Insects are essential to a well-functioning garden ecosystem. They play as important a role as animals in a forest ecosystem, so it is important to be aware of the good and bad insects in your garden soil and plants. Although some can be a nuisance, most insects play an important role in your garden, so here’s our guide on the good and bad ones to watch out for. This article covers information about the roles of various insects like ladybugs, praying mantis, grasshopper, grubs, slugs, and ants.
Are Ladybugs Good for the Garden?
Ladybugs are an important part of the garden ecosystem. They help control other insects that can damage your plants, like aphids and scale. Ladybugs will also feed on the eggs of these pests, making them even more beneficial to have around. Ladybugs are a great addition to any garden because they naturally eat many damaging pests.
Here are reasons why ladybugs make good garden companions:
- They eat pests like aphids, mealybugs, and mites: Ladybugs feed on harmful insects that cause damage to crops, trees, and plants. They also eat other soft-bodied insects such as moths, flies, and thrips. Ladybugs are easy to find in your garden because they tend to fly around during the day looking for food. If you see a lot of ladybugs in your garden, it’s a good sign that there may be some pest problems to deal with!
- They help pollinate plants: Ladybugs love pollen! When ladybugs visit flowers for nectar, they will also collect pollen on their bodies so it can be transferred from one plant to another when they visit another flower. Pollen allows plants to produce seeds and fruits, so when you have lots of ladybugs visiting flowers in your garden, it means more fruit!
- Ladybugs are excellent pollinators: They feed on pollen and nectar (although not all species do). Their bodies carry pollen from one flower to another during feeding, so they can be used to pollinate plants that need insect pollination. This includes fruit trees such as apples or pears, squash and melons, and some ornamentals like azaleas or roses. Using ladybugs instead of bees is that they don’t sting!

Are Grasshoppers Good for the Garden?
Grasshoppers are an annoying pest that can quickly destroy your garden if not controlled. However, grasshoppers are also beneficial to the garden and environment. Here are some reasons why:
- They help aerate the soil: Grasshoppers eat plants, but they also eat soil. This helps aerate the soil by loosening it up and making it easier for water and air to penetrate deep into the ground.
- They’re great for composting: Grasshopper bodies contain rich nutrients that can be used in composting. If you don’t want to use them in composting, simply bury them in your garden or yard so they can decompose naturally. This will add organic matter and nutrients back into your soil over time.
Are Praying Mantis Good for Your Garden?
Praying Mantises are a fun and fascinating addition to any garden. These amazing insects are not only beautiful, but they can also help keep your garden pest-free. Here are ways that praying mantises can benefit your garden:
- Praying mantises eat pests: The diet of a praying mantis consists of other insects, including aphids, flies, and mosquitoes. When these insects eat their prey, they usually strip off their exoskeleton and suck out their insides before spitting out the carcass. This makes them an effective natural pest control for your yard or garden.
- Praying mantises repel other insects: Praying mantises are very aggressive predators and will attack anything that moves within their line of sight. Because other insects see these bugs as predators, they try to avoid them. If you see a praying mantis in your yard, it won’t be long before other bugs leave the area entirely!
- Praying mantises are beautiful: Many people don’t think about how beautiful praying mantises are until they see one up close for the first time! They have brightly colored bodies with striking patterns that make them look like something straight out of a science fiction movie!
Are Slugs Good for Your Garden?
Slugs are a gardener’s worst nightmare. They can devour your crops, leaving behind trails of slime and destruction. But there is a silver lining to these slimy pests: slugs play an important role in the ecosystem.
Here are ways that slugs are good for your garden:
- They help with nutrient cycling: Slugs eat decaying matter such as fallen leaves and dead grass, which they digest and excrete as mucus-like slime called mucus. This mucus acts as a natural fertilizer for plants, helping them grow more quickly and efficiently than they would otherwise.
- Slugs are also food for other animals: Birds, frogs, toads, and snakes all eat slugs for their own nutritional needs. This helps keep populations of these animals healthy and ensures that there is plenty of food available for them in the wild when they need it most (during the winter months).
