Not all insects are pests. There are, in truth, plenty of good bugs for your garden. Most growers recognize the help by these beneficial insects as well as the harm done by others. 

Insects That Are Good for the Garden

Beneficial insects fall into three main categories 

  • Pollinators: We depend on these insects—including bees, butterflies, flies, and moths. They pollinate our garden’s flowers. 
  • Predators: These insects kill pests by eating them. This classification includes things such as ladybugs, praying mantises, and green lacewing larvae. 
  • Parasitizers: These insects prey upon other insects. They are almost the same with predators but in a different way. They lay their eggs on or in the bad bugs and the larvae feed on the host insects when the eggs hatch. The primary members of this category are parasitic wasps.

In this article, we’ll help you determine whether the bug you see in your garden is harmful or helpful.  


Here’s a list of some of the best beneficial insects to have in your gardening space. 

Praying Mantises

A praying mantis can help you deal with any grasshoppers that are troubling you. These fierce predators will hunt many other pests that terrorize gardens. That includes moths, beetles, and flies. But, praying mantises are vicious. They may resort to eating other beneficial pests. That includes butterflies, bees, hummingbirds, and even their own kind!

Bumblebees, Honey Bees, Mason Bees 

Bees are usually known as nature’s best pollinators. Without them, we wouldn’t have as many flowers and plants.  

Bumblebees are sturdy and hairy. They are about 1.5 to 2.5 cm (approximately 0.6 to 1 inch) in length on average. They have broad yellow or orange bands wrapped around their black body. 

In nests or hives, honeybees are social insects and live together. Honeybees are remarkable for their dancing movements it performs in the hive. This is to communicate to its fellow bees about the location, distance, and size. They also discuss the quality of a particular food source in their surrounding area. 

Mason bees don’t make honey. But with their pollination abilities, they pack a punch. This allows plants to seed and multiply. They help increase fruit trees and berry canes to their yield. They cultivate flower landscapes to burst with color. 

Benefits of having bees in your garden: food crops are pollinated.

Bait honeybees with: Orchard fruits, mustards, cress, wildflowers, clover, blueberries, and hollyhock. 

Parasitic Wasps 

Parasitic wasps are very tiny, so you will not see them at work. But, they are very effective. 

Braconid wasps lay their eggs on the backs of tomato hornworms and caterpillars. It forms white cocoons that can be usually seen on the caterpillar’s back. If you see a caterpillar that has been parasitized, don’t kill it. Move it elsewhere in your garden, instead. The wasp larvae are going to take care of them and turn them into more wasps for you. In your tomato patch, these wasps will keep on doing their good work.

In the eggs of over 200 different insect pests, Trichogramma wasps lay their eggs inside. The tachinid fly resembles a small housefly. But it is an aggressive parasitization of corn borers, grasshoppers, and Japanese beetles. They also prey on squash bugs, green stink bugs, and gypsy moth caterpillars.

If there are beneficial insects, then there are also bad bugs that you need to get rid of. Here is the list: 

BOXELDER BUGS – It feeds on the leaves, which can cause some damage but usually very little. 

MEALYBUGS – Bugs suck plant sap. This weakens the tissue and causes stunted, distorted, discolored, spotted, or yellowed foliage. Large infestations of these bugs can cause premature leaf or fruit drop or worse, death.  

AZALEA LACE BUG – they pierce leaves and suck out the chlorophyll. This causes yellow dots on the top side of the leaves. Eventually, the foliage turns white, which is a sign of a dead plant.  

Tomato hornworm, Corn earworm, Imported Cabbage worm 

All three worms are voracious foliage eaters. They contaminate what’s left with their feces. Hornworms also will eat into green fruit. Corn earworms usually feed on developing tassels. Then, they will eat down through the kernels. Cauliflowers and broccoli are at risk with cabbage worms. They will chew on the heads of these vegetables.
