Professional Earwig Extermination Across Ontario
Earwigs are one of the most commonly encountered nuisance insects in Ontario homes, especially during the warm months from late spring through early fall. While these small, dark brown insects with their distinctive tail pincers (cerci) are completely harmless to humans, their appearance is unsettling, and when they invade in large numbers, they become a genuine household nuisance. Ontario homeowners frequently find earwigs in bathrooms, basements, kitchens, laundry rooms, and any space where moisture collects.
ZeroBite Pest Control provides comprehensive earwig control that addresses both the interior infestation and the exterior conditions that drive earwigs into your home. Our combined interior and exterior barrier treatment creates a protective zone around your foundation while eliminating earwigs that have already made their way inside. This dual approach is far more effective than treating the interior alone, because earwigs are primarily outdoor insects that invade homes from surrounding landscaping and garden areas.
Why Earwigs Invade Ontario Homes
Earwigs are moisture-seeking insects that live naturally in the organic debris layer of gardens, mulch beds, and leaf litter. They thrive in the damp darkness under stones, landscape timbers, potting containers, and garden equipment. Ontario’s humid summers provide ideal outdoor conditions, but during periods of extreme heat, drought, or heavy rainfall, earwigs seek shelter inside nearby structures. They enter through cracks around doors and windows, gaps under siding, foundation cracks, utility pipe penetrations, and even through weep holes in brick veneer.
Landscaping practices often contribute to the problem. Thick mulch layers against foundations, garden beds immediately adjacent to exterior walls, ground-level window wells, and downspout discharge near the building all create conditions that attract earwigs close to potential entry points. Once inside, they gravitate to bathrooms, basement corners, under sinks, behind appliances, and in laundry areas where moisture is available.
Harmless but Unsettling
Despite their intimidating appearance, earwigs pose no threat to human health. Their cerci (pincers) are used for defence against other insects and during mating rituals, not for attacking people. They do not bite, sting, or transmit diseases, and the old myth that earwigs crawl into human ears is exactly that — a myth with no basis in reality. However, earwigs can damage garden plants and seedlings, feeding on soft-leaved plants, flower petals, and young vegetables at night. For Ontario gardeners, this plant damage is often the more significant concern.
Entry Prevention Is Key
The most effective long-term earwig strategy is preventing entry in the first place. ZeroBite’s barrier treatment creates a treated zone around your home’s perimeter that earwigs cannot cross without encountering residual product. Combined with sealing entry points and modifying landscaping habits, this approach provides season-long protection without repeated indoor treatments.

Landscaping Tips to Reduce Earwig Attraction
Simple changes to your landscaping can dramatically reduce earwig pressure on your home. Keep mulch layers thin (under 5 cm) and maintain a 30 cm clear gravel or bare-soil band between mulch and your foundation. Remove leaf litter, fallen fruit, and garden debris regularly. Ensure downspouts discharge at least 1.5 metres from the foundation, and grade soil so water drains away from the building. Replace exterior white lights with yellow sodium-vapour or LED bulbs that attract far fewer insects, reducing the food source that draws earwigs to your doorways at night. ZeroBite provides a detailed, property-specific landscaping assessment as part of our preventive plan.
