how do i get rid of grasshoppers that are eating my citris trees?

Answer 1

The grasshoppers will die on their own soon.
Soap solution by itself will keep off a variety of insects.
Mulching grasshoppers is not a deterent, save the hassel.
Pepper is good for small plots to keep animals away.

Just spray with soap and water.

Answer 2

Hi,

This 'remedy' has worked for me on my roses, when grashoppers were devouring them last summer:

Ingredients:

1/2 cup of dead insects (grasshoppers) gross, i know, but just get to squishing+collecting as many as you can.
1 Tablespoon of dishwashing liquid
1 Tablespoon of cayenne pepper
2 cups of water

Instructions:
Put all of these ingredients in an old blender (MAKE SURE IT IS ONE YOU WILL NEVER USE FOR FOOD!) and puree the heck out of them. Strain out the pulp using cheesecloth or old pantyhose. Dilute the remaining brew at a rate of 1/4 cup of brew per 1 cup of water. Apply with a hand held sprayer to the point of run off.
