Establish deep soil beds for better rooting IPM is not a strictly organic approach to pest control. Residual pesticides remain effective in the environment for days, weeks, or months, which impacts beneficial organisms and pests. The impact of gardening and pest management decisions often extends far beyond your property lines. Concern for the environment, development of pesticide resistance, problems with pesticide safety, and the effects of pesticides on nontarget organisms have sparked interest in finding alternative means of controlling pests. One approach is to identify, establish, and conserve beneficial organisms.
Predators attack and consume pests directly.
They are usually larger and more active than their prey. For example, insect predators tend to move rapidly and have large eyes and forward-pointing mouthparts. Parasites use pests as food sources for their young. For example, insect parasites lay their eggs in, on, or near the pest insect. The offspring then grow in or on the host, and eventually kill it.
