Imagine my chagrin this year when for the first time ever I decided to try growing dill and woke up one morning wondering why the upper most tender portions of the plants, which were ready for harvest, were drooping heavily sideways. Upon closer inspection those portions were covered with aphids. Well, I certainly didn't want to use anything as a remedy that would be toxic so went to several internet sites to find a workable natural solution.
By the way, you will also want to check plants, both edible and ornamental, near the infested ones. I found those little buggers were also beginning to munch on my pepper plants! This is the solution that worked for me in just a couple of days by adjusting assorted homemade recipe ingredients that I came across on the web. First, in the case of my dill, I cut off the upper portions, which were most likely no longer fit to consume anyway, rinsed the remaining portions of the plants with a heavy stream of water and then heavily sprayed the plants and the surrounding soil with a water bottle using the following recipe:
Note: On the third and fourth days I did find a couple of renegade aphids on the stems and gave them a quick spray. When I checked each morning thereafter, those same little guys were brown and dead. I have absolutely no clue how or why but it gave me great satisfaction. ;-)

There are insecticidal soaps on the market, however, I normally just take a small spray bottle with tepid water and a few drops of a mild detergent soap. It is much less expensive and I particularly like the "green" detergent soaps.
If buying ladybugs is not an option, I have been successful making a spray made from a boiled onion or garlic. Strain the juice and spray on the plants affected by aphids. This works for me. Tobacco juice is also effective.
Sticky tape can be an effective method for capturing many types of insects, including aphids. This is a page about using sticky tape for aphids.
This is a page about getting rid of aphids on roses. Aphids seem to like roses as much or more than we do.
