How to Get Rid of Aphids in the Garden

Gardening is a beloved pastime for many New Zealanders, offering a chance to connect with nature and cultivate beautiful, thriving plants. However, every gardener knows that pests can quickly turn a lush garden into a battleground. Among the most common and frustrating pests are aphids. 

These tiny insects may seem harmless at first glance, but they can cause significant damage to both residential and commercial gardens. In this Jim’s Mowing NZ blog, we’ll explore what aphids are, the different types you might encounter, the damage they can cause, and most importantly, how to get rid of them. 

What are Aphids?

Aphids are small, soft-bodied insects that belong to the superfamily Aphidoidea. They are commonly found in gardens and are known for their ability to reproduce rapidly. Aphids are typically green, but they can also be black, brown, yellow, or even pink. They are usually about 1-3 mm in length and have pear-shaped bodies with long antennae.

 

These pests are sap-suckers, meaning they feed on the sap of plants by piercing the plant tissue with their needle-like mouthparts. This feeding behaviour can weaken plants, stunt their growth, and even transmit plant viruses. Aphids are often found on the undersides of leaves, where they can go unnoticed until their numbers have exploded.

Different Types of Aphids

There are over 4,000 species of aphids worldwide, and while they all share some common characteristics, there are several types that are particularly common in New Zealand gardens. Here are a few you might encounter:

  1. Green Peach Aphid (Myzus persicae) – As the name suggests, these aphids are usually green and are commonly found on peach trees, but they can infest a wide range of plants, including vegetables like potatoes and tomatoes.
  2. Black Bean Aphid (Aphis fabae) – These aphids are black and often found on broad beans, but they can also infest other legumes, as well as ornamental plants like nasturtiums.
  3. Rose Aphid (Macrosiphum rosae) – These aphids are typically green or pink and are commonly found on roses, as well as other ornamental plants.
  4. Woolly Apple Aphid (Eriosoma lanigerum) – These aphids are covered in a white, waxy substance that gives them a woolly appearance. They are commonly found on apple trees and can cause significant damage to the fruit.
  5. Cabbage Aphid (Brevicoryne brassicae) – These aphids are grey-green and are commonly found on cabbage, broccoli, and other brassicas.

Damages Caused by Aphids to Any Garden

Aphids may be small, but the damage they can cause to your garden is anything but insignificant. Here are some of the most common problems associated with aphid infestations:

1. Stunted Growth

Aphids feed on plant sap, which can weaken the plant and stunt its growth. This is particularly problematic for young plants, which may struggle to recover from the damage.

2. Yellowing Leaves

As aphids suck the sap from leaves, the leaves may turn yellow and eventually die. This not only affects the plant’s appearance but also its ability to photosynthesise and produce energy.

3. Honeydew and Sooty Mould

Aphids excrete a sticky substance called honeydew, which can attract other pests like ants. The honeydew can also lead to the growth of sooty mould, a black fungus that can cover leaves and further inhibit photosynthesis.

4. Transmission of Plant Viruses

Aphids are known vectors for several plant viruses, which they can transmit as they feed. These viruses can cause a range of symptoms, from leaf curling to complete plant death.

5. Deformed Flowers and Fruits

Aphids can cause flowers and fruits to become deformed, reducing their aesthetic appeal and making them unsuitable for consumption.

How to Get Rid of Aphids

Fortunately, there are several methods for controlling and eliminating aphids in your garden. These methods can be broadly categorised into natural and chemical approaches. Let’s explore both in detail.

Natural Ways to Get Rid of Aphids

 

Homemade Pesticides

  • Soap and Water Spray

One of the simplest and most effective natural remedies is a soap and water spray. Mix a few drops of mild liquid soap with water in a spray bottle and apply it directly to the aphids. The soap breaks down the aphids’ protective outer layer, causing them to dehydrate and die.

  • Neem Oil

Neem oil is a natural pesticide derived from the neem tree. It works by disrupting the aphids’ hormonal balance, preventing them from feeding and reproducing. Mix neem oil with water and a few drops of liquid soap, then spray it on the affected plants.

  • Garlic Spray

Garlic has natural insect-repellent properties. To make a garlic spray, blend a few cloves of garlic with water, strain the mixture, and then spray it on the plants. The strong smell will deter aphids from settling on your plants.

