The advantage of residing in the city of Mississauga is that you are blessed with the view of a beautiful lakefront, good schools, and four entirely different seasons. Nevertheless, this has its negative aspect: house centipedes that are known to live in the basement, bath, and laundry rooms. They are hasty-moving animals which move on numerous legs, and anyone can be startled by them, especially when they run across the floor in the dark. Even though they are not typically harmful to people, no one would like them to stay with them. It is an exhaustive manual on the reasons why centipedes seem to be common in houses in Mississauga, methods of repelling them, and the most convenient and least harmful ways of ensuring that the centipedes are permanently removed.
Why Centipedes Love Mississauga Homes
The reason why house centipedes (Scutigera coleoptrata) flourish in Southern Ontario is that the presence of humid summers and wet springs is the ideal climate in which these insects prefer to feed on spiders, ants, bed bugs, termites, and cockroaches. The older neighbourhoods, such as Port Credit, Streetsville, Cooksville, and Erin Mills in Mississauga, tend to have homes with stone foundations, fieldstone walls, or unfinished basements that remain damp all year round. Into the ground-floor doorways and into the weeping tiles which add moisture, and the ravines or conservation areas that are next (such as the Credit River valley or Etobicoke Creek), and you have centipede highway right into your home.
In the fall, centipedes are more likely to enter homes during late summer and fall, but the heavy rainfall at any time of the year also makes them seek shelter in houses. They settle and multiply as soon as they have found a wet, dark place and a large number of insects to nourish themselves.
Are House Centipedes Dangerous?
The common house centipede, which has long antennae and 15 pairs of legs, is a problem for most residents of Mississauga. A bonus: they do not bite people very often, and when doing so, it is a slight sting of a bee, which dissipates in time. They are beneficial, as they feed on silverfish, carpet beetles, and other actual pests. Nevertheless, it is never welcome that they race on your bedroom wall at 2 am.
Signs You Have a Centipede Problem in Your Mississauga Home
- Seeing one or two occasionally is normal in older homes.
- Finding them regularly in bathrooms, laundry rooms, or basement rec rooms means the population is growing.
- Spotting them upstairs (main floor or bedrooms) usually signals a large infestation downstairs.
- Discovering shed legs or body parts, they drop legs to escape predators.
Prevention: Keep Centipedes Out Before They Get In
The best centipede control starts outside your home. Reduce moisture and block entry points so they never make it indoors.
Here’s a straightforward checklist that works wonders for Mississauga homeowners:
- Use a dehumidifier in the basement and keep humidity below 50%; fix leaking pipes, dripping taps, and wet spots under sinks; clean eavestroughs and extend downspouts at least 6 feet away from the foundation; install window well covers and grade soil away from the house; seal cracks in foundation walls, around windows, and where pipes enter the home; replace torn window or door screens; vacuum regularly (especially baseboards and corners) to remove their food sources; reduce outdoor lighting at night or switch to yellow “bug lights” centipedes hunt insects attracted to white lights; store firewood off the ground and away from the house.
DIY Centipede Control Methods That Actually Work
Many Mississauga residents try do-it-yourself options first. These methods help reduce numbers but rarely solve a bigger infestation.
| Method | How to Use | Effectiveness | Pros | Cons |
| Sticky traps | Place along baseboards and behind furniture | Good for monitoring | Non-toxic, shows other pests too | Doesn’t kill the breeding population |
| Diatomaceous earth (food-grade) | Dust lightly in cracks and crevices | Moderate | Safe around kids & pets | Slow-acting, messy |
| Essential oil sprays (peppermint, tea tree) | Mix 10–15 drops with water in a spray bottle | Low to moderate | Pleasant smell | Needs frequent re-application |
| Vacuuming | Use the crevice tool regularly | Excellent short-term | Instant removal | Doesn’t prevent re-entry |
| Reducing prey insects | Control spiders, ants, and silverfish first | Very high long-term | Solves root cause | Takes time |
When to Call Professional Centipede Control in Mississauga
If you continue to see centipedes after two or three weeks of preventive measures, or if you see them up the stairs or in more than one room, you need to call in the professional. The licensed pest control technicians in the city of Mississauga know the local soils, areas that are most susceptible to different insect pests, townhouses, and high-rise condos, and what products are effective in Ontario to deter the family or pets.
A proper treatment usually includes:
- Thorough interior and exterior inspection
- Targeted application in key harbourage areas
- Sealing advice specific to your property
- Follow-up visit if needed
Many local companies offer eco-friendly and low-odour options perfect for homes with children, seniors, or pets.
Seasonal Centipede Patterns in Mississauga
- April–June: Spring rain pushes centipedes indoors.
- July–August: Peak outdoor population, you may see more trying to enter.
- September–November: Biggest indoor invasion as temperatures drop.
- December–March: Fewer new entries, but established ones stay active year-round in warm basements.
The later in the summer or at the beginning of the fall, the better you stand to prevent them before they fix themselves in their winter quarters.
Special Considerations for Mississauga Neighbourhoods
Older houses within the Lorne Park, Mineola, and Lakeview areas tend to have fieldstone foundations, which are constantly damp and perfect homes for centipedes. Recent constructions around the 403, 407, or QEW have overgrown woodlands or wetlands, which expose centipedes to foundations. The centipedes may be found in the condos and townhouses around Hurontario or Dundas, travelling through shared walls or garage doors.
Regardless of where you are located in Mississauga, whether it is Clarkson to Meadowvale, Erindale to Lisgar, the same rules of prevention can apply.
Keep Your Family Comfortable All Year Round
One can never be inconvenienced to be at home because of creepy crawlies. The centipede problem can be resolved with the appropriate level of moisture control, sealing and (in some cases) professional help to restore the pleasure of having a centipede-free home.
