aphids, again

This tomato leaf is infested with aphids.  I am so tired of aphids.  I had them in my garden window starts.  I had them in my raised bed (and they get worse every time I use the remay cover).  And now I have them on my Topsy Turvy tomato plants.  Not much to do but go out with the hose on this rather rainy day, spray the heck out of the leaves, and hope they don't return.
