6. Hunting and parasitic wasps
There are hundreds of species of wasps, including many that are so tiny you can barely see them. These mini-wasps often attack the eggs of pests, and are one of the most important insect groups that provide control of garden pests. They can be attracted by growing by pollen and nectar plants.

7. Spiders: All spiders feed on insects and are very important in preventing pest outbreaks. The spiders normally found in gardens do not move indoors, nor are they poisonous. Permanent perennial plantings and straw mulches will provide shelter and dramatically increase spider populations in vegetable gardens.

8. Tachinid Flies
Although they look similar to house flies, tachinid flies are very important enemies of cutworms, armyworms, tent caterpillars, cabbage loopers, gypsy moths, sawflies, Japanese beetles, squash bugs, and sowbugs. Grow pollen and nectar plants to attract them.
