Erika, may I add a couple of thoughts here too? If you spray any of the above remedies, do so in the evening to avoid the active time of day for your bees. Also don't spray anything on a windy day, you'll get the stuff where you don't want it. Even a mild soapy water solution can be photo-toxic (I think that's the term) which means if the sun shines on the leaves with the stuff on them, it will burn the leaves.
Also, I always try the most non-toxic solution first, then keep a close eye to see if it worked for a few days. Rinsing the plants off with a strong spray of water from the hose will usually wash away most if not all your aphids. If you have an adjustable sprayer, I use the "mist" setting and it is gentle on the foliage but plenty brisk enough to wash off the bugs.
