How to Get Rid of Isopods

Isopods are not insects but crustaceans, and are often referred to as "roly polies" or "pill bugs." They like to inhabit moist, shady environments and often remain hidden under objects during the day. Isopods are mostly beneficial because they break down decaying organic matter and circulate the soil. They can become garden pests, however, because they feed on young fruit and vegetable plants. If you discover isopods in your garden, treat them immediately for the health and safety of your plants.

Things You'll Need

Straw mulch
Insecticide
Caulk
Weather stripping

Instructions

- 1
  Lay some straw mulch over the soil of your garden around the plants as they ripen. The mulch will create a barrier between the soil and the isopods, keeping them from coming into contact with the ripening fruit.
- 2
  Apply an insecticide dust containing carbaryl or permethrin to your plants. Dust the soil around the roots of your plants with the insecticide for effective pest control. Re-treat as directed on the label.
- 3
  Reduce the moisture level in your garden to control isopod populations. Isopods can only survive in moist soil, so when your plants become ripened, water them only every other day to deter isopods.
- 4
  Remove piles of leaves, mulch, stones and other items lying on the ground beside your home. Isopods thrive in these places and can grow into great numbers if left untreated.
- 5
  Prevent isopods from entering your home. Seal cracks and crevices in your home's foundation with caulk and seal windows and doorways with window stripping.
