Usually you can find a non-toxic control which will drop the pest population to an acceptable level, and then you can discontinue controls while you continue monitoring. The choice of what you grow will determine to a large extent what pests you have to deal with. Some plants have almost no pest problems, while others almost seem to come with the insects included. As much as possible, choose to grow the species that are least prone to damage. This doesn't necessarily mean you can't grow your favorite flowers or vegetables, but you may need to look for slightly different varieties.
Healthy plants are less susceptible to insect attack than unhealthy ones.
Try to grow plant species and varieties which are well-adapted to your climate, soil conditions, and available light levels. They will be more vigorous than species which have to struggle to survive. Plant a variety of different kinds of vegetables and flowers so that no single pest can destroy your garden. Diversity in the garden encourages a rich mixture of pests and predators which can better maintain a dynamic balance. Timing Sometimes pest problems in annuals can be reduced by planting at times when pest populations are low.