- Pollination: Slugs are essential to pollination processes in plants like strawberries and tomatoes, which rely on pollinators like bees or flies to move pollen from male flowers to female flowers so that fruit can form on plants like strawberries or tomatoes (or any other fruit-bearing plant).
- Slugs help control plant diseases: Plant diseases can be devastating to crops, especially if you’re growing tomatoes or potatoes with lots of fruits or tubers that need protection from fungi and bacteria. Slugs help keep those diseases at bay by eating them before they infect any more plants!
Are Ants Bad for Your Garden?
Ants can be a nuisance to your garden, but they also play an important role in the environment. Here are ways ants are bad for your garden:
- They may carry diseases: Ants carry many diseases that they can transmit to your garden plants. Some include leaf spot, powdery mildew, rust fungus, stem rot, and root rot. If the ants are eating your plant’s leaves or stems, they may also injure them in other ways, such as removing leaves from the plant or stripping away bark from tree branches.
- Ants can ruin your fruit: Ants love sweet things like fruit! If you have an ant problem in your yard, the chances are good that you’ll have an ant problem in your fruit trees too. If there is any sweet sap leaking from damaged fruit or flowers on a tree branch, it won’t take long for ants to find it and start feasting on it. This can cause the entire branch to die off!
Ants are not just the bane of picnics. They are also essential to your garden. Here are ways ants benefit your garden:
- Ants eat aphids and other pests: Aphids are tiny green insects that pierce plants and suck out their juices. Ants don’t like aphids because they’re a food source, so they eat them as fast as they can find them. This is good news for your plants because it means less damage from aphids (and fewer chemicals). Ants also eat slugs and other pests that you may have in your garden.
- Soil aeration: Ants aerate the soil by digging nest tunnels through the earth with their mouths (called mandibles). These tunnels allow oxygen and water to reach the roots of plants and make it easier for seeds to germinate by breaking up hard soil clumps into smaller pieces that can absorb moisture more easily.
Are Grubs Bad for Your Garden?
Grubs are the larval form of beetles and contain an insatiable appetite for your plants. They can decimate a garden in weeks and are a major pest problem in North America. However, there are some grubs that you can use for your garden to help improve it.
Here are ways grubs are bad for your garden:
- They eat holes into leaves: Grubs like to chew holes into leaves and stems, which causes them to wither and die. This creates gaps in your plant canopy, making it harder for your vegetables or flowers to receive the sunlight they need to grow properly.
- They destroy root systems: Grubs eat the roots of your plants from the inside out, which makes them more susceptible to disease and death. If you have a large infestation, there’s a chance that it will kill off all of your plants because there won’t be enough healthy roots left for them to grow on.
- They can transmit diseases: Grubs carry pathogens that can be transmitted through their saliva when they bite into the leaves of other plants (or humans). These pathogens include viruses, bacteria, and fungi that can infect humans and animals who consume infected food products such as beef or milk products from animals fed with contaminated hay or pasture grasses.
Here are ways grubs can benefit your garden:
- They aerate the soil: Grubs feed on the roots of plants and dig tunnels in the dirt as they do so. These tunnels provide air space between the soil particles, making it easier for water and nutrients to reach plant roots. The grub tunnels also make it easier for water to drain away from plants during heavy rains or watering.
- They add nitrogen to the soil: The larva excretes nitrogen when they tunnel through the ground, adding nitrogen back into the soil that may be lacking due to overuse or improper fertilization practices. Nitrogen is essential for healthy plant growth and development, so adding more of it into your soil can help keep your plants healthy and green all season long!
Of course, it is normal to fear insects when you see them in your garden, but they are not guaranteed to harm your plants. They can often be beneficial when used correctly (and in small doses). To get rid of insects that turn out to be problematic, there are many easy solutions that anyone can try out at home. Suppose you are concerned about an insect invasion in your garden. In that case, you should also take into consideration the facts and aspects described above, as well as the knowledge of your own garden’s situation.
