Centipedes in your house in Portsmouth are there because they are feeding on other insects. House centipedes are predators that hunt cockroaches, spiders, silverfish, ants, and other small pests. Their presence indicates an underlying insect population in your home. Centipedes are also attracted to moisture, so damp basements, crawl spaces, and bathrooms are their preferred habitats. The most effective way to reduce centipedes is to eliminate the pest populations they feed on through comprehensive pest control, combined with moisture reduction through leak repairs, improved ventilation, and dehumidifier use. Professional perimeter treatments and sealing entry points around the foundation provide additional control.
