Many species of flowers attract natural insect predators and pollinators to the garden. Just last year I had some mint growing in the garden that I let go to flower and the amount of insects that would end up buzzing around just the one plant was truly amazing. Around that plant alone I saw honeybees, parasitic wasps (the good guys) and many other beneficial insects.

Having areas of your garden for the good guys will keep the bad guys (aphids, cabbage worms, mites, and leaf miners) away. Herbs in general are great natural insect deterrents because they give off scents which deter pests from other surrounding plants.

So let some of your herbs flower and welcome some beneficial insects into your garden!
