They are about the size of aphids and are soft bodies but they are yellow! What are they? Pest? Scourge? Or nothing to stress horribly about?
Just googled it, apparently they ARE yellow aphids, sorry and thanks for anyone's attention
Oleander aphids can also be found on milkweed, in case you have any of that. Better work on getting rid of them....they are evil.
Just spray them with a hose blast. That will take care of them.
Then repeat as needed, perhaps every several days.
Oh aphids come in all shades of the rainbow, even bright red.
