We had a huge problem with squash bugs this year, and since we don't use chemicals, I'm trying to find the best option for dealing with them so I can increase my harvest before they decimate my plants. I have heard of the soapy water and picking my hand. Has anyone used diatomaceous earth? I have tried to encourage beneficials in the garden, and hate to kill them, but, they clearly aren't helping much with the squash bugs. Is there an effective way to use them in just the squash beds? Would I sprinkle the plant or soil beneath?
