How do you handle Insects?

[nova]

A lot of time what happens is that when you start doing the internal garden or say container garden. You end up with random insect attack. Which is natural and also some of the time required for the soil. I wonder how the insects which are bad for the plants can be handled. As in those who are predatory for the plants. How do you managed them and get rid of them without affecting the plants. 

How do you handle insect attacks in the garden?

Diatomaceous Earth works great, especially for indoor plants. Usually put it on top of the soil. You can sprinkle it on the leaves also.
