If you are new to gardening or small-scale farming generally, it might seem rational to classify all bugs found in your garden as bad. Even some veteran farmers still have a hard time figuring out which of the bugs on their farms are bad for their plants and which ones are good.
By simple classification, Good garden bugs are the varieties of animals, insects, and other organisms that would help your plants grow directly or indirectly. Therefore, by contrast, bad garden bugs are those animals, insects, or other organisms that can impede the development of your plants directly or indirectly.
This article will help to demystify some of the misconceptions about the garden bug, highlight some of the best ways to recognize the good from the bad bugs and give you tips on balancing your garden bug population.

Houseplants Pests and Bugs: Superb Guide to Identifying and Getting Rid of Different Pests (2021)
Good vs. Bad Garden Bugs; What exactly is the difference?
You need to understand the concept of the direct and indirect impact that a certain garden bug might have on your plants. Praying mantis, for instance, is a carnivorous bug that would eat any insect put in its way, even another praying mantis.
This might be good for controlling the population of some of the bad bugs you might have in your garden. Therefore, the praying mantis in this context is a good bug.

However, if you need lots of bees to help propagate the growth of your flowers in your flower garden, for instance, a praying mantis would be considered a bad garden bug. This is because a praying mantis would prey on the bees in your garden.
With these analogies and making things easy for you, many of the bugs discussed in this article will be generally bad and good garden bugs.
Identifying the Good and Bad Buds in Your Garden
Most humans’ instinct is to squash any bug found on their garden or farm immediately, but that is not quite advisable. It would help if you learned to recognize the good from the bad bugs to control the bug population on your farm or garden effectively.
Out of the 1.5 million known species of insects globally, 97% of them are beneficial to farms and gardens, which means that only about 3% of all known insect species in the world are actually destructive to your garden.
Some of the critical animals and insects you need in your garden include bees, butterflies, moths, beetles, and even flies, as they help to pollinate plants.
Other insects help to eat other insects such as the famous ladybird beetle, and green lacewings.
Here is a simple table of generally accepted good and bad garden bugs.
|Good Bugs||Bad Bugs|
|Bees||Termites and Ants|
|Spined Soldier Bug||Aphids (very bad)|
|Nematode||Worms: Apple worm, Cutworms, Wireworms|
|Ladybug||Bettles: Bean Beetle, Click beetles, Ladybugs with 26 and 28 spots|
|Syrphid fly||Moths: Cabbage moth, Hornworm caterpillars|
|Green lacewing||Amphibians: Cane Toads|
|Earthworm||Insects: Cockroaches, Earwigs, Grasshoppers|
|Praying Mantis (most cases)||Mollusks: Slugs and snails|
|Braconid-Wasp||Butterfly (not the insect itself but the eggs they lay are harmful to plants)|
|Ground beetle||Others: Carrot fly and Slaters|
Please note that these bugs stated in this article are specific to regions like Europe and Northern America. Therefore, some bugs might not be found in your location.
The process of identifying a new or strange insect on your garden
Whenever you discover a new insect or bug in your garden, and you are not sure what it is, here are a few steps to help you identify your visitor:
Observation of the bug in question
Observe the insect closely to see what it is doing on your plant. Then take a close photograph of the new bug. If the bug is eating your plant, then it is likely a bad bug (pest). Also, take note of whether or not the new bug or insect is present in a large number.
A large number of new insects in your garden could also mean that you have an infestation problem.
Identification of the bug
Compare the photograph of the new bug you found to any previous bugs you have killed or exterminated before. You can also check other expert sites for new bugs posted to compare with your new visitors, like the Agricultural Research Service Image Gallery and The Bugwood Insect Images.
If you can confirm that you have an invasive pest on your hands, you need to take steps to prevent the spread.
Controlling the bug problem
The best way to control the spread of a new pest is to use high-quality pest control products. You can easily find one in your local store or order one online from a certified vendor.
Ensure that your pest control product is certified not to kill the good bugs in your garden too.
An Overview of Bad Bugs found in the garden
Here is a general overview of the bad bugs that can be found in your garden. This will help you identify and mitigate against the propagation of these pests in your garden or farm.
Stink Bugs are bad bugs that fortunately have many predators
Stink bugs are considered vicious garden pests that can wreak havoc to plants in your garden. Stink bugs are prey to many predators such as spiders, toads, praying mantis, parasitic wasps, and birds.
Ants may be usually a good insect, but can be a bad bug to plants
Ants can actually be good bugs in some cases, but for simplicity in this article, ants are bad bugs. Ants are considered bad bugs because even though they hunt for aphids, they can leave your plant covered in black spots. Also, they can eventually reduce the lifespan of your plant.
