Attack of the Mexican Bean Beetles...

...and how we stop them!

These culprits are on our green beans, wax beans, lima beans, and kidney beans:
After performing a little twosome activity, the female beetle deposits these little goodies on the underside of the leaves:

Since we use organic methods and avoid pesticides, here's how we get rid of these pests:

The eggs take 4-5 days to hatch, so every 4-5 days we look under all the leaves and smite the eggs with our bare hands!

Does this work? It does give the beans plants a chance to reach maturity. After a certain point, there are too many plants and leaves to check, so we hand pick the beetles, larvae, and eggs while we pick the beans.
