Haha, I was hoping you would ask! they tend to like small and umbel type flowers like sweet alyssum, yarrow, carrot/daucus/anne' lace types, dill, fennel, brassicas/mustards that have flowered (though be warned they can get weedy if left to self-seed.) I find that many of the flowers that attract various parasites are also good at bringing in adult predators (I'm guessing they has high nectar out put but that's really just a feeling)
"Tangle foot" is a natural(?) glue like substance that many orchardist apply to the trucks of fruit trees. It creates an impassable barrier to keep aphid farming ants from transporting aphids to the more susceptible areas of the trees. Its very important to weed and mow vegetation next to stumps so ants don't use it to climb passed the goo. I have heard of savvy ants sacrificing their lives to form body bridges to get passed the stuff.
Are you looking for more detail in some of the already mentioned categories also, like species that bring in predators ect.?
