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 grasshopper 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.

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.

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’ brain, 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!

How To Get Rid of Grasshoppers in House?

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).

When the grasshopper smells the sweet molasses, it will jump into the bowl, then drown as it becomes stuck in the liquid.  


Getting Rid of Grasshoppers Naturally

Other than neem oil, diatomaceous earth, and molasses, garlic and hot pepper also serve as natural grasshopper repellents.  

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

  1. Add four minced cloves of garlic and four chopped cayenne peppers to 6 cups of water.
  2. Simmer for 20 minutes on medium heat, then let the mixture cool overnight.
  3. Strain the hot pepper/garlic concentrate.
  4. Put one cup of this concentrate in a gallon of water, then spray it on your foliage.

You may wish to mist a test area on your plants first to ensure they are not sensitive to the mix. You will also need to reapply after every rain.

Scientists fighting locusts in Africa have explored using Nosema locustae, a single-celled parasite that kills locusts and grasshoppers. They have also considered importing an Australian wasp whose larvae eat grasshopper egg pods to keep locust populations down. So far, these methods have not stopped locust swarms, though they have become less common occurrences.