Natural Aphid Predators

  • Ladybugs

Ladybugs are natural predators of aphids and can consume large numbers of them in a short period. You can attract ladybugs to your garden by planting flowers like marigolds and daisies, or you can purchase them from a garden centre and release them into your garden.

  • Lacewings

Lacewing larvae are also voracious aphid predators. Like ladybugs, you can attract lacewings to your garden by planting a variety of flowers or purchase them for release.

  • Parasitic Wasps

These tiny wasps lay their eggs inside aphids, which eventually kills them. While you can’t easily purchase parasitic wasps, you can attract them by planting a diverse range of plants in your garden.

Physical Removal

 

  • Hose Them Off

A strong blast of water from a garden hose can dislodge aphids from your plants. This method is particularly effective for small infestations and can be repeated as needed.

  • Pruning

If you notice a heavily infested branch or leaf, prune it off and dispose of it properly to prevent the aphids from spreading to other parts of the plant.

Chemical Ways to Get Rid of Aphids

While natural methods are often preferred for their environmental friendliness, there are times when chemical treatments may be necessary, especially for severe infestations. Here are some options:

1. Insecticidal Soaps

These are commercially available soaps specifically formulated to kill aphids and other soft-bodied insects. They work in a similar way to homemade soap sprays but are often more effective.

2. Systemic Insecticides

Systemic insecticides are absorbed by the plant and kill aphids when they feed on the sap. These treatments can be very effective but should be used with caution, as they can also harm beneficial insects.

3. Contact Insecticides

These insecticides kill aphids on contact and can provide quick results. However, they may also kill beneficial insects, so they should be used sparingly and only when necessary.

4. Professional Treatments

If you’re dealing with a severe or persistent aphid problem, it may be time to call in the professionals. Jim’s Mowing NZ offers expert gardening services, including pest control, to help you get rid of aphids and keep your garden healthy. Their team of experienced gardeners can assess your situation and recommend the best course of action, whether it’s natural or chemical treatments.

In Summary

Aphids may be small, but they can cause significant damage to your garden if left unchecked. Understanding what aphids are, the different types you might encounter, and the damage they can cause is the first step in managing an infestation. Fortunately, there are several methods for getting rid of aphids, from natural remedies like homemade pesticides and natural predators to chemical treatments and professional services.

Rats Love Yard Rubbish: Tips To Keep Them Away

/in , /by

Rats are disease carriers. They eat almost everything. Also, they can make themselves at home in sheds, garages, houses, and gardens. They cause unpleasant damage and odours to possessions and property.

3 Main Rat Species in Australia

  1. Roof Rat – Also known as ship rat and black rat, the roof rat has a slender body. Its tail is as long as its head and body combined.
  2. Norway Rat – This is also known as wharf rat, sewer rat and brown rat. This is bigger than the roof rat and is found wherever humans reside. It has a small, close set of ears that don’t reach the eyes when pulled down. An adult Norway rat weighs about 500g.
  3. House Mouse – This has a slightly pointed nose, large scantily haired ears, black protruding eyes, and hairless tail with very obvious scale rings.

Why Worry About Rats?

Rats can carry diseases like typhus fever and leptospirosis. They also carry ticks and fleas that can harm pets and humans. They contaminate food with their droppings, urine and hair that can lead to food spoilage and poisoning. Lastly, they generate unpleasant odours and damage materials like wood, wiring, insulation, and food containers.

8 Tips to Keep Rats Away From Your Garden

  1. All rubbish must be kept in sealed containers.
  2. Clear out sheds or storage areas regularly. You must remove the things you no longer use.
  3. Stack bricks and firewood above the ground – preferably at least 30cm from the ground.
  4. Collect and properly dispose of any fallen fruit.
  5. Keep your grass mown and free from any debris.
  6. Give your pets only what they will eat in a day.
  7. Store all left-overs in sealed vermin-proof containers.
  8. Look around your house and cover or repair any holes or cracks in your property.

How to Get Rid of Rats

Use live rodent traps – These are among the most popular and effective ways of managing rats in your garden. Make sure that the traps are checked every day to remove, relocate or humanely destroy the trapped rats.

Use rat baits and poisons – These are short-term solutions. Rats eat baits and poisoned foods and then go away to die. Using poisons, however, has disadvantages. Pets and children may ingest mislaid baits.

Use snap traps – These traps are a humane and fast way of controlling rats. You can buy them at hardware and grocery stores. They can be set with cheese, meat, bread, fish or chocolate. Since these traps can be messy, consider asking someone to dispose of the victim of such traps when you have a weak stomach.

