How to Stop Insects From Eating Green Bean Plants

Updated February 21, 2017

Spring is the best time to plant green beans for the summer; however, many insects will join you in the garden at this time. You will need to be diligent and persistent if you want to keep the insects from eating your green bean plants. First, bugs will need to be removed, followed by a series of cleaning and safety measures. By following a simple regime of removal and prevention, you can keep your green beans safe and the insects away.

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

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

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.

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

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.

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

Repeat the preventive process occasionally to keep the bugs away.


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.
