Attracting beneficial insects

There are two ways to get beneficials into your yard. You can order them from a supply house such as Evergreen Grower's Supply or Arbico-Organics or you can plant flowers and other plants that will provide habitat for the beneficials.

What are beneficial insects?
Beneficial insects are those who either pollinate flowers or eat other insects that damage plants. If you spend time watching in the garden, you are likely to seem some of each. The traditional American way to deal with insects has been to spray them with some kind of insecticide, whether organic or inorganic. Unfortunately, this not only kills the harmful insects, it also kills the beneficial ones who might otherwise limit the number of harmful ones.
