Nuisance Pest Control: Centipedes, Millipedes & Earwigs

Common Habitat of Centipedes, Millipedes & Earwigs:

Centipedes, millipedes, and earwigs thrive in damp, shaded environments. They are commonly found in mulch beds, leaf litter, under stones, around foundations, and in areas with excess moisture. After heavy rainfall or temperature shifts, they may migrate indoors through foundation cracks, door thresholds, basement windows, and utility openings. Indoors, they are most often seen in basements, crawl spaces, bathrooms, and other humid areas.

Risks & Diseases:

Occasional invaders are primarily nuisance pests and generally do not cause structural damage. However, their presence indoors can be alarming. Some centipede species can bite if handled, though bites are rare and typically mild. Millipedes may emit an unpleasant odor or leave stains if crushed. Earwigs may damage garden plants outdoors but do not typically cause significant indoor damage. While they do not pose serious health risks, recurring activity often indicates moisture or exterior conditions that should be addressed.

Signs of Centipedes, Millipedes & Earwigs’ Infestation:

Homeowners may notice individual pests crawling along walls, floors, or near windows and doors. Activity often increases after heavy rainfall or seasonal transitions. Frequent sightings in basements or bathrooms may signal excess humidity or small entry points around the home’s exterior.

Methods of Occasional Nuisance Pest Prevention:

Preventing occasional invaders begins with moisture control and exclusion. Reducing mulch depth near foundations, clearing leaf litter, improving drainage, sealing foundation cracks, and installing proper door sweeps can significantly reduce entry. Managing interior humidity levels in basements and crawl spaces also helps deter activity. Proactive exterior perimeter treatments are often the most effective way to prevent seasonal migrations indoors.
