Japanese Beetles!!?

I have green bean plants in my garden with Japanese beetles all over them. They are eating the leaves completely off. Are there any natural remedies to get rid of the little pests? What can I do to get rid of them before they ruin my plants?

1. all I know about are the bag a bug bags that attracks them and they get trapped in the bag. They can be bought in hardware stores.
2. Least Toxic Japanese Beetle Controls There aren’t many natural controls for adult Japanese beetles. Birds aren’t partial to them and although some predatory wasps and flies have been imported, their population isn’t large enough yet to control the Japanese beetle problem. The most effective natural control is to go into your garden with a jar of soapy water and knock the beetles into it. Japanese beetles feed in groups, starting at the top of plants, so it’s actually pretty easy to fill a jar with them. Insecticidal soap will kill adult Japanese beetles is sprayed directly on the beetle. It does not have any residual effect, meaning that beetles that aren’t sprayed directly won’t be harmed. A word of caution about the pheromone beetle traps. They will attract beetles, but you’ll probably wind up with more beetles coming into your yard than you would have without the trap. The original intention of the traps was to track when and how many Japanese beetles were in the area, not as a means of eradication. Finally, if you have repeated intense infestations, you should check your soil in late summer to see if you have a large grub population. Lift a 1 sq. ft. section of turf. If there are more than a dozen grubs in this small area, consider treating your lawn with some type of grub control. However, not every garden that has a Japanese beetle problem is associated with a lawn full of grubs. The beetles can hatch in your neighbors lawn and find your tasty garden with very little effort. More Toxic Controls, to be used with Caution There are several insecticides labeled for use on adult Japanese beetles, including: * Bayer Advanced Garden Multi-Insect Killer Concentrate * Carbaryl (Sevin) * Neem extracts * Orthene * Ortho Bug-B-Gon Garden & Landscape Insect Killer Concentrate * Orthene Turf, Tree & Ornamental Insecticide * Spectracide® Bug Stop Multi-Purpose Insect Control Concentrate * Spectracide® Triazicide® Soil & Turf Insect Killer Concentrate These sprays will kill on contact and also have some residual effect. Keep in mind that these sprays will kill more than just the Japanese beetles, so use them only for extreme infestations. And again, Japanese beetles are only a pest for a little over a month, so don’t over react. Always read and follow label directions when using any pesticide.
