Q&A for How to Get Rid of Grasshoppers

Insecticides that contain permethrin and carbaryl are most effective at killing grasshoppers.

While grasshoppers can be destructive to crops and gardens , they do play an active role in the animal and plant ecosystem, so it would not be beneficial to eliminate the species completely.

Grasshoppers are generally drawn to long unkept grass and they are also drawn to weeds.

Several plants can be planted as a deterrent including cilantro, horehound, and Chinese brake fern.

There is a biologic product called Nolo or Semaspore that you can put out. The grasshoppers eat it and it makes them sick. It won't get rid of all the grasshoppers, but it will reduce them numbers and cause them to reproduce less.

Spraying plants with soapy water keeps aphids off plants, and may work for grasshoppers as well. Put a small amount of dish washing liquid in a spray bottle with water and spray the plant. Planting cilantro, calendula, and sweet clover in your garden will keep grasshoppers away as well.

Try to lure the grasshopper out. You can try poking at it with a stick. Once it's out, squash it with your shoe or a textbook. For a more humane approach, you can also capture the grasshopper with a plastic cup and take it outside.

Plant cilantro around the crop or at least throughout. This may help to deter them. Netting or other covering can also help.
