Natural Methods Of Pest Control

This morning I woke up to find that a couple of the seed heads on my poppies were covered with black aphids. My first reaction was to run inside and pick up an insecticide but I remembered that I am trying not to use chemicals in my garden like I did last year. I almost searched on-line for one of those homemade concoctions to kill them but then I remembered that I had ladybugs somewhere in the garden.
