Finding centipedes in the house can be concerning, especially when they scurry across a floor or wall. The good news is that safe centipede removal usually starts with small changes. Lower moisture levels, remove hiding places, close cracks and openings, and control the small insects that centipedes hunt.
The house centipede is the species frequently found indoors. It prefers damp, quiet areas such as a basement, crawl space, bathroom, laundry room, or storage area. A single sighting does not always mean you have a centipede infestation. Recurring sightings, many shed skins, or regular activity in several rooms suggest that the home has suitable shelter, moisture, and prey.
This guide explains how to control centipedes safely. It focuses on non-toxic pest control, moisture control, exclusion, and proper product use. These steps support pest prevention without putting children, pets, or household members at avoidable risk.
Reasons Centipedes Enter Canadian Homes
A house centipede enters a home for three main reasons: food, dampness, and protection. Outdoor conditions can force these pests indoors through small openings around doors, windows, pipes, and foundations. Warm indoor spaces also provide protection during cold weather.
Centipedes do not eat wood, fabric, or stored food. They hunt other insects and related pests. Their prey may include silverfish, spiders, cockroaches, ants, flies, and small larvae. If you see centipedes in the house regularly, the underlying issue may be a wider indoor pest problem.
Moisture plays a key role. A damp basement, wet crawl space, leaking pipe, or poorly ventilated bathroom gives centipedes the conditions they seek. They may hide behind stored boxes, under appliances, near floor drains, or in cracks along walls and floors.
Inspect areas that stay chilly and damp. Look under sinks, around sump pumps, beside water heaters, near laundry equipment, and along basement walls. Check for condensation, wet insulation, damaged seals, and water entering after heavy rain or snowmelt.
Are House Centipedes Dangerous?
House centipedes are not known for spreading disease in homes. Their presence can feel alarming, but they usually stay away from people and do not try to interact. They may help control some indoor pests because they feed on insects and spiders.
A centipede bite is possible, but it is rare. A house centipede has tiny jaws and usually cannot pierce human skin easily. If a bite occurs, it may cause short-term pain, redness, swelling, or itching. Wash the area with soap and water. Seek medical care if symptoms become severe, breathing problems develop, or the person has a strong reaction.
Pets may chase or eat a centipede. Most encounters cause little harm, although a pet could experience temporary mouth irritation or stomach upset. Contact a veterinarian if your pet shows repeated vomiting, facial swelling, weakness, trouble breathing, or unusual behaviour.
Human health concerns often relate less to the centipede itself and more to the conditions that attract it. Damp areas can support mould and other pests. Fixing moisture problems protects your home as well as limiting centipede activity.
Ways to Remove Centipedes Safely
For one or two visible centipedes, manual removal is often all you need. Avoid touching the insect, and do not squash it against a surface if you can avoid contact.
- Use a vacuum cleaner with a hose attachment to remove the centipede from floors, walls, corners, and ceilings.
- Empty the vacuum canister outdoors, or seal and discard the vacuum bag if the machine uses bags.
- For a slow-moving centipede on a hard surface, place a glass over it and push stiff paper underneath.
- Carry the glass and paper outside, then release the insect away from doors and foundation walls.
- Wear gloves when moving boxes, wood, stored materials, or other items from damp areas.
Glass and paper removal lets you stay in control without spraying a chemical. It also lets you inspect the area for moisture, webs, shed skins, and other insects. If the centipede is in a tight gap or an area that may contain other pests, vacuum it up instead.
Proper disposal is important. Do not leave a bag of vacuumed insects inside the home. Close it before placing it in household waste. Clean the vacuum attachment according to the manufacturer’s directions if you suspect a larger centipede infestation.
Lower Water Vapour and Humidity Indoors
Controlling moisture is one of the strongest ways to discourage centipedes. A dehumidifier can help lower indoor humidity in a basement, crawl space, or other damp room. Empty the tank regularly, or connect a drain hose if the model allows it.
Aim for indoor humidity that feels comfortable and does not create condensation on windows or cold pipes. A basic hygrometer can help you track conditions. The ideal setting varies by season and building, but persistent condensation and musty odours indicate that humidity reduction deserves attention.
