficial insects. Integrated Pest Management (IPM) techniques focus on long-term prevention, habitat modification, and minimal chemical use.
Homeowners are also encouraged to use non-toxic options, such as diatomaceous earth or natural repellents, to control pests while preserving ecological balance. These environmentally conscious strategies reflect Canada’s growing commitment to sustainable pest management.

The Canadian Climate Factor
Centipede activity varies across Canada depending on the region. In coastal provinces like British Columbia, humidity attracts centipedes year-round. In colder provinces like Alberta or Manitoba, they often migrate indoors in winter for warmth. Recognizing these seasonal patterns helps homeowners prepare proactive pest control measures suited to their location.
Final Thoughts
Centipedes may not be the most dangerous pests, but their presence is unsettling and often signals a larger insect issue. Effective centipede control in Canada means addressing both the centipedes themselves and the conditions that attract them moisture, darkness, and prey.
