Aphids can also be washed off with a spray from a hose. They are too weak to hold on or crawl back up onto the plant. I had some aphids on a couple of my tomato plants for the first time last year and I got rid of them by hosing them off a few times and using some insecticidal soap.
You will have to wash them off a couple of times because the stream of water only removes the adults and more eggs will hatch over the next week or so. You will need to wash off those adults too.