Deal with your rubbish properly to prevent rats from invading your property. Get help from rubbish removal experts if you must.

Aphids

Various pests can easily invade a garden. Without the right pest control strategies and their immediate implementation, you will end up having a yard that is home not just to your plants, but to several insects as well that can cause your foliage to wilt and die.

Here are some natural pest control products and solutions for your garden that you can easily make at home:

For Aphids

To make a natural insecticide that will help you deal with aphids, you need to have 1 cup chewing tobacco juice first. You can make this by placing three

Scale

pieces of chewing tobacco in an old nylon stocking and soak this in a gallon of hot water. Once the mixture turns dark brown, run it through a sifter to remove the particles from the juice.

Mix the tobacco juice with 1 cup of liquid dish soap and 1 cup antiseptic mouthwash. Pour the mixture into a 20-gallon sprayer and fill the rest of the container with water. To get rid of aphids and keep them away, spray the mixture on vegetables and plants every other week.

For Scale

Scale insects suck sap from leaves, stalks, and stems. If you allow these pests to live on your plants, they will cause the death of the stems.

Shield Bug

To get rid of scale, mix 1 tablespoon of ground mustard seeds and add 20 parts of water. Mix well, put in a sprayer, and drench the affected plant.

For Shield Bugs and different types of leaf-eating Insects

Nobody wants to have plants with leaves that are slowly being devoured by insects. To effectively deal with leaf-eating insects, hard-surfaced pests, and even scale, chop 4 bird’s eye chillies (or other really hot types of chillies), 2 bulbs of garlic, and 4 large onions. Combine all of these in a container with 2 litres soapy water. Allow the mixture to steep for at least 24 hours. Strain the mixture and dilute with water, if necessary, then pour it into a sprayer. Spray the affected plants. You can store the remaining mixture in a sealed container and keep it in a dark place but make sure to use the leftover product within 2 weeks.

Ants

For Ants

To get rid of these pesky insects, put 10 to 15 drops of peppermint essential oil in a spray bottle with water. Spray the area where ants usually are – they won’t come back since they hate the smell. If you have cats, make sure they don’t go to the sprayed area since this product can be harmful to them.

For Caterpillars and other sucking Insects

Caterpillars, mealy bugs, and slaters are just some of the sucking insects that can inflict a lot of damage to your garden.

Caterpillar

For a homemade natural insecticide that targets these pests, combine 90g of chopped garlic cloves and 2 tablespoons of mineral oil or liquid paraffin and let it steep for at least 48 hours. When ready, dissolve 15g of pure soap or soap flakes in a container with 500ml warm water. Mix the 2 solutions together and strain. To use, add 1 part mixture to 50 parts water and spray on the affected plants.

With some common products in your home and a bit of ingenuity, you can have a pest-free garden. For more garden and landscaping tips, tune in for more Jim’s Mowing NZ blogs.

Natural Homemade Pest Control Recipes

/in , /by

Pests are among the most unwanted and most harmful insects and animals that home owners and gardeners have to deal with. They do not only destroy plants and damage properties, but they also bring diseases.

To control their growth and minimise their destruction, there is a need to observe pest control measures. Depending on the type of pest and the extent of the damage done, you can either handle pest control yourself or call on experts to help manage and eliminate the pest.

There are different pest control methods and products available in the market today. However, if you are dealing with pests yourself, it is always best to use safe and natural pest control solutions. Natural homemade pest control recipes are safe for both people and the environment. Plus, they are easy on the pocket!

Common Homemade Pest Control Solutions

1. Garlic

Garlic is known for its antibacterial, antiviral, and anti-fungal properties. It is effective for keeping small sucking insects such as aphids and caterpillars at bay.

You will need:

  • 1 head of garlic
  • 1 tablespoon dish soap (without bleach)
  • 2 tablespoons of vegetable oil
  • 2 cups of water

Combine the crushed garlic with the oil, dish-washing soap, and water. Allow to sit overnight, then strain the mixture. Spray on plants.

2. Bicarbonate of Soda or Baking Soda

Fungus occurs as a result of humidity, not enough spacing between plants, and excessive rain. To treat fungal problems in your garden, use a fungicide spray.

You will need:

  • 2 tablespoons of bicarbonate of soda
  • 1 tablespoon of vegetable oil
  • 1 teaspoon of dish soap (without bleach)
  • 2 litres of water

Mix the ingredients thoroughly and spray on plants.

