Yep, lots of folks pray to have ladybugs in their garden. Then they squash anything they don't recognize. These little guys are fairly ugly but they work cheap.
Normally I would advise you to use the garden hose to squirt all the aphids away, but no, don't do that now. You would also be getting rid of the good guys. Just keep an eye on the situation for a while.
Another thing to look for are the ladybug eggs. Here is a video showing what to look for.
