Answers: Little bean munching bastards grrrrrrr! Let's get them!
I don't know what they are as it depends what subdivision of the world you're in and there's loads of different brown bean munching shits, here's a short detail of bean pests http://ipm.ncsu.edu/ag295/html/bean_pea_...
If you look at lots certain shop bought pesticides masses of them contain pyrethrum, which is derived from chrysanthemum plants and can be used as an organic pest control!!
Soapy dampen is another simple pest control but needs to be applied regularly.
Another graceful one to make is garlic river as garlic is easy to bring hold of.
Sorry guys but I don't understand how rotenone powder (contains arsenic and sulphur) and hydrogen peroxide (a chemical bleaching agent) can even remotely be call organic.
I've copied some remedies for you to try, another decisive pesticide not mentioned below can be obtain by steeping rhubarb leaves and using the resulting water as a spray.
Derris (Derris elliptica, D. Malaccensis, D. uliginosa ): This shrub originate
from lowland areas of the Malay Archipelago. Freshly cut roots from 2 to 6cm
in diameter should be wash and cut into 5cm lengths. They should be
ground next to soap and a little marine. Soap helps the solubility of the
insecticidal ingredient. When completely shredded squeeze the soft out
through fine cloth. The solution should be diluted and used at once. To
obtain this solution the following quantity should be used: 1 part soap : 4
parts roots : 225 parts wet.
Pyrethrum (Chrysanthemum cinerariaefolium): The white flowerheads
possess insecticidal properties. Pyrethrum is most productive at altitudes of
1600 meters and ideally in semi-arid conditions where on earth winters are cool. On
richer soils the insecticidal properties are reduced.
Pick the flowers on a warm afternoon when the flower are fully open. Then pile up
into small heaps surrounded by the sun to warm through. Then spread out to dry on gooey
mats surrounded by a shady area. If they are to be stored, they inevitability to be kept in an airtight
container contained by the darkness. Light reduce the effectiveness of the
flowers.
Pyrethrum fluid: Mix 20g pyrethrum powder with 10 litres marine. Soap can
be added to make the substance more successful but it is not vital. Apply
hastily as a spray.
Yam bean (Pachyrrhizus erosus): The ripe seeds of this plant should be
collected to cause an effective spray. This act as a contact and stomach
poison.
Grind 65g of yam beans and mix well beside 12 litres of water. Spray on
artificial plants.
Garlic (Allium sativum): Garlic has a wide-ranging range of effects: insecticidal,
fungicidal, nematocidal and is important against ticks.
Garlic spray: Cover 3 finely ground garlic bulbs in juice paraffin for 2 days.
Stir in one colossal spoonful of soap and 10 litres of water. Use this spray
right away so as not to loose the effects of the spray.

Good luck with these, agree to me know how you get on.
I own been using Hydrogen peroxide 8% and found it to work powerfully on EVERYTHING.. best to get a big container from a pool shop though it is much cheaper than the super marketplace or chemist
