How To Get Rid of Grasshoppers and Locusts?

Written by George Climer

Since the dawn of agriculture, plants have been plagued by ravenous insect pests. But no gardener wants grasshoppers in his garden, and no farmer wants to see the season’s crops eaten by locusts. How do you get rid of grasshoppers and locusts?

How to get rid of grasshoppers and locusts? To get rid of grasshoppers and locusts, use effective and safe remedies that won’t damage your greenery, including applying neem oil or pepper spray around your yard. You can also use chemical pesticides or hire a pest control specialist in cases of large infestations. 

If you want to learn how to get rid of grasshoppers and locusts, we are here to teach you. This article will also cover the differences between locusts and grasshoppers and how to keep grasshoppers and locusts out of your home and yard.

Locust vs. Grasshopper

It can be hard to tell the difference between locusts and grasshoppers. Locusts and grasshoppers look very much alike. Both locusts and grasshoppers have strong hind legs for jumping and strong mouthparts for chewing leaves. And most of the time, locusts and grasshoppers behave very similarly. 

Difference Between Locust and Grasshopper 

Grasshoppers do not come together in swarms like locusts that darken skies and strip fields and forests. Outside of the mating season, grasshoppers are solitary insects that will avoid each other if given a chance. 

Do Grasshoppers Turn Into Locusts?

Most grasshoppers do not form swarms. You might see many more grasshoppers than usual in a season. But those grasshoppers do not fly in unison like a locust swarm. There are a few species of grasshoppers that will, under certain conditions, seek each other out and swarm in search of new food. These grasshoppers are called “locusts.”



You are far more likely to see a grasshopper than a locust. Locust swarms are an uncommon occurrence – and thankfully so! Here are some helpful facts about grasshoppers.

What Is Grasshopper?

Grasshoppers are some of the most ancient animals. Fossilized ancestors of today’s grasshoppers date back to the Triassic Era. Both locusts and grasshoppers belong to the order Orthoptera and its suborder Caelifera and are closely related to katydids and crickets.

Do Grasshoppers Fly?

When grasshoppers feel threatened, they use their powerful hind legs to hop away from the situation. But grasshoppers have wings and can take to the air in search of food and mates. They don’t travel as far as a locust swarm, but grasshoppers are strong flyers.

How Long Do Grasshoppers Live?

Grasshopper nymphs are born in the springtime and become adults by summer. A grasshopper’s life span is around one year, but they spend most of that time in an egg pod. After hatching, grasshoppers will only live until the first frost. 

How Many Legs Does a Grasshopper Have?

Grasshoppers have four short legs and two long legs. They use their long legs for jumping. By rubbing the serrated edges of their legs against their body, they produce a distinctive chirping noise to attract mates.

What Does a Grasshopper Look Like

Grasshoppers have green, brown, or black bodies with large hind legs and enormous eyes. Some have red, yellow, or orange markings. Grasshoppers have a large pair of rear wings and long slender forewings. Adult grasshoppers range in size from 1-7 cm (½ to nearly four inches).  

Grasshopper Life Cycle

Grasshopper nymphs hatch from their egg pods in the springtime. When you see little green grasshoppers in gardens, you see the next generation of grasshoppers.  

Over the next few weeks, the grasshopper nymphs will molt five times until they become adult grasshoppers. Not long after, they will mate. The female lays eggs in sand or under leaf litter, then covers them with a sticky substance that hardens into a pod. In spring, the cycle repeats.

Where Do Grasshoppers Live?

Grasshoppers live on every continent except Antarctica. Scientists have identified over 8,000 species, and there are likely many more grasshoppers that have not yet been classified.  

What Do Grasshoppers Eat?

Grasshoppers are herbivores who will eat any part of the plant they can chew. Leaves, stems, flowers, fruit – it’s all lunch to a hungry grasshopper. When they need extra protein, grasshoppers will sometimes snack on an insect corpse.  

What Attracts Grasshoppers to Gardens?

Gardens are extremely enticing to grasshoppers when it has tasty crops, good hiding spots and only a few predators.

Although grasshoppers can consume a variety of plant materials, they are particularly drawn to alfalfa, corn, clover, grasses, and tiny grains. Dense planting of any of these crops may draw colonies of grasshoppers to your yard.