3. Onion, Garlic, and Chili

In addition to garlic, onion and chilies are also considered staple ingredients when making an effective all-around pest control solution for insects and bugs.

You will need:

  • 4 large onions
  • 2 cloves of garlic
  • 4 hot chilies/peppers (the hotter, the better)
  • 2 tablespoon dish soap (without bleach)
  • 2 cups water

Crush or puree the chilies, onions, and garlic. Mix with water and dish-washing soap and let it sit overnight. Strain and add 5 litres of water. Spray on plants.

When using natural home-made pesticides, it is important to keep in mind not to use bleach-based soaps or detergents because bleach is considered harmful to plants. It is also advisable to test out the home-made mixture on a small area of the plant first to make sure it would not cause more damage.

Top 3 Autumn Garden Pests

/in , , /by

Autumn, the season between summer and winter, is the time of the year when the leaves change colour. The sun’s heat mellows down and the days become more soothing. It is considered one of the most enjoyable times to engage in gardening.

Autumn is an excellent time for planting fast-growing herbs and plants, fertilising, pruning, and aerating. However, it is also the time of the year when pests become troublesome. While there are insects and animals that are beneficial to the garden, there are also some that are quite destructive. Control and eradication measures are necessary to keep your garden and plants healthy.

Some of the most common autumn garden pests are:

1. Aphids

With more than 4,000 species, these pests come in white, yellow, green brown, black, and pink colours. You can identify these critters through their pear-shaped bodies, a pair of abdominal tubes, and long antennae. The most prevalent species in Australia are the cotton aphid and the cabbage aphid. They attack fruits, vegetables, and ornamentals by sucking the sap from the plant’s vessels.

How to identify an aphid infestation

  • Unusual leaf drop or stunted growth
  • Curled yellowing or browning leaves
  • Presence of ants because of a sticky substance called “honeydew”
  • Presence of black spots, also known as sooty mold

Control Measures

  • For a minor infestation, you can prune the affected area and spray with homemade garlic spray or systemic insecticide.
  • For a severe infestation, the use of a more potent insecticide is needed — usually, sprays with horticultural oil or insecticidal soap are effective.

2. Snails and Slugs

  • Garden snails and slugs are a huge threat to garden plants. They attack seedlings, leaves, and fruits. The most common among their species are the brown snail and the grey field slug. They avoid the sun and are most active during the night. They thrive well in moist places.

How to identify a snail or slug infestation

  • Shiny silver trails on plants
  • Big holes on leaves

Control Measures

  • Use homemade organic sprays made of garlic and wormwood.
  • Create a snail bait with the use of beer.
  • Place copper tape around pots and garden beds.

3. Caterpillars

The cabbage moth and the cabbage white butterfly lay caterpillars that are harmful to cabbages, broccoli, and cauliflowers. They feed on the leaves or fruits of these vegetables.

How to identify a caterpillar infestation

  • Large holes on the outer leaves
  • Discolouration of the head of cauliflowers and broccoli

Control Measures

  • Use a vegetable mesh around your plants.
  • Pick the caterpillars and squash them.
  • Plant herbs with a strong smell such as basil, coriander, and sage.

Most Common Garden Pests In Winter

/in , , /by

There are plenty of insects that can infest your garden in winter; some are beneficial while some are destructive. Luckily, you can get rid of them with simple solutions. Here is a list of
common garden pests in Australia and how you can get rid of them:

Aphids

The cotton aphid and the cabbage aphid are two widespread species in Australia. Aphids feed on vegetables, fruits and ornamentals by sucking the fluid of phloem vessels. They can easily and rapidly reproduce. To get rid of them, you can use systemic insecticides or garlic spray.

Snails and Slugs

These pests can pose a huge threat to your garden. They can damage leaves, underground tubers, fruit, and plant seeds, and this can lead to major production losses. Snails thrive most in a moist environment.

To control snails, there are many different techniques you can implement. First, you can make a DIY snail trap using beer. Second, assault them at night using a torch and gumboots. Third, handpick and drop them in a bucket filled with salty or soapy water. Lastly, spray them with copper oxychloride.

 

Caterpillars

Small caterpillars love vegetables like broccoli and cabbages. Get rid of them by hand as this is the most efficient way to do so. Also, you can dust with derris dust. Similar to aphids, caterpillars can be deterred through the use of garlic sprays.

