Controlling Squash Bug Larvae on Green Beans

Question: I have small yellow, round, fuzzy bugs on my green beans, wax beans, and lima beans, plus tiny yellow eggs on leaf undersides. Squishing them leaves yellow goo. What are they and how do I control them?

Answer: Squash Bug Nymphs

These are the larvae (nymphs) of squash bugs. The yellow residue is their defensive secretion.

Organic Control: Pyrethrum

Apply pyrethrum, an organic insecticide derived from chrysanthemum flowers. It's non-toxic to humans and pets but highly effective against most garden insects. Available at local garden centers or online from retailers like Gardens Alive and Planet Natural.

Application Tips

• Spray thoroughly, covering leaf undersides where eggs and nymphs hide
• Apply in early morning or evening to avoid harming pollinators
• Repeat as needed per label instructions

Early intervention prevents adults from laying more eggs and reduces damage to your bean crops.