Furthermore, grasshoppers favor regions with a lot of weeds and plants since these environments offer more food options, areas to hide from predators, and sites for laying eggs. When there are fewer natural predators present, such as birds and spiders, grasshopper populations will inevitably increase.

Grasshopper’s Impact on Gardens

There is no need to be alarmed if there are a few grasshoppers in your garden. When they leave feces that is full of nourishment for the nearby plants, they can be helpful insects that play a significant part in the environment by feeding predators like birds and lizards.

A vegetable garden can be completely destroyed by a grasshopper infestation, though. Adults have the capacity to ingest up to sixteen times their body weight each day, which causes them to swallow the majority of the leaves while also rendering any surviving plants unable to survive. Your garden plants may be infested with grasshoppers if you notice numerous filthy, nibbled holes in the leaves, stems, fruits, or vegetables of the plants.



When your garden is getting nibbled to death by grasshoppers, you can’t help but think of the Biblical plague of locusts. And you realize things could be much worse. These grasshoppers may be chewing up your lettuce, but they’re not stripping your crops bare. 

So what is the difference between a grasshopper and a locust?  

What Is a Locust?

Most of the time, they are difficult to distinguish from other grasshopper species. They mate, eat, and live as solitary insects. But when they are crowded together with diminishing food, locusts form their notorious swarms. Locusts are a species of grasshopper that will swarm under certain conditions. The vast majority of grasshopper species will never swarm.

How Long Do Locusts Live?

Locusts only live for three to six months. But in one generation, under favorable conditions, their numbers can increase 16-fold.  

What Does a Locust Look Like?

What Does a Locust Look Like1

Most of the time, locusts look and behave like any other grasshopper. Until recently, scientists thought solitary locusts – locusts who were not swarming -were a different species than the larger, more brightly colored swarming locusts. 

When locusts swarm, their color changes, and their muscles grow larger, allowing them to fly for long distances. Swarming behavior happens through a flood of serotonin in the locusts’ brains, making solitary locusts behave like a unified group.

Locust Life Cycle

Locusts live in barren regions where food is scarce. When the rains come, their home is suddenly full of greenery. During these good times, the locusts come together and breed. Soon the rains end, and food becomes scarce again. 

As the locusts get pushed into ever-smaller patches of vegetation, they are forced into close contact with each other. Instead of flying off on their own, they come together like a school of fish. As they eat the last of their food, the hungry locust swarm takes off for greener pastures.

Where Do Locusts Live?

Locusts are usually found in a band stretching across sub-Saharan Africa south of the Sahara and into India. When they swarm, they can reach as far as Europe. Different species of swarming locusts live in Australia and South America.

What Do Locusts Eat?

A locust can eat its weight in vegetation every day. 2 grams might not seem like a lot. But a massive locust swarm can cover 100 square miles or more, with 40 million to 80 million locusts packed in half a square mile. That 100-square-mile swarm can consume as much food in one day as 8.75 million people! 

Locust’s Impact on Gardens

Locusts are infamous for the destruction they cause while feeding. They have insatiable appetites and powerful chewing mouth parts.

Locusts are a common result of overcrowding or a shortage of food, and they can inflict unmanageable damage due to their excellent flying abilities. Many farmers have experienced a sense of powerlessness as they saw the massive locust swarms falling upon their fields of crops.

In an instant, locusts will occasionally devour entire plants, while other times they ravage at by chance. While big migratory locusts are challenging to halt, preventive measures can be done to reduce damage.

How To Get Rid of Grasshoppers?

Now that we know more about grasshoppers and locusts, we can deal with the most critical question: What is the best way to get rid of grasshoppers?

How To Get Rid of Grasshoppers in Garden?

You can get rid of grasshoppers in your home with a molasses trap. Pour three tablespoons of molasses into a cup of water, then leave this in a waterproof dish or bowl. (Adding a teaspoon of cooking oil will help discourage bees and flies from landing in the mixture).

How to Get Rid Of Grasshoppers Naturally?

1. Neem Oil

Three tablespoons of neem oil should be added together with two quarts of warm water and a half-teaspoon of liquid dish soap. Grasshoppers’ growth will be slowed and even stunted by applying this mixture over plants.

2. Garlic Spray

Strong aromas like garlic, which might deter grasshoppers from entering your plants, are particularly effective at attracting their attention. 

To get rid of grasshoppers, try this garlic/red pepper spray:
