What Are The Little Bugs on My Green Bean Plant

Updated: June 24, 2022

If you’re a gardener or have grown green bean plants before, you may have noticed little bugs crawling around on the leaves or stems of your plant. These bugs can be quite annoying and are often harmful to the health of your plants. In this article, we will discuss what these little bugs are, why they are on your green bean plant, and how to get rid of them.

What Are These Little Bugs?

The little bugs that commonly infest green bean plants are aphids. Aphids are tiny, soft-bodied insects that come in a variety of colors including green, black, brown, and red. They are about 1/8 inch long and have long antennae and two protruding tubes on their backside known as cornicles.

Aphids reproduce very quickly and can cause significant damage to your plants if left unchecked. They feed on the sap of your plant by piercing the stem or leaf with their sharp mouthparts. This can cause wilting, yellowing, or stunted growth in your plant.

Why Are They On My Green Bean Plant?

Aphids are attracted to the tender young growth of green bean plants. They like to feed on the sap of new leaves and stems that are still developing. They are also drawn to plants that are stressed or weakened due to environmental factors like drought, heat stress, or over-fertilization.

Aphids can also be introduced to your garden by other insects or animals that may carry them on their bodies. Once they find a suitable host plant, they will begin to reproduce rapidly and can quickly form large colonies.

How Do I Get Rid of Them?

There are several methods for controlling aphids on your green bean plants. Here are some effective strategies:

1. Handpicking

If you only have a few aphids on your plant, you can simply pick them off by hand and drop them into a bucket of soapy water. This method is best done in the early morning or late afternoon when the bugs are less active and easier to catch.

2. Insecticidal Soap

Insecticidal soap is a natural and safe way to control aphids on your green bean plants. It works by suffocating the bugs and disrupting their cell membranes. To use, simply spray the soap solution directly onto the affected areas of your plant. Be sure to follow the instructions on the label for best results.

3. Neem Oil

Neem oil is another natural and effective way to control aphids on your green bean plants. It works by interfering with the insects’ hormones and feeding behavior. To use, mix 1-2 tablespoons of neem oil with a quart of water and spray onto the affected areas of your plant.

4. Companion Planting

Companion planting is a technique that involves planting certain crops together to repel or attract insects. Planting herbs like mint, basil, or lavender near your green bean plants can help repel aphids and other pests.

FAQ

Can I eat green beans that have been infested with aphids?

While it’s generally safe to eat green beans that have been infested with aphids, it’s not very appealing. The bugs can leave a sticky residue on the beans and can be difficult to wash off.