Aphids are rather famous bad bugs for plants
Aphids are quite popular for being nasty bugs for a garden. Aphids love to feed on the tips of the new growth of plants. Aphis attacks plants by sucking the soft green stems, buds, and leaves of plants like roses, citrus, hibiscus, and hydrangea. Aphids are good prey for ants to feed on.
You can easily get rid of aphids by spraying them with a mix of soap and water. Also, hosing down a plant with plain water can also help to control aphids.
Mealybugs and their colonies are seen as bad bugs for plants
Mealybugs usually appear as fluffs of white that then turn to cotton-looking masses on plants overnight. Mealybugs usually gather in large colonies on the stems and leaves of plants that they attack. Mealybugs usually segregate themselves by age. Therefore, mealybugs of different sizes will be seen in packs.
Mealybugs usually suck plant saps and therefore weaken the tissue, which then causes the plant to become spotted, discolored, stunted, and distorted.
When mealybugs congregate in large numbers, they can cause the premature drop of leaves and fruits of a plant. They are also known to attack houseplants and greenhouses usually.
How to control mealybugs infestation
Mealybugs can be controlled by isolating infected plants and wiping off mealybugs with a soft wet sponge, cloth, or soft material dipped in alcohol.
If the plants are outdoors, you can spray the plants with a mixture of water and insecticidal soap.
Squash Bugs thankfully are bad bugs that can be easily repelled in your garden
Squash bugs usually start as small shiny coppery orbs that then hatch into little gray nymphs that mature into squash bugs that destroy plants.
You can easily control Squash Bug by planning marigold around your garden to help repel squash bugs.
Cabbage Worms are rather nasty bad bugs that may be present in your garden
Cabbage worms are quite destructive in nature and are found on the undersides of leaves. Once they start eating, they never really stop eating. They are known for putting holes in kale, cabbage, radish, broccoli, turnip, and cauliflower leaves.
There are two major signs that cabbage worms have infested your plants: the haggard holes in your plants’ leaves and tiny black spots on the leaves on which they excrete.
Chicken and ducks are known to prey on these worms. However, if you have a large infestation, then this might not be an option for you.
The best method for you to try would be to spray citrus oil on the infected plants or sprinkle cornmeal around the plants. These two methods would cause the worms to bloat and eventually die.
Grasshoppers, or at least a select of them, are bad bugs to plants
It is estimated that out of the 600 species of grasshoppers found in the United States, 30 of those species cause serious damage to plants. Therefore, grasshoppers are considered garden pests.
Grasshoppers are chewing insects, and when they infect a farm or a garden in large numbers, they can deal serious damage to a farm or garden.
Crops that grasshoppers often feed on and signs of their damage
Some of the crops that grasshoppers feed on include the following:
Grasshoppers usually feed on the stems and leaves of plants; therefore, the sign of grasshopper damage includes holes in plant and ragged plant edges.
Since grasshoppers are quite mobile, they can be hard to eliminate from your garden, but here are a few tips to get you started.
Best ways to control the grasshopper population in your garden
We will be talking about ways to combat the growing population of grasshoppers in your garden by doing some extra gardening work and tasks, using household items to keep them at bay, and even calling on to predators of this insect.
Doing extra gardening work to eliminate grasshopper infestation
Female grasshoppers lay their eggs in the soil, leaving the eggs to overwinter in the soil before hatching in the spring.
Till your soil in mid-to-late summer to prevent the grasshoppers from laying any eggs, then till your soil in late fall to early spring to destroy any egg laid during the previous summer.
Another way to combat the infestation is by hitting 2 birds with one stone for your garden. Strive to remove the weeds around your garden. This act will effectively eliminate any alternative food source that grasshoppers might have.
Using household items to keep grasshoppers at bay
You can either cover up the plant itself with cheesecloth or crop cover, which is a direct way to keep these insects from eating your plant.
But, you can also look into making a garlic spray because this solution is sure to prevent grasshoppers from feeding on your plants. To prepare a garlic spray, mix two cups of garlic with ten cups of water, boil it, and cool overnight.
Mix the boiled solution of garlic and water with 3 parts water in a spray bottle. This solution would also repel other plant-eating insects.
Fostering Chickens and maybe even Predators of grasshoppers to keep them at bay
Introduce some of the natural predators of grasshoppers to help eliminate any existing population of grasshoppers in your garden. Some of those predators include birds like a swallow, praying mantis, and toads.
However, if you are also looking into getting into the poultry business, now is the perfect time to care for you, then chickens in your garden, and they will help eat your grasshoppers. However, it would be best to be careful not to plant crops that chickens can feed on.

