How To Use Insects To Fight Other Pests For Total Natural Pest Control

Guest post by New York City PestControl

The introduction of predators and other species to control the pests in a garden is called biological pest control. As opposed to the health risks of chemicals, people needn’t worry about working with these biological agents.

Using biological means to control pests is not a new concept. Many of the gardeners know that ladybugs are very effective at getting rid of Aphids. There are many beneficial insects out there, but, they are not as famous as Ladybugs because some of them have daunting names like Trichogramma wasp. When people hear such names, they immediately come to a conclusion that they are bad pests.

You must have heard a lot about these so-called "beneficial insects", but, you would have had your doubts. So why don’t you attract them to your garden and see the results for yourself?

Here is a list of some of the most common beneficial insects which help to control pests

1.    Minute Pirate Bugs

Assasins are known as the ninja bug because they are sneaky, swift and brutal. They prey on insects including flies, caterpillars, beetles, and mosquitoes. These bugs work round the clock and are seen on shrubs and little plants. Assassin bugs are found in woodland areas, along roads, and trails. Since these bugs move slowly, they are easy to spot. Assassin bugs will bite if they are disturbed. You don’t have to worry because their bite is not lethal but, they are painful.

Color: brown, green, or black

How to attract them? They stick to small flowering plants like Queen Anne's Lace, and varieties of daisy.

Damsel bugs will eat any insect that is smaller than them, even the beneficial ones. And sometimes when they can’t find food they will eat each other. They prey on aphids, caterpillars, spider mites, and treehoppers. Occasionally, they feed on leaves but, they won’t cause any harm to the plants. Commercial suppliers do not sell these bugs. So you have to grow certain varieties of plants to attract them.

How to attract them? Hoverflies are active in any season. So plant a variety of flowers that are suitable for every season. Grow lavender, marigolds, mint, statice, sunflowers. Also, you can leave carrot and yarrow leaves between crops.
