When Control is Needed

Indoor Invasions

  • • Found in laundry rooms or bathrooms
  • • Wandering into living areas
  • • During very wet weather periods

Garden Problems

  • • Damage to young seedlings
  • • Eating fruit touching the ground
  • • Large populations in mulched areas
  • • Chewing on tender plant roots

Gentle Management

Moisture Reduction

  • • Improve ventilation in damp areas
  • • Fix water leaks promptly
  • • Reduce mulch thickness near foundation
  • • Ensure proper drainage around home

Eco-Friendly Approach: Remember that pill bugs are beneficial decomposers! Consider relocation rather than elimination when possible.

Humane Removal

  • • Gently collect and move outdoors
  • • Use overturned pots as traps
  • • Relocate to compost areas
  • • Create barriers around sensitive plants
