A variety of beneficial insects and mites are available for release in the garden, nursery or orchard to deal with a range of pests in a safe and effective way. These biological agents are released to predate upon the pest species and to re-establish a balance. Once a population is established, the numbers of available pests will control the number of available predators that will control the number of available pests and so on. The following table lists useful species, their uses and their suppliers.
