Biological pest controls

These are the naturally occurring or deliberately introduced insect or disease parasitoids, predators, or microbes that work to control pests or diseases. These organisms are introduced where they make sense. Examples of these natural controls are lacewing insects that eat aphids and parasitic wasps that prey upon other insect pests. More importantly, using the IPM approach helps to ensure that natural occurring controls such as these are affected as little as possible by our activities. This helps to keep these natural pest controls in place and working to keep our landscapes healthy.