Bronze Orange Bugs (Stink Bugs)

Stink bugs can typically be found in New South Wales and Queensland. They are considered a pest to all citrus trees. They appear in late winter as lime green nymphs, but as they grow, they turn into an orange to bronze colour. When controlling these pests, you must be very careful since they emit a foul-smelling liquid that burns the eyes and skin on contact.

As such, you need to use protective glasses, and wear clothes with long sleeves, a pair of gloves, and a hat. You can use a vacuum cleaner to suck them up. Use planks of wood to crush them. You can also pick them up using tongs and drown them into a bucket with soapy water.

Tips for Preventing Plant Diseases in Winter

  • Perform supplementary hand watering in the morning to allow the leaves to dry during the day.
    Handpick mummified fruit from under fruit trees or on their branches. Place them in the rubbish.
  • Watch your clivia since the winter cold may cause fungal problems that can rot the neck of the bulb. As soon as you notice any brown blistered patches on the leaves, spray it with anti-rot.
  • When leaves fall from prunus trees, immediately control shot hole which may disfigure the leaves with a copper oxychloride spray.

Heavy dew can be caused by cooler nights and winter rains. Gardeners may think that they won’t have to spend time and money watering at this time; unfortunately, the moisture can promote bacterial and fungal disease in your garden, so keep this in mind.

Good vs Bad Garden Pests

/in , /by

There are many kinds of plant pests. Insects, mites, birds, and animals sometimes eat plants before farmers or gardeners can even harvest them. Plant diseases can cause crops to suddenly die, or cause the crop rot before it can reach the market.

However, not all pests are harmful to plants. Some are also helpful to your garden and the environment. If you are a garden owner, it is equally important to know which pest is good and which one is bad for your property. This way, you know which ones to eradicate and which ones to allow to wander around your lawn.

Bees, for example, are a familiar sight; they buzz about seeking the rich stores of nectar and pollen held within the flower blossoms. While they may be noisy and “stingy” to be around, many plants would not grow without their help. They are very useful in plant reproduction. As they fly about searching for food, they fertilise plants by spreading pollen from one plant to another. This allows the plants to reproduce.

Another familiar insect you should allow in your garden are the beetles. The ladybugs or the ladybird (also called lady beetle) are great protectors of your green and colourful property. Why? It’s mainly because they feed on common garden and household pests such as mites and aphids. With their presence, you can be sure that no mites or aphids survive because ladybugs eat them, including their eggs.

Other beneficial species of beetles you should invite into your garden are the ground beetles and soldier beetles. These beetles guard your garden from slugs, snails, aphids, caterpillars, and many other insects.

Ants are another kind of garden pest. Are they good or bad for your garden?

For starters, ants serve several valuable functions. They help maintain the balance of nature by consuming a large number of insects and serving as a food source for other animals. They enrich the soil as they dig their burrows, loosening and mixing the dirt. The fungus-grower ants that nest in large chambers deep in the soil are great helpers for composting. They grow fungus on beds of compost made from the
droppings of plant-eating insects such as caterpillars. While they drink some of the plant juice from these materials, they use most of it to raise the fungus that they and their larvae dine on.

Ants also benefit people when they feed on insect pests. In fact, ants were used as the first method of biological pest control more than 2,000 years ago in southern China. The silk nests of green tree ants were moved from nearby forests to orange groves. And since these ants are aggressive predators, they eat any and every insect that crosses their path, thereby helping keep the groves free of pests.

Garden pests have both good and bad sides. Some of the very habits that make them helpful also make them harmful. They can be household pests, infesting food and sometimes delivering painful stings. Some can damage homes and other buildings by burrowing into wood. Learn to control them to keep them from getting inside your home and allowing them only around your garden.

Common Summer Garden Pests

/in , /by

In summer, most pests proliferate. Flying and crawling insects and mice and rats cause tremendous damage every year throughout the world.

In Australia, the summer months can be greatly enjoyable when you’re spending time outdoors. At the same time, they can also be disturbing due to the proliferation of many garden pests such as mosquitoes, flies, fleas, ants, and even rats and possums.

1. Mosquitoes

Mosquitoes were once considered just annoying pests. Now, they are known for causing and spreading diseases that can even be fatal if left untreated by medical experts. Many mosquitoes come buzzing around in spring and mostly in the summer months because their eggs hatch and come out of hibernation during this season.

