- Damage: Grasshoppers can quickly devour foliage, flowers, and fruit, causing significant damage to crops and ornamental plants.
If you suspect that grasshoppers are causing damage in your garden, it’s important to take action quickly before they have a chance to cause further harm.
Non-Toxic Solutions
1. Build Barriers
One of the easiest ways to keep grasshoppers away from your crops is to create physical barriers around your garden. This can include using netting or row covers to cover your plants, or building a fence around your garden to keep grasshoppers out.
2. Use Companion Planting
Companion planting involves planting certain crops or flowers together in order to ward off pests. According to some experts, planting marigolds or calendula alongside your other plants can help deter grasshoppers and other insects.
3. Introduce Natural Predators
Another option is to introduce natural predators that can help control grasshopper populations. This can include animals like chickens, ducks, or guinea fowl, or insects like praying mantises or assassin bugs.
Natural Remedies
4. Garlic Spray
Garlic is known for its powerful anti-inflammatory and antibacterial properties, and some studies suggest that it can also help repel insects like grasshoppers. To make a garlic spray, simply mix several cloves of crushed garlic with water and dish soap, and spray directly onto your plants.
5. Neem Oil
Neem oil is a natural insecticide that can be used to control a variety of garden pests, including grasshoppers. To use neem oil, mix it with water according to the package instructions and spray onto your plants.
6. Diatomaceous Earth
Diatomaceous earth is a fine powder that is made from the fossilized remains of tiny aquatic organisms called diatoms. When insects come into contact with diatomaceous earth, the fine particles cut through their exoskeletons, eventually leading to their death. To use diatomaceous earth, dust it onto your plants or sprinkle it around the base of your garden.
7. Citrus Spray
Citrus fruits like lemons and oranges contain compounds that can help repel insects like grasshoppers. To make a citrus spray, simply mix equal parts water and citrus juice or zest, and spray onto your plants.
Chemical Solutions
8. Insecticidal Soap
Insecticidal soap is a type of pesticide that is made from natural ingredients like potassium salts of fatty acids. This soap can be used to control a variety of garden pests, including grasshoppers. Simply dilute the soap with water according to the package instructions and spray directly onto your plants.
9. Pyrethrin
Pyrethrin is a natural insecticide that is derived from the chrysanthemum flower. This pesticide is effective against a range of insect pests, including grasshoppers. To use pyrethrin, mix it with water according to the package instructions and spray onto your plants.
10. Bt (Bacillus thuringiensis)
Bt is a natural insecticide that is made from a type of soil bacteria. This pesticide is commonly used to control caterpillars and other pests, but it can also be effective against grasshoppers. To use Bt, mix it with water according to the package instructions and spray onto your plants.
Preventing Grasshopper Infestations
11. Clean Up Garden Debris
Grasshoppers are attracted to places where they can find shelter and food. To prevent infestations, be sure to remove any garden debris, fallen leaves, or overgrown vegetation that could harbor grasshoppers.
12. Water in the Morning
Grasshoppers are most active in the early morning and late afternoon, so it’s important to water your plants in the morning to avoid attracting these pests during their most active times.
13. Rotate Crops
Rotating your crops can help prevent grasshopper infestations by disrupting their feeding patterns and forcing them to move to a new location in search of food.
14. Use High-Quality Soil
Healthy plants are more resistant to pests and diseases, so be sure to use high-quality soil and fertilizers that will help your plants grow strong and healthy.
15. Choose Resistant Plants
