How to Keep Critters off of Green Bean Plants


Green beans are also sometimes called runner beans. Green beans are not only a tasty vegetable, but they are good for you as well. These beans are easy to grow in a home garden. When you grow the green beans yourself, you can be sure no chemicals were used on them. Unfortunately, your green beans will be susceptible to many different types of critters. You will have to take preventive measures to keep those critters away so that your green bean plants can grow nice and healthy.

Removing Common Critters

Step 1

Spray off any aphids you see using your garden hose. Of course, this method only works after you have spotted the aphids and doesn't keep them from coming back. It is, however, an excellent temporary option.

Step 2

Purchase a packet of nematodes from your nearest garden center. Follow the directions on the packet to mix the nematodes with water. Spray them on the soil near your green bean plants. These tiny worms will eat critters such as slugs from the inside out, and they won't harm your green bean plants.

Step 3

Pick off any caterpillars, worms or crawling insects that you see. You may want to wear a pair of gloves when you do this. You can then release the critters in to a wooded area away from your home, or you can squish them and toss them in the garbage.

Homemade Insecticidal Soap

Step 1

Fill a gallon bucket with water.

Step 2

Add dish soap and vegetable oil to your bucket and mix the three ingredients.

Step 3

Pour the liquid in to an empty spray bottle. You will have liquid left over. You can use it to refill your empty spray bottle as needed.

Step 4

Spray your green bean plants with this homemade insecticide once each morning. None of the ingredients will harm your green beans, but they will keep critters far away.

Tips and Warnings

  • Do not use chemicals to keep the critters away from your green bean plants. The chemicals will be absorbed in to the green beans. When you go to eat the green beans, you will be eating the chemicals as well.
