Mulches provide shelter, moisture or food for many different insects and their relatives.
Most are beneficial. A few are potentially harmful, but their presence is generally not a cause for alarm or treatment. Predators and Recyclers Mulch provides a stable habitat where beneficial predators can find a steady source of food. Common predators that live and feed in mulch include rove beetles, ground beetles, lightningbug larvae and centipedes.
