The grasshoppers are insects belonging to the suborder Caelifera, within the order Orthoptera. They devour the plant voraciously. They consume plant almost half of their daily body weight. Because of this, they are considered to be dangerous pests when they affect cereals, vegetables, grasses, flowers, lawns, etc.; both adults and nymphs eat the leaves and stems of plants.
Although the greatest damage is obviously recorded when populations are high, even small groups of grasshoppers can cause significant damage. They can cause various problems, defoliation is the greatest, although grasshoppers can find other food sources such as ripening fruit and grains, causing even more damage.

Signs of Infestation
How to know if there are grasshoppers in the garden? First, you have to get the answer to the question because the wrong treatment can damage your garden.
The grasshoppers lay their eggs in late summer. These eggs spend the winter underground and hatch in early spring. As soon as they hatch, the grasshopper nymphs immediately begin to consume plant matter in that area, and as they grow and deplete the food supply, they begin to move to new areas.
The presence of grasshoppers is the clearest sign of infestation, although noticing that leaves are missing or are nibbled, it is also a sign that your crops are under attack. Attempts to control grasshopper populations tend to be more successful if the area is small and relatively isolated.
Before reaching maturity, grasshoppers cannot go very far, because they have no wings, but once winged adults can fly several kilometers in search of new food sources.
They make holes in the plant’s tissue, as well as in the leaves. You can also find the dark droppings of the grasshoppers on the leaves of the plant. The fruits may also look like they are not developing properly.

1. Spread Neem oil for Grasshoppers
Neem oil is derived from the seed of the Neem tree. Neem oil both reduces or stops the growth of insects and sterilizes certain species. The most useful natural insecticides are Neem oil. you should make sure to apply it as soon as possible because Neem oil works best against grasshopper nymphs as well as on larvae of other undesirable insects.
Mix 2 tablespoons of neem oil with 1 gallon of water. Shake the solution and spray it on the plant surface.
The use of molasses is an effective way to kill these annoying pests. Molasses are a known attraction for grasshoppers. It consists of a sweet smell.
To remove grasshoppers-
Simply mix dilute molasses (a couple of tablespoons) and water in a shallow bowl. Place the bowl in the most infected area. Grasshoppers will soon find themselves submerged in water being attracted to the smell.
You can bury several plastic tops cut off bottles in the garden. Fill them halfway with 10 parts of water and one part of molasses, which attracts grasshoppers. Feeling the sweet smell, the insects dive into the water and drown. After capturing some, the traps must be cleaned and refilled.
Recommended Molasses- Plantation Blackstrap Molasses
Note: Some even suggest using beer instead of molasses.

6. Boric Acid
Boric acid is used as an insecticide, herbicide, or fungicide. It is highly effective in killing grasshoppers, cockroaches, ants, silverfish, termites, and other harmful garden pests. Sprinkle the boric acid on that place where the grasshoppers appear most. Grasshoppers die of dehydration or starvation when the substance affects their metabolism and ability to absorb nutrients.

7. Diatomic Earth
Another effective home solution to get rid of grasshoppers, this powerful powder is made by turning the skeletons of algae (rich in silicon) into a powdered form. It is completely harmless (safer for pets) and non-toxic and can be used freely.

Sorghum is a plant that is not appreciated by grasshoppers. So you can plant near your garden, field or cornfields and they will move away.
9. Take the Eggs Out of the Ground
Grasshoppers have eggs that are left in the ground. If you dig them up, you will prevent the spread of grasshoppers. As you already know grasshoppers egg stay underground in winter and hatch in early spring. So you have to destroy the eggs before hatching.
10. Birds and Chickens
If you have a farm, you may happy to know that chickens like to feed grasshoppers.
11. Water and Light Against Grasshoppers
Fill a bucket with water and put a light on top. Pour a little oil into the water. The grasshoppers will be attracted by the light and when grasshoppers will touch the water, they can not move because of the oil.
12. The Ordinary Flour
The ordinary flour also works: spraying it on the foliage, the mouths of the grasshoppers get stuck and cannot eat more, or if swallowed, they get sick and die.
13. Natural Predators
Along with the weather, natural enemies are the most important factor in controlling the grasshopper destruction. In some localized areas, these natural predators can cause even more death than the weather. Some attack when grasshoppers are still underground waiting for spring. Others attack nymphs and adult grasshoppers.
Bombilids and meloids lay their eggs on the ground, near the grasshopper’s eggs. When their larvae hatch, they locate the grasshopper egg pods and feed on them. Spiders, wasps, and many species of birds feed on nymphs and adults.
Natural predators keep pests located in that area under control and stop the proliferation of new grasshoppers, so if you have the possibility of attracting these predators to your property, you can resolve the matter without delay.
The best option is to attract the birds to your garden or have poultry. Seagulls, hawks, crows, crowned larks, partridges, and cranes are all grasshopper predators, well known for digging and devouring eggs, cleaning an area of up to 600 meters of pods.

Chemical Methods to Get Rid of Grasshoppers
The recommended best chemical insecticide for grasshoppers– Southern Ag Carbaryl 5 Percent Sevin Dust (Controls Insects)
Although there are several natural insecticides available against grasshoppers, most have only a limited effect and need to be applied many times.
For those who want to use organic products in their garden instead of resorting to chemicals, this can be discouraging, since the elimination of grasshoppers or lobsters is not immediate, it takes time.
However, the use of botanical and biological products to kill grasshoppers and lubber grasshoppers or lobsters is an effective alternative to consider, especially if you do not face a large population.
Most of the time, a chemical solution will be the most effective and we recommend that use it as soon as you notice the first signs of grasshopper infestation.
Younger grasshoppers will concentrate on the areas in which they hatched, and the application of the product will thus be much easier. The older the grasshoppers, the harder it is to control them.
Usually, if you live at low altitude, the best time to apply the treatment would be around May, if you live in higher areas, the best time would be in early June.
In terms of the active substance, you should choose an insecticide that contains carbaryl or permethrin. Treat the entire yard or garden, paying special attention to possible incubation areas, such as ditches, high areas, pastures, or weeds.
Because the grasshoppers move a lot, it would not be reasonable to expect immediate results; Repeated applications are the key, and this treatment can even help with the control of other annoying insect species.
Other chemical methods that you can use involve the use of baits containing carbaryl, which will kill the grasshoppers once ingested. If you decide to do this, remember to always renew them after a rainy day.
Once the grasshoppers have reached adulthood, you can also apply insecticides to your plants. However, be sure to use only approved and safe insecticides to be applied to plants.
Prevention and Control of Grasshoppers
Grasshoppers can be difficult to treat permanently, but not impossible. Start by placing protection around the plants in your garden. Organize your patio or garden with lilac, pink moss, verbena, sage, juniper, or jasmine. Pumpkin, tomatoes, and peas plants that repel grasshoppers.
Plant flowers, such as marigolds, sunflowers, daisies, nearby to attract beneficial insects such as a slide, which will attack grasshoppers.
Although with other insects it is usually better to cut the grass regularly. In this way, the grasshoppers will have a source of food there and will no longer invade the garden.
By plowing the soil, you can interrupt the life cycle of grasshoppers and prevent the upbringing and emergence of a new generation. Since they lay their eggs in late summer, to hatch in spring, you can use this method in early spring and destroy the egg pods they have laid.
Using the plastic covers along the rows, or aluminum wire mesh. Keep in mind that the fabric will not be effective, as grasshoppers can chew it and easily pass through it. If you want to eliminate the grasshoppers, fill a bucket with a mixture of soap water and pour on the soil, which will help to die grasshoppers larva.
