Centipede & Millipede Control

While centipedes and millipedes are both multi-legged insects commonly found in Calgary homes, they are quite different in their behavior and the risks they pose. Centipedes are fast-moving predatory insects that feed on other small insects and spiders, while millipedes are slow-moving scavengers that feed on decaying organic matter. Although their behaviors differ, both species are attracted to moisture-rich environments and require a similar overall approach to elimination. At Preventive Pest Control, our Calgary technicians accurately identify the species present on your property and tailor the treatment accordingly to ensure the most effective results.

For the most part, centipedes and millipedes found in Calgary homes do not pose a serious threat to human health or pets. However, certain centipede species are capable of delivering a mildly painful bite if handled or threatened, which can cause localized swelling and irritation. Millipedes, while not biters, can release a defensive secretion when disturbed that may cause mild skin or eye irritation. While neither species is considered highly dangerous, their presence indoors is always worth addressing promptly, particularly in homes with young children or pets who may come into contact with them.

If you are regularly encountering centipedes or millipedes inside your Calgary home, it is almost always a sign of excess moisture somewhere on your property. These pests are strongly drawn to damp, humid environments and commonly enter homes through gaps in foundations, poorly sealed doors, and openings around utility lines. Basements, crawl spaces, bathrooms, and laundry rooms are among their preferred indoor locations. Addressing the underlying moisture conditions on your property is a critical part of achieving long-term control, which is why Preventive Pest Control takes a comprehensive approach that goes beyond surface-level treatment.

While there are DIY products available that may reduce centipede and millipede activity temporarily, they rarely deliver lasting results on their own. Without addressing the moisture conditions, exterior harborage areas, and entry points that are attracting these pests to your Calgary property in the first place, the problem is likely to keep returning season after season. Professional centipede and millipede control from Preventive Pest Control targets the infestation at its source and puts a comprehensive prevention strategy in place to stop these pests from coming back, delivering the kind of long-term relief that DIY methods simply cannot match.

Centipede and millipede activity in Calgary tends to peak during the spring and fall seasons when cooler outdoor temperatures and increased rainfall drive these moisture-loving pests to seek warmth and shelter indoors. Heavy rainfall periods can also trigger sudden and significant millipede migrations toward the foundations of Calgary homes and businesses. While these pests can be encountered year-round in properties with persistent moisture issues, seasonal spikes in activity are common and often catch homeowners off guard. Scheduling a preventative inspection with Preventive Pest Control before these peak seasons is a smart and proactive way to stay ahead of the problem.

Long-term prevention is at the core of everything we do at Preventive Pest Control.
