last ditch aphid control method

I need help.

My snake beans really need help.

They are absolutely infested with brown aphids. So much so that the leaves are going yellow and falling off. It's a pretty sad sight. Every year we end up with aphids somewhere but usually we just rub them off with our hands and resort to milk/ chili water spray if it gets beyond that.

This year started the same way but the conditions must be perfect for aphids or else they are a particularly randy bunch as things are now seriously out of control.

So far we have sprayed with milk (2% and 3.6% just to be sure), chilli water and diluted tar from the chimney which was something neighbour A swore by.

But nope. If anything they are still multiplying.

I am about to break down and go and buy something nasty at the hardware store.

I don't want to but at this rate I will not get to eat a single snake bean.....

Any home remedies we haven't tried yet?

For the sake of the beans and my commitment to chemical free gardening...

Try a teaspoon of soap (Dr. Bronner's peppermint is what we use, I don't know if others will work!) in a tsp of water. Totally destroyed our aphids.

Aren't ladybirds supposed to be good for aphid control?

Thank you for the ideas! Soap and water we hadn't tried but will next time. A teaspoon and a teaspoon sounds like a tiny amount...

Ladybirds and ants are natural predators but we would need to round up all the available bugs in Nagano to make a difference I'm afraid.

We decided to cut our losses and pull up the whole row of beans. Huge pity but better than resorting to chemicals. boo hoo
