  1. 1

    Remove any dead plants, weeds and grasses that may be attracting insects to your plants.

  2. 2

    Create a barrier around your green beans with mulch. Mulch is not an insect-friendly material.

  3. 3

    Pour insecticide soap into a garden hose sprayer and spray it all over your green beans. Knock off any insects that you see with the spray from the hose.

  4. 4

    Make a band of tin foil, and wrap it around the base of each green bean plant.

  5. 5

    Pick off any insects left on your plant with your fingers. Place the bugs into a pail of water mixed with dish soap to kill them.

  6. 6

    Fill the chamber of a pump insecticide sprayer with a preventive insecticide. Spray the preventive over the plant in long, even strokes.

  7. 7

    Repeat the preventive process occasionally to keep the bugs away.

Tips and warnings

  • Switch the types of insecticide you use every so often to keep the insects from developing a tolerance.
  • Make sure the insecticides are safe to use on plants that will be consumed.