Check for water leaks under sinks, behind toilets, around washing machines, near water heaters, and beside foundation walls. Repair small leaks quickly. A slow drip can keep a cabinet, floor, or wall damp for weeks.
Increase ventilation in bathrooms and laundry areas. Run exhaust fans during showers and for a short time afterward. Keep air moving around stored items. Avoid pushing boxes tightly against basement walls, since this can trap damp air and hide signs of water entry.
Check gutters, downspouts, grading, and exterior drainage. Water that collects beside the foundation can enter through weak points. If a crawl space remains wet after repairs, a building professional may need to evaluate drainage, vapour barriers, insulation, or sump equipment.
Close Entry Points Around the Home
After moisture is under control, close cracks and gaps that let centipedes get inside. Begin with the lower parts of exterior walls, doors, windows, utility openings, and areas where pipes run through masonry.
Use caulking around fixed gaps in window frames, trim, pipes, and baseboards. Select a product designed to the surface and follow its curing instructions. Do not seal an active water leak before repairing its source.
Install weatherstripping around exterior doors that show visible light or let in a draft. A properly fitted door sweep can close the gap beneath a door. Keep the sweep in good condition, since worn rubber or brush material leaves an easy route indoors.
Inspect window screens for tears and loose helpful site edges. Fix or replace damaged screens, especially on basement windows and windows near damp ground. Check vent covers and make sure they fit tightly while still letting the ventilation system to work as designed.
Foundation cracks deserve careful attention. Small gaps may need suitable masonry repair material, while larger or recurring cracks may signal movement or water pressure. Ask a qualified building professional to assess significant cracks, bowing walls, or ongoing seepage.
These exclusion steps help with long-term centipede prevention. They also reduce entry by spiders, ants, flies, and other pests that can become food for centipedes.
Get rid of Food Sources and Hiding Places
Centipedes remain where prey and shelter are easy to find. To reduce food sources, inspect areas where silverfish, spiders, cockroaches, ants, and other insects may shelter. A centipede sighting can be a useful clue that these pests are active in the area.
Limit indoor pests by storing food in sealed containers, removing crumbs, wiping spills, and taking out waste regularly. Repair plumbing leaks and remove damp cardboard. Silverfish often flourish in humid storage areas, while cockroaches may gather near food, water, heat, and appliance motors.
Spiders can form hiding places and indicate that other insects are nearby. Remove webs from corners, window wells, storage rooms, and basement ceilings. This does not remove every insect, but it helps you track activity and limit shelter.
Clear clutter from floors and walls. Cardboard boxes, unused clothing, newspapers, firewood, and garden materials can provide dark spaces for centipedes and their prey. Store items in sealed plastic containers on shelves, leaving room for checking and air movement.
Keep outdoor materials away from exterior walls. Leaves, mulch, boards, and stacked items can trap moisture beside the foundation. A clear inspection strip makes it easier to spot cracks, gaps, damp patches, and insect movement.
House Centipede Management Without Pesticides
Low-toxicity pest control works best when you pair several minor changes. Sticky traps can help confirm where centipedes pass. Place them along basement walls, behind appliances, near storage areas, and beside suspected entry points. Keep traps away from children and pets, and inspect them often.
Physical removal is suitable for isolated sightings. A vacuum cleaner picks up visible insects without leaving pesticide residue. Follow this method with moisture reduction and sealing work so more centipedes do not replace the ones you remove.
Diatomaceous earth may help in low-moisture, protected cracks and gaps. Use only a product labelled for pest control, and follow the directions on the package. Avoid creating dust. Do not apply it where children, pets, or household members could inhale or disturb it. Never spread large amounts through living areas.
Integrated pest management combines inspection, monitoring, sanitation, exclusion, moisture reduction, and carefully selected treatments. It does not rely on spraying every centipede you see. Instead, it targets the conditions that support the pest.
A practical plan may look like this:
- Note where and when you see centipedes.
- Place sticky traps to map activity zones.
- Repair water leaks and improve ventilation.
- Remove clutter and limit indoor pests.
- Seal cracks and gaps after surfaces are dry.
- Inspect the area after one to two weeks.
This process helps you distinguish a one-time visitor from recurring centipede sightings. It also reduces the chance that you will apply a product without addressing the cause.
