Natural Indoor Pest Control: Repelling Pill Bugs, Spiders, and Silverfish with Herbs and Habitat Modification

Indoor Herb Regimen

Charlotte's spider/silverfish/earwig-free home uses:

• Rosemary: 1-inch pieces on shelves, longer under appliances, near plumbing penetrations.
• Lavender: sprigs in closets, under beds, behind furniture.
• Cedar oil: trails on closet rods, baseboards, door frames (monthly).

Pill Bug (Roly-Poly) Biology & Management

• Crustaceans, not insects; need moisture; eat decaying matter.
• Reduce indoor humidity: vent fans, dryers vented outside, dehumidify crawl spaces.
• Remove exterior debris, leaf litter, boards, rocks near foundation.
• Caulk ground-level cracks.
• Corncob traps can capture them.
• Natural predator: Dysdera crocata spider (harmless to humans).

Yard Practices That Help

Cedar bark mulch broadcast over lawn repels many insects; may explain Charlotte's lack of pill bug issues. Cedar band around foundation deters termites.
