How to Use Beneficial Insects to Keep Your Garden Healthy

Keep Your Garden Healthy

By using beneficial insects, gardeners can effectively control pests and diseases without relying on harmful chemicals. This approach not only supports the health of the garden, but also promotes biodiversity and environmental sustainability. 

To use beneficial insects, simply introduce the insects into the garden and provide them with food, water, and shelter. Common beneficial bugs that keep other pests away include ladybugs, lacewings, and assassin bugs. With proper management, these insects can effectively control pests, improve soil health, and enhance the overall beauty of your garden.


Ladybugs can be helpful in keeping your garden free from pests. They’re especially good at dealing with aphids, which tend to be a major problem for vegetable gardens and rose bushes. 

To keep ladybugs happy and thriving in your yard, it’s important to give them what they want. This includes food, water and shelter. 

One way to attract ladybugs is to put out a plethora of flowers. Ladybugs like to eat aphids. But it’s not enough to just throw some flowers out. You need to choose plants with a long bloom time. Some of these include sweet alyssum, parsley, yarrow, and evening primrose.

When you release your ladybugs, it’s a good idea to make sure that they get the water they need. Ladybugs can drink dew from the ground, but they also need moisture from insects they eat. For this reason, it’s best to sprinkle them with a few misted leaves or water.

It’s also a good idea to protect your ladybugs from predators. You can do this by planting low ground cover plants or mulching around them.


Lacewings are a type of beneficial insect. These predators are very efficient at consuming harmful garden pests. They can be a very helpful way to control aphids and scale bugs in your garden.

They are natural predators of many garden pests, including aphids, mites, caterpillars, and more. Lacewings lay their eggs on thin stalks near a food source, and when the larvae hatch, they feed on the pests. 

Lacewings are also beneficial pollinators and help to improve soil health by breaking down organic matter. To attract lacewings to your garden, provide a source of nectar and pollen for adult lacewings and create a habitat that provides protection from the elements and predators. 


Spiders feed on insects, including small flies and beetles, as well as other arthropods like mites and aphids. By reducing the population of these pests, spiders help protect your plants from damage. 

Spiders can also act as a natural form of pest control, as they compete with other insects for food and space.

Another way spiders can benefit your garden is by pollinating flowers. While they don’t do so directly, spiders are responsible for carrying pollen from one flower to another while hunting prey or looking for a mate. This helps the plants reproduce, allowing more flowers to grow in your garden.

And also, spiders help to improve the soil in your garden. As they hunt and feed, their webs catch bits of plant material that slowly break down and add organic matter to the soil. This helps improve soil structure, making it easier for your plants to take up nutrients and water.

Ground Beetles

Ground beetles are beneficial insects that can help protect your garden from pests. They feed on a variety of soft-bodied insects such as aphids, caterpillars, slugs and snails. 

They also eat other small invertebrates like spiders and millipedes. Having ground beetles in your garden helps to keep the population of destructive pests in check, reducing the need for chemical pesticides.

Ground beetles are active at night and hide during the day. They can be found under rocks, logs, plant debris and even in leaf litter. The adults lay their eggs near potential food sources like aphids or other pests, so if you have an abundance of these insects on your plants, you may have a ground beetle infestation.

They are beneficial because they provide natural pest control. By eating insect pests that would otherwise damage your plants, they help reduce the need for chemical pesticides. 

Praying Mantis

There are many ways to attract praying mantis to your garden. You can give them food and water, and make sure they have a place to hide.

They can be a fun and interesting insect to watch. But they can also be a nuisance if you have too many. Thankfully, you can control their numbers and stop the spread of this invasive species.

Find an area with plenty of plant life. This can be a garden, a shrubbery, or a fence. Praying mantises are drawn to tall grasses and plants in the rose family.

You can buy a praying mantis egg case. These are available from garden supply stores, as well as online beneficial insects companies. Look for the ones with perforated lids so they can breathe.

When the time comes, you can release the praying mantis into the wild. You can attach it to a twig or a tree branch. Do not use a sharp object.

You can even feed the praying mantis trapped insects. Just be sure to remove any dead bugs. It isn’t recommended to pet them, though.


Hoverflies can be a great addition to your garden or outdoor space. They feed on nectar and pollen from flowers, which helps support pollination of other plants. This is especially beneficial in areas with fewer pollinators due to habitat destruction or pesticide use. 

Their larvae feed on aphids, which can provide natural pest control and prevent the need for chemical treatments. Hoverflies also help reduce fungal diseases by consuming spores on the surface of leaves.

Hoverfly populations can be encouraged in your garden by creating the right environment. Plant native wildflowers that bloom throughout the year, as this will provide nectar and pollen sources for hoverflies throughout their lifecycle. 

Assassin Bugs

Assassin Bugs are predatory insects that are native to North America and they are members of the Reduviidae family. 

There are over 3,000 species worldwide. Most are brown, black or gray. Some have sticky hairs.They are commonly found in flower beds and orchards. These indiscriminate killers eat almost anything, from caterpillars to leafhoppers. But they can also be dangerous to humans.

When assassin bugs bite, they inject venom and digestive juices into the victim’s body. This can lead to swelling and even death. The bugs are also known to be able to pierce skin with their sharp beak.

Although many people are afraid of insects, they can be helpful in your garden – they are beneficial in combating aphids. If you find that your garden is infested by aphids, you can spray chemicals or use soaps to kill them. If you do not want to use chemicals, you can also attract assassin bugs with foods like dill and marigolds.

Adult assassin bugs range from half an inch to one and a half inches. They can fly, but they are generally poor fliers.

Assassin Bugs are good for your garden because they eat many of the pests that damage your plants. In addition to killing pests, they can also be helpful in controlling some beneficial insects.


Beneficial insects are a great way to keep your garden healthy. With their natural instincts and appetites for pests, they can help keep destructive bugs away and reduce the need for chemical pesticides. 

Not only do these helpful critters provide natural pest control, but they also promote healthier soil and encourage pollination of plants. So if you’re looking for a more sustainable and effective way to keep your garden healthy, consider introducing beneficial insects.
