What Insects Are The Most Beneficial in Your Garden?

For example, applying pesticides might annihilate all insects irrespective of their advantageous effect on vegetation. Research indicates that a great many recognized insects might actually dwell in your backyard. As such, a majority of these garden insects are either useful or not detrimental.

Some insects are helpful in your garden, while others are pests that destroy your plants. It is beneficial for a gardener to know the type of bugs in the garden and how they affect their crops. With this knowledge, a gardener will decide what kind of treatment to use for their garden.

We will look at INSECTS GOOD FOR GARDEN, how they will likely help your plants and how to attract insects to the garden. But first, let us look at how insects help your plants.

INSECTS GOOD FOR GARDEN help your plants thrive in different ways:

Pollinators: these insects are critical for pollinating your plants. They transfer pollen, facilitating the productivity of your plants, and they include moths, flies, butterflies, and bees.

Predators: These insects feed on other insects and, in the process, eliminate pests from your garden. They include ladybugs, green lacewing larvae, and praying mantes. Introducing these types of insects is the most natural way of controlling pests in your garden.

Parasites: these are different types of predators. They lay their eggs on the harmful bugs, and once their eggs hatch, the larvae feed on the host. The largest group in this category of parasitized is wasps.


This section will look at some of the bugs you might want to encourage in your garden and their benefits.


Ladybugs are some of the most useful insects in your garden. As they develop, ladybugs begin their lifecycle from eggs. These eggs then hatch into larvae. The larvae stage of the lady gub is the most useful to a gardener. These semi-developed insects feed on the most destructive pests, aphids. A single ladybug larva can feed on 4oaphids in one hour.

Green Lacewings

These insects are useful to plants in two ways:

  • Adult green lacewings feed on nectar and pollen, and in the process, they transfer pollen. They also help in the critical process of cross-pollination.
  • These insects also lay their eggs on these plants, hatching them into useful larvae. Their larvae resemble a slug/an alligator and feed on soft-bodied pests such as aphids and caterpillars.

Praying Mantises

The praying mantis is a fierce predator. It preys on grasshoppers and any other insects it comes across in your garden. Also, remember that the mantis will kill useful insects such as butterflies, bees, and other praying mantises as it feeds on harmful insects.


Spiders are small bugs that do not fall under the classification of insects because of their body structure. Spiders are indeed arachnids and help control pests in your garden. They are most useful because they trap live insects, killing them. Unfortunately, you may not encourage them in your garden due to their poisonous bites.

Ground Beetles

The name refers to a group of beetles beneficial to gardeners as larvae and adults. These predatory insects feed on various insects and pests in your garden, including silverfish, slugs, weevils, thrips, caterpillars, and nematodes.

You, however, need to control the population of some of these beetles. Japanese beetles are the common destructive beetles that gnaw away plants and flowers. All in all, ground beetles are good for your garden.

Soldier Beetles

These insects are also predators. They feed on harmful pests in your gardens, such as aphids, caterpillars, Colorado potato beetles, and Mexican bean beetles. These beetles are attracted to your garden by blossoms, and you are least likely to find them in some gardens. For this reason, they also act as pollinators.

Assassin Bugs

These insects resemble a mix of a squash bug and a praying mantis. They have a sharp mouths with which they prey on pests and insects in your garden. These insects and their nymphs are good predators and some of the most useful insects in your garden. However, it would help if you were careful not to mistake them for squash bugs.

Robber Flies

These are some of the most useful predatory insects in your garden. They have long legs and which helps them in predating. Unlike horseflies, robber flies are more welcome in the garden as they are harmless to humans unless threatened. You will also be pleased that robber flies go after a specific type of garden pest.


This insect looks like a yellow jacket and feeds on pollen and nectar.

As a result, they help in pollination, more so where cross-pollination is essential. Additionally, hoverfly larvae are vicious predators feeding harmful pests such as aphids, thrips, beetles, and caterpillars. A hoverfly larva kills insects by sucking the juice from their bodies.

Parasitic Wasps

These are small types of wasps whose activity may be invisible. Despite their size, these insects are very useful in your garden. Let us look at the different types of parasitic wasps and their work.

