There are many “good” insects you will want to encourage to visit your yard and garden. Ants, bees, hover flies and other insects are important pollinators. The adult and larval stages of dragonflies and ladybugs, the larva of green lacewings, and nearly all spiders prey upon “bad” bugs. These natural predators won't eradicate all undesirable insects but they will help reduce their populations. Be cautious when using insecticides since they harm beneficial insects, as well as nuisance insects.