Using Pest Control Products Safely in Canada
If home repairs and non-chemical methods do not control the problem, read the pesticide label before buying or applying any product. The pesticide label is a legal set of instructions. It states where the product may be used, which pests it controls, how much to apply, and what safety steps to follow.
In Canada, verify that the product is approved for the intended use. Health Canada oversees pest control products and lists registration information. A domestic-class pesticide is intended for use by household consumers, but it still requires safe handling.
- Read the full label before opening the package.
- Obey label directions exactly, including dilution and application limits.
- Keep children and pets away from treated areas as directed.
- Clear or cover food, dishes, pet bowls, toys, and bedding before treatment.
- Do not apply outdoor products inside.
- Do not mix products unless the label specifically allows it.
- Store products in their original containers, away from heat and food.
Approved pest control products can pose risks when used incorrectly. More product does not mean stronger control. Never spray mattresses, clothing, food preparation surfaces, or air vents unless the label clearly permits that use.
If you feel uncertain about product selection, application, ventilation, or re-entry time, contact a licensed pest control professional. Ask what product class will be used, where it will be applied, and what preparation your household needs.
Mosquito Man is one business name a homeowner may see when researching pest services. Verify the provider’s licence, insurance, treatment details, and safety instructions before approving work.
When to Contact a Pest Control Professional
Contact a professional if you notice a recurring infestation, centipedes in several rooms, activity that continues after moisture repairs, or signs of cockroaches and other prey insects. A professional can also help when centipedes are entering from a crawl space, wall void, foundation, or inaccessible drainage area.
A pest inspection should detect more than the visible insects. Ask the technician to check moisture, entry points, harborage areas, and the insects that centipedes hunt. A clear inspection helps prevent treatment that only addresses the surface symptom.
A suitable pest management plan may include repairs, monitoring, sanitation, exclusion, and professional treatment. The plan should describe what will happen before, during, and after service. It should also identify any preparation steps and precautions for children, pets, older adults, and people with respiratory sensitivities.
Ask whether the company recommends integrated pest management. This approach places prevention and physical controls before routine chemical application. If a treatment is needed, the professional should use the least-risk method that fits the site and the pest.
Professional treatment is especially useful for a high number of centipedes, hidden moisture, difficult access points, or a recurring pest problem that you cannot trace. Keep records of sightings and repairs. Photos can enable the technician to understand patterns before the inspection.
Frequently Asked Questions
How do I prevent centipedes out of my Canadian home?
Reduce moisture, repair water leaks, improve ventilation, and use a dehumidifier where indoor humidity stays high. Close cracks and gaps with suitable caulking, install weatherstripping around doors, repair window screens, and address foundation cracks. Remove clutter and reduce silverfish, spiders, cockroaches, and other prey insects. These steps create a practical centipede prevention plan.
Are house centipedes dangerous to people or pets?
House centipedes usually avoid people and are not known for spreading disease in homes. A centipede bite is uncommon and may cause temporary pain, redness, or swelling. Pets may have mild mouth or stomach irritation after eating one. Seek medical or veterinary help for severe swelling, breathing problems, weakness, or other serious symptoms.
Why are centipedes appearing in my basement?
Basement centipedes often appear because the area offers moisture, darkness, shelter, and prey. Check for damp walls, condensation, plumbing leaks, poor drainage, cardboard clutter, silverfish, and spiders. Use sticky traps to locate activity, then improve moisture control and seal entry points. A professional pest inspection can identify hidden sources.
What attracts centipedes inside in Canada?
Dampness, moist air, cool sheltered areas, and food draw centipedes indoors. They may get inside through foundation cracks, gaps around doors and windows, pipe openings, or damaged screens. Their presence can also point to prey insects such as cockroaches, silverfish, spiders, ants, and flies. Remove food sources and fix damp conditions rather than using sprays alone.
How can I manage centipedes without using pesticides?
Use a vacuum cleaner for insects you can see, removal with glass and paper when practical, sticky traps for monitoring, and careful physical removal. Reduce humidity with ventilation and a dehumidifier, repair water leaks, clear clutter, and close cracks and gaps. Diatomaceous earth may be appropriate in limited dry areas when the label permits it and exposure is controlled. Integrated pest management combines these methods to support pest control without pesticides.
