Q&A – What is eating holes in my green bean leaves?
Question:
Something is eating holes in my green bean leaves. What is it?
Answer:
This is the damage of the bean leaf beetles. They feed on the underside of leaves and like tender plant tissue. They look kind of like ladybugs, some have spots and others stripes and can come in several different colors. Bean plants can take a tremendous amount of leaf damage and are generally not affected by beetles eating the leaves. The beans will just grow more leaves. If necessary, there are some chemical controls for the bean leaf beetle: neem oil, insecticidal soaps, or pyrethrin. If you need a contact insecticide you can use carbaryl or bifenthrin.