Controlling mosquitoes:

To make sure you enjoy the summer without these unwanted visitors, you have to keep all surfaces dry because their eggs hatch only on moist surfaces. Remove any stagnant or still, fresh water so they won’t have a place to lay their eggs. If you have a swimming pool or are living near swamps, take note that these are favourite breeding areas. Be sure to contact your town’s agents who are equipped to deal with pest control on a larger scale.

2. Flies

Flies, like mosquitoes, breed in damp places. They hatch in stagnant water, dirty garbage pails, animal refuse, overripe fruits, spoiled vegetables, and even piles of wet cut grass. They multiply quickly and become full grown within 10 days. One fly can produce 120 to 160 eggs at a time and these hatch into maggots within just a day. As such, never allow flies to survive in your property. Do not allow them to fly and crawl around your home because they are also known carriers of serious diseases like cholera, dysentery, and tuberculosis.

Controlling flies:

Remove all possible breeding areas. Clean and tightly cover all garbage bins. Dispose of grass clippings immediately.

3. Fleas

Fleas are also common in summer. These wingless insects are very tiny which make them hard to detect until they have multiplied enough to be seen and felt. These pests are not only annoying to your pets, but also to your entire household.

Controlling fleas:

While a professional pest control operator will have no difficulty getting rid of them, you can also prevent fleas from coming into your home on your own by keeping your pet and your yard clean regularly. Clean all areas where fleas could possibly leap onto hosts, like the lawn while you are mowing grass and trimming bushes.

4. Ants

Ants love living in warmer regions, but they are extremely adaptable and can live in any climate. They are likely to enter your house through any tiny opening, especially the slits under doors, in window sills, and around pipes leading into the house. Some ants live in the walls of houses. Once inside, ants will eat almost anything. There are certain ants that eat mostly sweets, while others prefer grease and fats.

Controlling ants:

Ants are untiring workers. They move in a constant stream to and from a food supply. The best way to eradicate them from your house is to follow their trail, locate their nest or anthill, and destroy it.

If you are not sure about the cause of any of these pest problems, or if the problem seems too difficult to handle, it is best to consult a competent pest-control operator near you. Also, avoid using homemade mixtures or any sprays without an expert’s recommendations as this may do more harm than good.

Beneficial Garden Pests

/in , /by

Often, they are known for their destructive nature, but did you know that some garden insects are also considered beneficial? Some homeowners and gardeners are unaware of the benefits these insects and animals bring.

For starters, these bugs and insects prey on the bad critters that destroy your plants and garden. They are also a natural and cost-efficient solution to your pest infestation problems. Some of the good bugs you should invite in your garden are:

  1. Lacewings

Both the lacewing and its larvae work hard and fast as they prey on bugs, aphids, mites, moths, and caterpillars. To attract them and help them stay around, grow flowering plants and herbs such as coriander, dill, and fennel.

  1. Parasitic Wasps

Parasitic wasps are a variety of tiny wasps that do not sting. They spend their entire life being parasites and end up killing their host. Parasitic wasps help control pests by invading the eggs of their host and laying their eggs on the bodies of insect pests like caterpillars, aphids, whitefly, and mealybugs.

To attract parasitic wasps in your garden and help them grow, it is good to have flowering plants such as marigold, thyme, alyssum, and cosmos.

  1. Ladybirds or Ladybugs

There are over 500 species of Ladybirds found in Australia. Both the young larvae and adults eat pests. However, the larvae feed more than the adult does, doing more damage to garden pests. They eat aphids, mites and mealybugs.

Plant goldenrods, asters, marigold, and fennels to attract them. Feed them well and they will not leave you.

  1. Hoverflies

Hoverflies, also known as flower flies, feed on aphids and most soft-bodied pests. They look like little bees and hatch eggs. Their larvae gobble up aphid colonies and mealybugs. Plant thyme, lemon balm, alyssum, cosmos, and spearmint to attract them and maintain them in your garden.

  1. Tachinid flies

Tachinid flies are commonly known as parasites of caterpillars, bugs, moths, grasshoppers, and earwigs. They lay their eggs near or in the host; the larvae then burrow their way into the body of the host, sucking its bodily fluids and eventually killing the host. The adult Tachinid flies feed on nectar and pollen. Plant thyme, asters, and parsley to attract these flies into your garden.

Inviting and cultivating beneficial insects in your garden will help eliminate pest infestation. It will also give your garden an array of colours since you can plant different herbs and flowering plants that attract beneficial garden insects.
