Grasshoppers are considered herbivores, meaning they love to eat leaves, plants and vegetation. Because grasshoppers can jump 20 times the length of their bodies, they can get in trees and begin to damage them when they eat their leaves. You will need to take action to protect your trees from these grasshoppers.

Go to your local garden center and get a pack of nematodes. Nematodes are actually tiny roundworms that will eat any grasshoppers on your property. They are safe to use around children and small pets. Just distribute them near the trees you want to protect.

Sprinkle diatomaceous earth around the base of your tree. This natural dirt contains sharp edges that pierce the skeleton of the grasshopper when the grasshopper jumps on it. This causes the grasshopper to not be able to stay hydrated. The grasshopper will then die.

Blend your habaneros peppers with your water. Pour the mixture into an empty spray bottle. Add liquid castile soap. Spray the mixture around the base of your tree, and on some of the lower leaves. This is an all-natural repellent that will keep the grasshoppers from bothering your trees.

Use a chemical insecticide that contains the ingredient pyrethrin to protect your trees. This will kill any grasshoppers in the area without damaging your tree. Just make sure you follow all of the instructions when applying the insecticide.

Repel Grasshoppers

Grasshoppers may be cute when they’re depicted in cartoons, but they’re not so welcome in your garden or lawn. This allows them to make their way through your garden eating foliage, flowers, fruits and vegetables. Although grasshoppers are present every year, their numbers vary, depending on environmental conditions. Weather that leads to high populations of grasshoppers features warm, extended autumns followed by dry, warm spring seasons. Grasshopper adults tend to be active from June through September. Grasshoppers lay their eggs in the soil in the fall, and they prefer laying them in undisturbed, weedy areas. You can do this by covering crops with a row cover. Other sprays are made from plant materials that repel insects, such as neem oil from the neem tree. Such an individual will treat vegetation with an insecticide spray for grasshoppers.

Tip

Grasshopper baits contain a disease that will kill the grasshoppers after they eat it. The active ingredient in the bait is called Nosema locustae.

Neem oil can be sprayed on grasshoppers as a natural insecticide.
