A concept of how to attract beneficial insects

I made a video about how I attract beneficial insects.

I enjoyed your video Larry.
One of the things I do, that baffles people is wait/ do nothing. I think it's easy to kind of panic when we see a pest. To think we need to take control. I have found the last couple of years if I wait the problem resolves itself.
Yesterday my son pointed out a small clump of beans that was covered in aphids. He asked what I was going to do. I told him I was going to watch and see what happens.  If they are still there in a few days, I will spray them off with water.  Without some bad bugs to feed the predator bugs they will leave, then we are will be unprotected. I'm pretty sure he thinks I'm off my hinge. But... Today there were still aphids, but about 1/3 of what I saw yesterday.