Good hired assassins’ for bad bugs
Depending on your area, of course, there may be ways to attract the likes of bats and birds. These animals are well known for gobbling up bad bugs. More common good hired assassins that you can look into, though, would be centipedes, dragonflies, and frogs.
However, again, everything is best in moderation. Take care to attract these animals and insects moderately and not cause more problems for your garden.
Overview of Good Bugs found in the garden
With all this negativity on bad bugs and their characteristics, let us shift to brighter things like good bugs in the garden. These bugs are definitely the ones you should look into attracting into your garden to flourish and be healthier.

Ladybugs are so beneficial to the control of aphids in gardens that they are grown and sold commercially to garden owners and greenhouses.
Lacewings are great good bugs to keep aphids at bay
Lacewings are also very beneficial to gardens for a lot of reasons. First, the adult lacewing feeds on pollen and honeydew at night, and therefore, aid in pollination. However, the larvae of lacewings feed on aphids, mealybugs, whitefly, mites, thrip eggs, and scale.
Lacewings are also considered an effective means of controlling aphids’ population in a garden sold commercially.
Bees are definite good bugs
Bees are generally considered beneficial to the garden because they help with pollination and never really bother any other insects on the farm or garden.
Regardless of the type of bee, you find in your garden, honey bees, mason bees, and bumblebees all help with pollinating flowers and trees.
Ground Beetles/ Bombardier Beetles are good bugs that help in eliminating other pests
Ground and Bombardier beetles are very beneficial to the garden’s ecology as they help eliminate many garden pests. Some of the prey of these beetles include larvae and adult caterpillars, cutworms, march flies, slugs, thrips, snails, aphids, ants, termites, grasshopper eggs.
Hoverflies are god bugs that attack pests
Hoverflies are one of the critical, good bugs to have in your garden because of how well they attack pests. Hoverflies usually feed on aphids, beetles, and caterpillars.
They actually lay their eggs in aphids, which means that their offspring will always have food to eat.
One essential feature of hoverflies is their ability to help pollinate plants since they also feed on nectar and pollen grains.
Several other good bugs can be found in your garden, and usually, the rule of thumb is that slow-moving insects are usually bad for your garden, while fast-moving ones are usually good.

If, however, your garden is close to a pond, you will likely have frogs in your garden. Frogs are very efficient hired assassins for gardens. Some of their prey include moths, flies, grasshoppers, cockroaches.
Birds consume a large number of bugs and can help a lot with controlling destructive insects. Just make sure that your garden does not contain fruit trees that birds can prey on too.
Here are some birds and the insects they feed on:
|Type of birds||What they feed on|
|Swallows||Beetles, grasshoppers, moths|
|Woodpeckers||beetles, weevils, borers, larvae|
|Sparrows||Caterpillars, cutworms, beetles|
|Bluebirds||Crickets, larvae, moths, grasshoppers|
|Oriole||Caterpillars, beetles, grasshoppers, larvae|
