Grasshoppers are among the most difficult insect pests to manage in the garden. When numbers are low, they can be hand-picked and squashed. Floating row covers and other protective covers provide some protection if their numbers are not high. However, grasshoppers will eat through cloth or plastic row covers if they are hungry enough.
Most grasshoppers are general feeders, but they prefer young, green plants, especially lettuce, beans, corn, carrots, onions, and some annual flowers. Grasshoppers do their damage by chewing and can remove large sections of leaves and flowers in one sitting, sometimes devouring an entire plant. An odd grasshopper here and there is nothing to be alarmed about, but should you face a full invasion, there are some steps you can take to combat this destructive pest.
The best way to control grasshoppers is to apply a bait containing carbaryl around the borders of your garden. Make sure to re-apply baits after any period of rain. For non-edible plants, you can also use a spray directly on the plants. It usually helps to do a repeat spray every couple of weeks until they leave your garden. Make sure to spray late in the evening or early morning when bee activity is lower; you don't want to kill our important pollinators.
