Beneficial Insects

Beneficial insects are something you want, because in any backyard or small farm ecosystem, it is important to welcome all life forms as much as possible. Even though Ants herd and spread Aphids, they also destroy Fruit fly,  Housefly larvae and many other harmful insect pests, and keep the garden clear of much debris. Many Wasps parasitize pests such as Aphids and grubs.

Toads eat Earwigs, Slugs, Cutworms, and other pests (up to 10,000 in three months). Yet for toads to be successful in your garden they need hiding places away from cultivated areas.

Many birds consume insect pests by the hundreds in a single day. I always look forward to our Cliff Swallows retuning to our property each year, because any flying insect is pretty much lunch. It's amazing how active they are at catching insects in mid-air… all day long!

Even the tiny Bat is our friend in the garden or farm and should be encouraged to stay. A Bat will consume 1,000 Mosquitoes in a single night and is harmless to animals and humans.

The Secret to Attracting Beneficial Insects to your Organic Garden

The secret to attracting the beneficial insects is simple, biodiversity. Along side your vegetables grow as many flowering perennials as you can. Mix it up. Also, something I believe will be taught and talked about in the coming future will be planting more plants that are native to your area.

When you have favorable insects evolving for thousands of years on native flora, then to me, it makes sense to continue that process by planting native plants in and around your organic garden that will attract, feed and house these favorable insects. Natives also require significantly less water and little or no fertilizer.

Successfully utilizing insect predators and parasitoids as a biological control is also achieved through conservation and augmentation.
