All pests can be found in an organic farm. They all just need to be dealt with differently - but there are organic solutions for most pests.
Many kinds of insect pests destroy forests by eating the shoots and spreading diseases.

For example, carnivorous plants meet nutritional requirements -- unmet in nutrient-poor, severe environments -- by consuming pesty arthropods.
Plant vegetable varieties that have been proven to be resistant to disease and pests. Organic Insecticides are more effective controlling pests and are safer and easier to use.
