Or you may catch the strangest looking bug that you've ever seen in your whole life and be ready to take it to the zoo for identification. These pests have been around for a very long time and really do have a place in nature. Some are part of the food chain, as birds will land and eat them. Some eat dead, decaying matter and turn it into the a form of compost for the soil. You just have to realize that their presence is not harmful, and there are ways to discourage them from choosing your garden as home base.
Organic gardeners are painfully aware of pests in the garden.
There are some of us who actually grow extra plants for the bugs to have as their own. We can set up barriers to marauding insects as good as any WWII fortification. Netting a tree or using row covers for our young plants to provide them extra protection is easy to do. Helping snails and slugs commit suicide in a beer bug bath brings joy to our lives. There are many biologic controls available to the home gardener.
