buy some ladybugs … they LOVE aphids

Aphids suck the sap from the plant. They can destroy a whole plant.

google aphid control and do what is best.

I like the crush a handful so they will send off a pheromone warning the others of impending doom …

Aspiring, the most commonly used recommendation is to direct a fairly strong stream of plain water to the aphids to knock them off. The treatment will need to be repeated.

If you look carefully, you'll probably find the insects under the leaves, too....which would explain why the leaves are cupped. That's where your insecticidal soap would come in handy. Spritz some on the underside of the foliage.

As always, read and follow directions.

Thank you so much, everyone! Will do the crushing of some... soap the underside of leaves as well. Will look for some ladybugs and transfer some over to my poor plant!

Please don't forget the strong sprays of water....that's the number one most effective treatment.

Aphids suck the sap from the plant. They can destroy a whole plant.

They do indeed suck out the plant juices but aphids have never been blamed for the demise of a woody plant, like a viburnum. For one, they tend to be more seasonal than not and prey to so many different types of predators that they just don't develop that strong a foothold. If we are talking a young seedling then yes, aphids could do serious damage. Otherwise, their impact is almost exclusively cosmetic.