Braconid wasps; are a group of parasitic wasps that lays eggs on the backs of caterpillars and tomato hornworms. Their eggs form white cocoons on the back of the affected insects. Once the larvae hatch, they feed on the host killing it. The larvae also develop into more wasps that continue caring for these harmful parasites.

Trichogramma wasps; are other parasitic wasps that work similarly to the braconids above. However, they lay eggs on other insects, such as grasshoppers, caterpillars, Mexican bean beetles, and squash bugs. Indeed, this insect is known to take care of over 200 garden pests.

Big Eyed Bug

This is another useful bug that kills harmful insects in your gardens, such as aphids and caterpillars. It attacks and kills these insects when they least expect it and sucks their bodies dry. They are also attracted to cosmos, fennel, mint, marigolds, and goldenrod.

Syrphid flies

You often spot these insects hovering over flowers in your garden like helicopters. Pollination is a major advantage of the syrphid flies in your garden, as they feed on flower nectar.

Additionally, they feed on pests such as aphids, caterpillars, thrids, scales, and mealybugs. Their females also lay eggs on the eggs of other insects, ensuring an abundant food supply for their larvae.

Rough stink bug

These smelling insects are beneficial to your plants. They feed on soft-bodied insects, aphids, beetles, larvae, and caterpillars.


These insects lay eggs near water sources. As their eggs hatch, the larvae feed on the young ones of other flying insects. Their adults are also swift predators killing mosquitoes, gnats, and flies.

Native bee

There are many types of bees, and they all serve a major role in pollination as it sucks nectar from flowers. Bees are aggressive and will bite when threatened.


Adult butterflies are quite useful to your garden as they help facilitate pollination. A butterfly develops through stages whereby an adult lays eggs that develop into a caterpillar, pupa, chrysalis, and then a butterfly. The insect’s host plant provides shelter and food for the developing young one to maturity. Butterflies generally feed on nectar and plant and fruit sap.


These are some of the most useful organisms in your gardens. They are not insects but a different class of organisms that live in the soil. Earthworms help fertilize the soil in the following ways:

  • Break down organic matter in the soils, making them more fertile.
  • They fertilize the soil with their nutritionally rich droppings
  • They increase the amount of air in the soil as they move about. The air is essential for the roots. Additionally, it makes the soils more permeable to water.

How to attract insects to the garden

Insects need basic survival needs, including food, water, and shelter. Consequently, you can invite insects to your garden by catering to these needs.

You can also diversify your garden with flowering plants that attract beneficial insects. A sustainable food supply will help retain the insects in your garden. With a diversified garden, you ensure an unlimited variety of food.

For instance, you can let tiny blossoms bloom, such as parsley, carrot, and alyssum, attracting certain pollinators and predators during spring.

Planting flowering herbs and allowing them to flower is also another alternative. These include parsley, mint, thyme, lavender, dill, fennel, and coriander. Other flowers appealing to good insects include black-eyed Susan, coreopsis, sunflowers, iron flowers, ironweed, goldenrod, and coneflowers.

Another useful solution is through plant companionship as you mix up plants in your garden, plant flowering plants close to vegetables that require protection.

To keep insects in your garden, provide them with a source of water. You can do this by placing a bowl of water insects with water in a shallow dish in your garden. Inside the water, put some stones for the insects to land on.

Reduce the rates of soil disturbance likely to affect organisms residing in the soil and their eggs. Such organisms are critical in enhancing soil fertility; a good example is earthworms.

To attract and retain predatory beetles, create pathways for them to shelter. These can be in the form of mulch and stones. Also, leaving leaf litter on the bed will provide overwintering spots for insects.

You can attract spiders by providing shadowy cover and shelter spots.

To attract earthworms, you must add manure or compost to your garden.

You can also purchase useful insects from a nectary. Those available for purchase include ladybugs, braconid wasps, or lacewings, effectively controlling notorious pests such as aphids. It is important to note when buying predatory insects and releasing them into your garden because the insects you buy are likely to alter the natural ecosystem of your garden.

For this reason, natural methods are more beneficial to gardeners. Also, pesticides will kill all the insects in your garden regardless of whether they are pests or beneficial. This also equally applies to natural pesticides.
