Beneficial Insects for the Garden

Whenever you see an insect in the garden, your immediate thought process leads you to eliminate the insect. This approach can sometimes deprive you of a guardian of your garden. Yes, you heard right, there are some insects that are beneficial for your garden in a way that they can get rid of the actual harmful pests.

They are natures little helping hand for your garden. It also doesn’t hurt that they do this work for free which would otherwise have to be done with some expensive and rather counter-productive chemicals.

Most of these helpful insects help by eliminating the more harmful pests in your garden and they can are attracted to your garden if you have certain plants present in your garden.

This method is completely natural and healthy for your garden that provides all of the benefits of pesticide without any of the harmful side effects.

Plus, in recent studies it has been shown that most of the insects found in the garden are starting to develop a resistance to most of the pesticides which by the way, not only destroy the harmful insects but also the beneficial ones.

This method makes sure that the harmful bugs are eliminated because let’s face it, there really isn’t much a tiny bug can do to prevent being eaten by a predator.

Important Things to Keep In Mind

Before you start filling your garden with these beneficial bugs, there are certain things that you must keep in mind. First of all, if you are thinking of buying or importing exotic species from different parts of the world then you would require a permit as the importing of such species is illegal without a permit. Wouldn’t want you to break the law trying to protect your garden.

The second thing that you need to keep in mind and perhaps the most important thing is that make sure that the species you are getting for your garden can survive in the new environment and vegetation of your home.

Another thing that you should remember is that your garden should have quite a few of the harmful bugs in your garden or else the beneficial insects might leave your garden for a more readily available food source.

Braconid Wasps

The braconid wasp preys mostly on large insects such as caterpillars, hornworms, moths, and some aphids as well. The reason it preys on large insects is linked to its reproduction process.

It lays its eggs inside live and healthy caterpillars, which become the host. Then when the larvae hatch from the eggs, they feed inside the host until they complete their development after which they leave and the host dies.

They are attracted by plants that secrete nectar and small flowers so you might want to plant some Dill, common yarrow, parsley etc. The Braconid wasp is quite a gruesome but sure fire way to get rid of the moths and caterpillars in your garden.

Green Lacewings

The green lacewings will pretty much eat any insect that has a soft body hence why the majority of their diet consists of aphids although they can also eat spider mites, insect eggs, caterpillars and thrips. The green lacewings are quite hungry when they are in development, they have been known to eat over 200 aphids in only a week when in their larvae form.

The lacewing’s larvae will resort to cannibalism if there is insufficient food. Due to this immense hunger most green lacewings tend to lay their eggs near a colony of aphids so that when their eggs hatch, the larvae have a readily available supply of food. The green lacewing can be brought to your garden by growing some dill, angelica, coriander or dandelion.

Ground Beetles

Ground Beetles are great eliminators of insects like slugs, caterpillars, cutworms and snails. These nocturnal insects are a danger to any other insects that can be found in your garden soil. Ground beetles are in no way small although they have less of a hunger than the green lacewing.

A ground beetle larva alone can eat up to 50 caterpillars. Ground Beetles make their home plants like evening primrose, amaranthus and clovers. Due to their nocturnal nature they will only be active at night. So, don’t think that the ground beetles have left if you don’t see them in the day.

Bumblebees don’t get rid of the insects in your garden using the traditional way of hunting; they only kill those that threaten to harm them or their hive. The best thing about introducing the bumblebees into your garden is that they are nature’s best pollinators.

Fungus Gnat Predator

The fungus gnat can be a very dangerous insect for your plants because it feeds on the roots. Often times, they cannot be easily removed. However, the fungus gnat predator is a good solution to this problem.

They prey on the fungus gnat when the pests are in their larvae form.  Fungus gnat predators puncture the larvae and eat what’s inside. This predator inhabits the top layer of the soil and prefers moist conditions.

Wrapping It All Together

It’s a good idea to learn the life-cycles and diets of both the beneficial insects and the pests in your garden. This will prevent you from accidentally ending up destroying the “good guys”.

Before fighting insects with insects, see if there are other natural ways to get rid of the invading pests. One good method is having plants that repel the harmful insects or some other way to get rid of them.

For example, sage can be used to repel cabbage moths and flea beetles. Therefore, it’s not necessary to introduce tachinid flies into your garden. A strong hose spray is usually enough to knock away most of the soft bodied insects.

You may already know that if a vegetable becomes overripe, it becomes a very good attractor for some garden pests. It’s okay to leave earthworms in your garden since they are quite beneficial in the long run. They increase air space in the soil and leave behind worm castings that help the soil.

One thing that you should remember is that introducing natural predators into your garden does not guarantee instant results. Sometimes it might not even change a thing.

Several factors may be involved. The insects you introduced may not suited for the climate of your home. Furthermore, there are other predators present in the vicinity that can devour the beneficial insects.
